EXECUTIVE SUMMARY
Testing of the Ecological Tanks Aqua Safe Model AS500L was conducted under the provisions of NSF/ANSI
Standard 40 for Residential Wastewater Treatment Systems(August 2005 revision). NSF/ANSI Standard 40
was developed by the NSF Joint Committee on Wastewater Technology.
The performance evaluation was conducted at the NSF Wastewater Technology Test Facility located in
Waco, Texas using wastewater diverted from the Waco municipal wastewater collection system. The
evaluation consisted of sixteen weeks of dosing at design flow, seven and one half weeks of stress testing
and two and one half weeks of dosing at design flow. Dosing was initiated on February 12, 2007. After a
three-week start up period, sample and data collection for the test was officially started on March 5, 2007.
Sampling started in late winter and continued into the summer, covering a range of operating temperatures.
Over the course of the evaluation,the average effluent CBOD5 was 2 mg/L, ranging between<2 and 6 mg/L,
and the average effluent total suspended solids was 5 mg/L, ranging between <2 mg/L and 45 mg/L.
The Aqua Safe Model AS500L produced an effluent that successfully met the performance requirements
established by NSF/ANSI Standard 40 for Class I effluent:
The maximum 7-day effluent arithmetic mean was 4 mg/L for CBOD5 and 16 mg/L for total
suspended solids, both below the allowed maximums of 40 and 45 mg/L respectively. The
maximum 30-day effluent arithmetic mean was 3 mg/L for CBOD5 and 11 mg/L for total
suspended solids, both below the allowed maximums of 25 mg/L and 30 mg/L respectively. The
effluent pH during the entire evaluation ranged between, 6.8 and 7.0,within the required range
of 6.0 to 9.0. The Model AS500L met the requirements for noise levels (less than 60 dbA at a
distance of 20 feet), color, threshold odor, oily film and foam.

PREFACE
Performance evaluation of residential wastewater treatment systems is achieved within the provisions of
NSF/ANSI Standard 40: Residential Wastewater Treatment Systems(revised August 2005), prepared by the
NSF Joint Committee on Wastewater Technology and adopted by the NSF Board of Trustees.
Conformance with the Standard is recognized by issuance of the NSF Mark. This is not to be construed as
an approval of the equipment, but a certification of the data provided by the test and an indication of
compliance with the requirements expressed in the Standard.
Plants conforming to Standard 40 are classified as Class I or Class II plants according to the quality of
effluent produced by the plant during the performance evaluation. Class I plants must meet the requirements
of EPA Secondary Treatment Guidelines'for five day carbonaceous biochemical oxygen demand(CBOD5),
total suspended solids(TSS)and pH. Class I plants must also demonstrate performance consistent with the
effluent color, odor, oily film and foam requirements of the Standard. Class II plant effluent must have no
more than 1% of samples exceeding 60 mg/L CBOD5 and 100 mg/L TSS.
Permission to use the NSF Mark is granted only after the equipment has been tested and found to perform
satisfactorily,and all other requirements of the Standard have been satisfied. Continued use of the Mark is
dependent upon evidence of compliance with the Standard and NSF General and Program Specific Policies,
as determined by periodic reinspection of the equipment at the factory,distributors and reports from the field.
NSF Standard 40 requires the testing laboratory to provide the manufacturer of a residential wastewater
treatment system, a report including significant data and appropriate commentary relative to the performance
evaluation of the plant. NSF policy specifies provision of performance evaluation reports to appropriate state
regulatory agencies at publication. Subsequent direct distribution of the report by NSF is made only at the
specific request of or by permission of the manufacturer.
The following report contains results of the entire testing program,a description of the plant, its operation and
key process control equipment, and a narrative summary of the test program, including test location,
procedures and significant occurrences. The plant represented herein reflects the equipment authorized to
bear the NSF Mark.

1.0 PROCESS DESCRIPTION
The Aqua Safe Model AS500L wastewater treatment system utilizes an extended aeration,activated sludge
processes to achieve treatment. In the activated sludge process, microorganisms remove soluble
contaminants from the wastewater, utilizing them as a source of energy for growth and production of new
microorganisms. The organisms tend to be flocculent and form clumps, or floc, that physically entraps
particulate organic matter. The organic matter is attacked by extracellular enzymes that solubilize the solids
to make them available to the microorganisms as a food source. The conversion of the organic matter from
soluble to biological solids allows the removal of the organic matter by settling of the solids in the treatment
process. 2
Extended aeration is a modification of the activated sludge process in which the microorganisms are allowed
to remain in the treatment process for long periods of time. The large inventory of biological solids in the
process provides a buffer for shock loading of organic matter. The long aeration period allows for the
organisms in the system to consume themselves, reducing the total amount of solids produced by the
treatment process.
The organisms primarily responsible for the degradation of the organic matter are facultative bacteria in the
aerobic state. As such, the transfer of oxygen into the wastewater by an aeration system is critical to the
treatment process. The aeration system also provides for the mixing of the wastewater and organisms to
provide contact between the organic contaminants in the wastewater and the organisms that provide for
removal of the contaminants. For this reason, an activated sludge process is referred to as a suspended
growth system. Interruption of the aeration system for a long period of time, such as days, can have a
serious impact on the process.
2.0 PERFORMANCE EVALUATION
2.1 Description of Plant Evaluated
The Aqua Safe Model AS500L system tested in this evaluation has a rated capacity of 500 gallons per day
(gpd). Specifications and drawings are included in Appendix A. The system achieves treatment by a flow
through process. Continuous aeration is provided by a rotary vane air pump through three anchored
diffusers. Settling is accomplished in a cone shaped clarifier set in the middle of the aeration compartment.
The plant is constructed of fiberglass,with a total liquid capacity of approximately 910 gallons. The aeration
compartment has a total liquid capacity of 755 gallons and the clarifier has a total liquid capacity of 155
gallons.
Wastewater enters the aeration chamber. Mixing in the aeration chamber is achieved by release of
compressed air near the bottom of the chamber through a series of four anchored diffusers. The plant was
operated with continuous aeration during the test. A conical shaped clarifier is located internal to the process
tank to provide for separation of the solids from the mixed liquor. The mixed liquor passes into the bottom of
the clarifier by hydraulic displacement as wastewater enters the aeration chamber. Solids settled from the
wastewater are drawn back into the aeration chamber from the bottom of the cone by the hydraulic roll
created by the air released in the aeration chamber and are dispersed by the mixing induced by the aerator.

Final Report without the expressed written consent of NSF International. July 2008

Discharge of the clarified effluent occurs through a submerged tee assembly located below the clarifier
surface to prevent discharge of solids that may float on the surface of the clarifier.
2.2 Test Protocol
Section 8 of NSF/ANSI Standard 40 protocol,"Performance Testing and Evaluation", is included in Appendix
B. Start up of the plant was accomplished by filling the plant with 2/3 water and 1/3 raw sewage. The plant
was then dosed at the design loading rate of 500 gpd as follows:
6 a.m. to 9 a.m. - 35 percent of daily rated capacity (175 gallons)
11 a.m. to 2 p.m. - 25 percent of daily rated capacity (125 gallons)
5 p.m. to 8 p.m. - 40 percent of daily rated capacity(200 gallons)
Dosing was accomplished by opening an electrically actuated valve to feed wastewater to the test plant.
Five gallon doses were spread uniformly over each dosing period to comprise the total dose volume for the
period.
After a start up period (up to three weeks at the manufacturer's discretion), the plant is subjected to the
following loading sequence:
Design loading - 16 weeks
Stress loading - 7.5 weeks
Design loading - 2.5 weeks
During the design loading periods, flow proportioned 24-hour composite influent and effluent samples are
collected five days per week. The influent samples are analyzed for five-day biochemical oxygen demand
(BOD5) and total suspended solids (TSS) concentrations. The effluent samples are analyzed for
carbonaceous five-day biochemical oxygen demand (CBOD5), and total suspended solids (TSS)
concentrations. On-site determinations of the effluent temperature and pH are made five days per week.
Stress testing is designed to evaluate how the plant performs under non-ideal conditions, including varied
hydraulic loadings and electrical or system failure. The test sequence includes (1) Wash Day stress, (2)
Working Parent stress, (3)Power/Equipment Failure stress,and (4)Vacation stress. Detailed descriptions of
the stress sequences are shown in Appendix B.
During the stress test sequences, 24-hour composite samples are collected before and after each stress
dosing pattern. The analyses and on-site determinations completed on the samples are the same as
described for the design load testing. Each stress is followed by seven consecutive days of dosing at design
rated capacity before beginning the next stress test. Sample collection is initiated twenty-four hours after
completion of Wash Day,Working Parent,and Vacation stresses,and beginning 48 hours after completion of
the Power/Equipment Failure stress.
In order for the plant to achieve Class I effluent it is required to produce an effluent, which meets the EPA
guidelines for secondary effluent discharge':
(1) CBOD5: The 30-day average of effluent samples shall not exceed 25 mg/L and each 7-day
average of effluent samples shall not exceed 40 mg/L.
07/03/055/0030 This report may not be reproduced in whole or in part Page 7 of 55
Final Report without the expressed written consent of NSF International. July 2008

(2) TSS: Each 30-day average of effluent samples shall not exceed 30 mg/L and each 7-day
average of effluent samples shall not exceed 45 mg/L.
(3) pH: Individual effluent values remain between 6.0 and 9.0.
Requirements are also specified for effluent color,odor, oily film and foam, as well as maximum noise levels
allowed from the plant.
2.3 Test Chronology
The system was installed under the direction of the manufacturer on May 10, 2006. The
infiltration/exfiltration test, during which the entire system was tested for leaks, was completed on May 11,
2006. The unit was filled with 2/3 fresh water and 1/3 raw sewage and dosing was initiated at the rate of 500
gallons per day beginning February 12, 2007. Sampling was initiated on March 5, 2005. The stress test
sequence was started on June 25,2007 and ended on August 15, 2007. Testing was completed on August
31, 2007.
3.0 ANALYTICAL RESULTS
3.1 Summary
Chemical analyses of samples collected during the evaluation were completed using the procedures in
Standard Methods for the Examination of Water and Wastewater'and USEPA methods4. Copies of the data
generated during the evaluation are included in Appendix C. Results of the chemical analyses and on-site

The interquartile range is the range of values about the median between the upper and lower 25 percent of all values.
Criteria for evaluating the analytical results from the testing are described in Section 8.5 of NSF/ANSI
Standard 40. In completing the pass/fail determination for the data, an allowance is made for effluent TSS
and CBOD5 during the first month of testing. The 30 and 7-day averages during this time may equal or
exceed 1.4 times the effluent limits required for the rest of the test. This provision recognizes that an
immature culture of microorganisms within the system may require additional time to achieve adequate
treatment efficiency. Effluent CBOD5 and TSS concentrations from the Aqua Safe AS500L during the first
calendar month of testing were within the normal limits and did not need to use this provision.
Section 8.5.1.1 of the Standard provides guidance addressing the impact of unusual testing conditions,
including sampling, dosing, or influent characteristics, on operation of a system under test. Specific data
points may be excluded from 7- and 30 - day average calculations where determined to have an adverse
impact on performance of the system, with rationale for the exclusion to be documented in the final report.
There were no such conditions during this test.

Sections 3.6 and 8.2.1 of the Standard define influent wastewater characteristics as they apply to testing
under the Standard. Typical domestic wastewater is defined as having a 30-day average BOD5
concentration between 100 and 300 mg/L and a 30-day average TSS concentration between 100 and 350
mg/L. The 30-day average influent remained inside this specified range for the duration of the test.
3.2 Biochemical Oxygen Demand
The five-day biochemical oxygen demand (BOD5)and carbonaceous five-day biochemical oxygen demand
(CBOD5)analyses were completed using the EPA Method 405.1. The results of the analyses completed on
the samples collected during the testing are shown in Figure 1.
Influent BOD5:
The influent BOD5 ranged from 36 to 540 mg/L during the evaluation,with an average concentration of 190
mg/L and a median concentration of 180 mg/L.
Effluent CBOD5:
The effluent CBOD5 concentrations ranged from <2 to 6 mg/L over the course of the evaluation, with an
average concentration of 2 mg/L. The median effluent CBOD5 concentration was 2 mg/L.
The Standard requires that the effluent CBOD5 not exceed 40 mg/L on a 7-day average or 25 mg/L on a 30-
day average. Table II shows the 7 and 30-day average effluent CBOD5 concentrations and the 30-day
average influent BOD5 concentrations.
The 7-day average effluent CBOD5 ranged from 2 to 4 mg/L. The 30-day average ranged from 2 to 3 mg/L
throughout the test. As shown in Table II,the Ecological Aqua Safe Model AS500L met the requirements of
Standard 40 for effluent CBOD5.
BOD5 Loading:
Over the course of the evaluation the influent BOD5 loading averaged 0.80 lb/day. The Ecological Aqua Safe
Model AS500L achieved an average reduction of 0.79 lbs/day.

I. INTRODUCTION
Ecological Tanks,Inc.was founded in 1994 by people with combined experience in installation,
pre-casting and the building industry. At Ecological Tanks, Inc. our main goal is to provide
products to professionals engaging in the business of distributing, installing and servicing home
wastewater treatment plants. To continue our service, we have dedicated ourselves to
manufacturing versatile products to simplify the task of installation and maintenance. This will
include all-in-one aerobic systems, the first one box control for the operation of pumps and
compressors, unique upsize controls and other products that are first in the on-site sewage
industry. With this unique diversity and know how, we can provide the help you need with your
on-site sewage treatment business.
Ecological Tanks,Inc. Model AS500,and larger,wastewater treatment plants have been tested
by Baylor University Department of Environmental Studies according to requirements listed in
NSF/ANSI Standard 40 and meets or exceeds Class 1 plant characteristic requirements.
In addition,Model AS500L(low profile)and larger plants in this series have been tested by NSF
and also meet or exceed the Class 1 plant characteristic requirements. Both model series were
tested without a trash trap, but may utilize one as an option to comply with state/local
requirements,or to reduce maintenance.
Some states require the use of a trash trap independent of these tests. Ecological Tanks, Inc.
recommends strongly the use of a trash trap or pre-treatment tank,especially in all cases where a
garbage disposal is being used or may be used. A minimum recommended size for a trash trap is
one-half the daily rated capacity of the unit. This recommendation enables enough capacity to
store non-biodegradable materials over an extended period of time (several years)to minimize
pumping requirements and overall maintenance. This size is also small enough not to interfere
substantially with the aerobic performance of the unit or to raise cost excessively.
The Aqua Safe® Model AS600+4NR was also tested by NSF and meets or exceeds both
Standard 40 Class I and Standard 245 requirements. The AS600+4NR was tested with a pre-
treatment (trash) tank and must be installed with a minimum of a 400 gallon capacity pre-
treatment tank.
II.AQUA SAFE®WASTEWATER TREATMENT PLANT PROCESS
DESCRIPTION
Aqua Safe® series models of wastewater treatment plants are made with an outer mixing
compartment and a center settling or clarifier compartment. They are in many ways similar to
large township or municipality sewage treatment plants. They employ an extended aeration,
activated sludge process. This type of treatment depends primarily upon the use of air that is
introduced by air passing from the aerator compressor to four air lines located around the
perimeter of the aeration mixing compartment. As wastewater enters the aeration mixing
compartment, simple hydraulic displacement is accomplished by the introduction of air which
promotes the growth of aerobic organisms in much larger quantities than would occur naturally.
These bacteria break down the organic solids in the wastewater. From the aeration mixing
compartment, mixed liquid enters the cone-shaped settling or clarifier compartment from the
bottom. No mixing occurs in this quiet zone where solids separate from liquid and settle to the
bottom of the clarifier and re-enter the mixing compartment. The liquid that separates from the
solids in the clarifier continue to flow upward to the discharge pipe.

3
The Aqua Safes Models ASS00, AS500L, AS600, AS600L, AS750, AS800L, AS1000,
AS1100L and AS1500 (Figures 1-3) are round tank configurations comprised of an aeration
mixing compartment and a center clarifier compartment. The AS600+4NR Model also includes
the use of a minimum 400 gallon pretreatment tank.
The results of the Aqua Safe,process are a clear, odorless effluent discharge which meets and
exceeds state and national water quality standards.

III. AQUA SAFE,RECOMMENDED PLANT INSTALLATION
INSTRUCTIONS
I. Inspect entire treatment plant and component parts.
2. Select location of plant site which is accessible to the home sewer discharge line,at least ten
(10)feet from the home foundation,in an area that will not receive vehicular traffic. Prepare
an excavation site by digging a hole at least one(1)foot larger than the treatment plant and a
depth that will allow for sufficient coverage leaving approximately three (3) inches of the
inspection port to extend above normal ground level. The depth of the plant will be
controlled by the depth of the building sewer outlet line plus the amount of proper fall
required from the building sewer outlet to the inlet invert of the plant. The prepared
excavation should have a solid, level bottom that will eliminate plant settling. Additionally,
the bottom of the excavated hole should be free of rocks or sharp objects. Aqua Safe,plants
should be installed on a bed of sand or undisturbed soil to provide a solid flat base.
3. Utilizing lifting lugs provided, carefully place the plant in the excavation. The inlet line
should slope down toward the plant and the outlet line should slope down away from the
plant. The plant should be level to within one (1) inch, edge to edge. Aqua Safe
wastewater treatment plants should only be connected to properly trapped and vented
plumbing systems in compliance with state and local plumbing codes.
4. Position the inlet and outlet lines and make the necessary connections. Clean-outs should be
installed at building sewer tie-in,any changes in direction of flow and at maximum intervals
of seventy (70) feet when using four(4) inch piping. The inlet line should be inserted and
glued into the inlet elbow and the discharge should be inserted and glued into the outlet
coupling. Open the inspection port on top of the plant and make sure the discharge tee
assembly is level and centered in the clarifier prior to connecting discharge piping. Fill the
tank with water to the point of flowing discharge before backfilling. Backfill evenly around
the plant,up to the bottom of the inlet and outlet piping,taking care not to damage the tank or
dislodge the piping. Backfill material must be void of rocks, gravel, heavy clay or any type
of material which might damage the tank.
5. If multiple tanks are installed in the same excavation, tanks should be positioned as close
together as possible. Preferably, they should be a minimum of twelve(12) inches and not
more than twenty-four(24)inches apart. The piping connecting the tanks should have a fall
of 1/8 to 1/4 inch per foot.
6. The aerator compressor must be installed in a well ventilated, relatively clean and dry
location. Install the aerator compressor on the treatment plant's tank top or at a remote
location no more than one hundred (100) feet from the treatment plant. The aerator
compressor is supplied complete with all discharge fittings. Install 3/<inch schedule 40 PVC
piping(supplied by others)between the aerator and treatment plant. Be careful not to allow
any debris, dirt or mud in the airline during installation. A minimum of twelve(12) inches
ground cover is recommended over the'/,inch schedule 40 PVC air piping.
7. The electrical controls for the aerator compressor, visual and audible alarms for compressor
failure and high water conditions,dose/spray pump and/or timer are contained in a weather
proof enclosure. (See figures 4-22). It may be installed in any above ground area where the
warning light is visible to the owner during the course of a normal day's activities. It is

13
recommended that the control box be at least six(6)inches above ground level and in view of
the aerator compressor housing. All electrical wiring must comply with applicable standards
and shall conform to the requirements of the most current revision of the National Electrical
Code. All electrical components not supplied must comply with U.L. standards. We
recommend that all electrical connections be made by a licensed electrician.
8. Install electrical wiring (provided by others) to interconnect the aerator compressor and
alarms to the electrical control panel. (Reference applicable field wiring diagrams.) A
minimum of twelve(12)inches of ground cover is recommended over underground electrical
conduit and wiring.
9. If required, install the application pump in the pump tank. Most aerobic system designs that
include as a method of effluent disposal surface spray, subsurface drip, or low pressure
dosing should include the proper sized pump for the job. If not,once the pumping conditions
are determined,selection of the right pump will be determined by two factors,pump capacity
and total head needed. You must match the pump as closely to your conditions as possible to
get maximum pump efficiency and dependable operation. Install and set the float switches to
the appropriate level to comply with design and state requirements. (See pages 24-25).
I 0. Run approved conduit and wiring to the pump tank from the control panel and have a
qualified electrician make wiring connections. All conduit running from the pump tank to
control panel must he sealed with conduit sealant to prevent moisture or gases from entering
the panel.
11. The aerator compressors used on Aqua Safe®wastewater treatment plants run continuously.
They provide relatively quiet, energy efficient operation. Once properly connected, the
electrical control box is to be closed. Operate the aerator compressor by placing the on/off
electrical circuit(provided by others)in the ON position.
12. Turn on aerator compressor and check all air piping and fittings for leaks. This can be
accomplished by preparing a saturated solution of soap and water and applying to entire run
of pipe and fittings. If a leak is detected,effect repairs.
13. Carefully backfill all underground lines and the rest of the plant's excavation in a manner
which will not cause damage to the completed installation.
14. The Aqua Safe®plant is ready to receive incoming sewage.
IV. AQUA SAFE®PLANT START UP
Initially the Aqua Safe® wastewater treatment plant is filled with clean water, usually from an
owner's water supply. As stated in the installation instructions,once all proper connections have
been completed and it is filled with water and the aerator compressor turned on, the system is
now in operation. For the treatment plant to be biologically stable, it will take from four(4) to
twelve (12)weeks after first using the plant to develop a population growth of microorganisms
(bacteria).It is these bacteria which make the treatment system operate.

14
V. OWNER MAINTENANCE,CARE AND OPERATION INSTRUCTIONS
Aqua Safe® home wastewater treatment plants have been designed and built by Ecological
Tanks, Inc. to provide long term, reliable and cost-efficient service. Our treatment plants will
operate with a minimum amount of attention.
If service is required,reference the system's DATA PLATES located on the Aqua Safe®control
panel or aerator compressor for the plant's model number,the name, address and phone number
of the local service person that can provide service. The following procedures should be
performed on a routine basis to insure proper plant operation:
DAILY: Check warning light and audible alarm located on the plant's control panel for air
supply malfunction or in system high water indication.if an alarm on condition is observed, it is
an indication of malfunction. First check the electrical circuit providing power to the system to
insure the circuit is closed.Check the aerator compressor to be sure it is operating.Check for over
heating, excessive vibrations and unusual noises. If aerator compressor failure is observed, call
your service provider for service. After a power outage,an alarm condition may exist. Should an
alarm remain on for more than thirty (30) minutes after power is restored,you should call your
local service provider to report the alarm.
WEEKLY: Check the treatment plant for offensive odor.If present call for service.
PERIODICALLY: Check and clean the air filter on aerator compressor.Rinse with warm water
to clean if necessary.Make sure filter is dry and re-install on aerator compressor.
RECOMMENDED: Frequency of solids removal is no more often than every two(2)to five(5)
years. Determination of the need for pumping can be made only by a trained service person by
testing the tank contents and/or effluent. The Aqua Safe®wastewater treatment plant should be
pumped when the settled solids are approximately sixty(60)percent of the total volume.
WARNING -Hydraulic displacement and tank flotation may occur whenever tanks are pumped.
Upon completion of pumping, tank must be refilled with water. Additionally, care should be
taken not to damage internal component parts. A certified Aqua Safe®service technician should
oversee tank pumping.
VI. OWNER'S RESPONSIBILITY
It is the owner's responsibility to operate the Aqua Safe®wastewater treatment plant to the best
of their ability. To keep maintenance to a minimum and insure high effluent quality,the
following items should not be permitted to enter the treatment plant:
1. Strong disinfectants or bleaches,other than small amounts used in day to day house cleaning
and laundries.Recommended detergents are low-sudsing,low phosphates and biodegradable.
Recommended cleaning products arc non-chlorine, non-toxin, non-corrosive and
biodegradable.Anti-bacteria soaps should be avoided.
2. Backwash discharge from any type of water softeners.

15
3. Citrus products,coffee grounds,chemical wastes,paint thinners,oils or grease(such as used
cooking grease), pet shampoo, pet dip disinfectant, pesticides, herbicides, automotive fluids
or any other toxins.
4. Disposable diapers, tampons, sanitary napkins, large quantities of paper products, tobacco
products or similar items. Home brewery waste,strong medicines and antibiotics.
5. Waste material from a garbage disposal is not recommended without the use of a trash trap or
pretreatment tank preceding the Aqua Safe®plant. Food waste represents additional loading
the aerobic treatment unit would have to digest,increasing pump out intervals.
6. The Aqua Safe® wastewater treatment plant is designed for the treatment of domestic
wastewater and nothing else should go into it. During extended period of intermittent or
non-use, such as vacation time, the aerobic bacteria inside the plant will decrease due to no
food in the form of incoming wastewater. The treatment plant will become biologically
stable again soon after the resumption of normal loading. The aerator compressor should be
left on during periods of vacation time. During extended periods of absolute non-use (3
months or longer) the aerator compressor should be removed, cleaned and stored with the
compressor's inlet and outlet sealed.Additionally,the air line piping should also be capped to
prevent debris from entering the air distribution system.
The Aqua Safe® plant will not perform to its fullest capabilities if subject to hydraulic
overloading.This condition exists whenever excessive water,above the plants designed treatment
capacity, is allowed into the plant. Leaking plumbing fixtures or excessive water use may cause
this condition. Hydraulic overload may also occur on wash days,when multiple loads of laundry
are washed in succession.
Ecological Tanks, Inc. is not responsible for the infield operation of our plants. The proper
operation of this wastewater treatment plant depends upon proper organic and hydraulic loading
of the plant. We cannot control the loading of substances in our plants that may upset its
biological balance. We can only provide a complete owner's manual which outlines materials that
should be kept out of the treatment plant. User operation instructions must be followed or
warranties are subject to invalidation.
WARNING! Ants and rodents are destructive to the mechanical and electrical equipment
on wastewater treatment plants. Care should be taken to prevent infestation of ants near the plant.
Damage or destruction of mechanical or electrical equipment by ants or rodents is not covered
under manufacturer's warranty.
Any and all safety requirements such as the electrical wiring,blower operation or plant discharge
concerning the owner, their families, friends, or guests is the sole liability of the owner (see
warranty and service policy).
The electrical control panel contains a schematic for the system. However,the electrical control
panel is sealed and contains no user serviceable parts.Test and alarm silence switches are located
on the outside of control panel.
WARNING! Service to the electrical control panel by a non-qualified person may result
in an electrical shock hazard resulting in serious injury or death. If service is required contact
your local authorized installer representative or maintenance provider.

VII. INSTALLER/MAINTENANCE PROVIDER OPERATION,REPAIR AND
TROUBLESHOOTING
Previous sections in this manual have covered the Ecological Tanks, Inc. Aqua Safe,,system's
functions, specifications, design, proper installation procedures, start up, owner care and
operation instructions. If at this point,you are totally familiar with the material already covered,
you should read it again.
Please pay particular attention to the preceding section titled Owner's Responsibility. This
section covers information critical to the plant's proper loading and function. You will find that
this same information is listed in the Ecological Tanks,Inc.Aqua Sate®Owner's Manual. Your
assurance of the owner's receipt of their manual and the explanation of the manual's contents are
most critical to the plant's proper operation.
You will find, in the following sections of this manual, the Initial Service Policy. It covers
information required of you as a maintenance provider in order for you to provide service in
compliance with NSF/ANSI Standard 40. Additionally, most states have added to the
requirements of this policy. You must know and adhere to all other regulatory agency
requirements concerning mechanical plant service/maintenance standards.Ecological Tanks,Inc.
Aqua Safe® wastewater treatment plants should be inspected every six months for proper
operation. Two years of maintenance is provided as a part of the systems certification
requirements.Ongoing maintenance is usually part of a service agreement maintained between an
owner and maintenance provider. Inspections should include any necessary adjustment of
electrical controls and servicing of the component parts and should include a visual check of
hoses, wires, leads, contacts, cleaning of filters, removal of organic particles, and testing of
alarms to ensure proper function. An effluent quality inspection consists of a visual check for
color,turbidity,scum overflow,and an examination for odors.A mixed liquor inspection may be
necessary if the plant is not performing properly or if offensive odors are present.If any improper
operation is observed which cannot be corrected at that time,the user shall be notified in writing
immediately. This notification shall advise the owner of the problem, if it is covered by the
warranty, if not, the cost related to correcting the problem and estimated date for correction of
said problem.
VH-I. EXAMPLE OF A ROUTINE MAINTENANCE SERVICE CALL
First check the system's control panel for any alarm or failure indication. Check the panel to
insure proper incoming power by testing the incoming power supply. If you know power is
incoming into the control panel, check the circuit feeding the control panel. Next, check the
aerator simply to insure that it is running and then go directly to the treatment plant for an effluent
quality inspection as outlined in the service policy section.At this point pay particular attention to
odors you notice at the plant(or pump tank if applicable). You may notice an earthy smell which
is nothing more than carbon dioxide gas emitted by the aerobic bacteria in the plant. There may
be a sweet smell or no smell at all and that's good. Should you experience an obnoxious odor,
something is wrong.Access the aeration mixing compartment,if necessary,to examine the mixed
liquid and air diffusion system.
Return to the control panel,check for proper functions as outlined in this manual.Also,reference
the troubleshooting guidelines covered on page(). Before servicing the control panel and alarm

17
system,disconnect power to the control panel.
Clean or replace the aerator compressor air filter at this time. If you experienced an offensive
odor when at the plant and heard little or no bubbling, finding a clogged or extremely dirty air
filter may be the problem.Turn on the aerator at this time and check for any air leak between the
aerator and the 3/4" schedule 40 PVC piping. If a leak is detected,effect repair. If a leak is not
detected,the following steps should be taken.
Remove the aerator from the rubber hose connection and install a low pressure gauge between the
PVC piping and aerator. Turn on the aerator and note the pressure. If the line pressure is below
1.5 P.S.I.,then there is a leak between the aerator and the air distribution system in the treatment
plant or the aerator's diaphragm is ruptured. (See the aerator compressor repair section.)
Determine the cause and effect repairs at this time. If a pressure above 3.5 P.S.I. is noted,the air
system piping diffuser assembly is blocked. You can clear the air distribution system's blockage
by charging the air distribution piping with compressed air(no more than 80 P.S.I.). Re-check
the line pressure after any maintenance procedure to the plant's air distribution piping to insure
the correct pressure range. The normal line pressure should be between 1.83 P.S.I.and 2.85 P.S.I.
VI I-2. SCHEDULE OF ROUTINE SERVICE AND MAINTENANCE EVENTS
Routine Inspections 6 months(or
as required by state/local agency)
Air Filters Cleaning/Replacement 6 months
Compressor Diaphragm Replacement 2-3 years
Compressor Replacement 6-8 years
Removal of Residuals from ATU/pre-tank 2-5 years
Replacement of IJV Bulbs(if applicable) 2 years
VII-3. AERATOR COMPRESSOR REPAIR
Linear aerator compressors(See Page 17)are used on all models of the Aqua Safe*wastewater
treatment plants. They provide quiet energy efficient operation. Additionally, rotary vane
compressors(See Page 18)are provided upon request,in-lieu of linear aerator compressors. All
aerator compressors on all models of the Aqua Safe®aerobic wastewater treatment plants run
continuously.
Periodical aerator compressor maintenance will help you to operate the aerator in the optimum
condition and insure longer aerator life. Air filters should be cleaned every six months and
replaced as necessary. Ecological Tanks,Inc.recommends that the air filters be replaced once a
year. The plant's air distribution piping pressure should be measured at least once per year.
Aerator compressors should be operated at the recommended output pressure range which is
between 1.5 and 3.5 P.S.I Aerator life is shortened if operations outside of the specified pressure
ranges occur.
Ecological Tanks, Inc. recommends the diaphragm blocks on linear aerator compressors be
replaced every three years. We also recommend that the vanes be replaced every four years on
rotary vane aerator compressors. Referring to Pages 17-18,note the following text for diaphragm
block and vane replacement procedures:

OSSF Nutrient Reduction Report
for the
Ecological Tanks, Inc.
Aqua Safe
Wastewater Treatment System
Completed by the
Baylor University
Wastewater Research Program
September 15, 2003

Introduction
The following report details the results of extended effluent sampling and evaluation of the performance of
the Aqua Safe wastewater treatment system by the Baylor University Wastewater Research Program to
determine reduction of nutrient levels found in a documented raw influent wastewater stream
Nutrients measured for the report include;Total Kjeldahl Nitrogen(TKN),ammonia,nitrate,nitrite,total
phosphorous and phosphate. In addition,fecal coliform bacteria counts were made on the effluent only.
TKN measures the total organic nitrogen and ammonia nitrogen. TKN plus nitrates and nitrites equal the
total nitrogen in the influent or the effluent. In the decomposition of wastewater,organic nitrogen is
converted into ammonia nitrogen,which in turn is converted into nitrate and nitrite. Nitrite is usually the
wconcentration and is sometimes omitted from the analysis of wastewater lowest but is included in this
study.
The mean,maximum,and minimum values in the raw and treated effluent for each of.these parameters are
reported in tabular and graphic form and may be found in the appendices included.
It is pertinent to note that the evaluation reported here took place during a period of time when the Aqua
Safe system was undergoing an evaluation under the NSF/ANSI Standard 40 certification testing protocol
at the Baylor University Testing and Certification test facility in Waco,'Texas. The test was conducted
from April 15,2002 until December 24,2002 and samples were taken on a weekly basis.
Systems undergoing this test protocol are dosed every day with the full gallons per day dose commensurate
with the system daily rated capacity(in this case the Aqua Safe system was dosed with exactly 500 gallons
per day). Notably the Standard 40 protocol also includes a six-month evaluation period of daily dosing and
four stress sequences of non-ideal dosing conditions,designed to test the system's ability to perform under
adverse conditions. Systems installed in the field under normal conditions are typically considered to
receive somewhat less daily dosing volumes
Executive Summary
Significant reductions occurred in total nitrogen and organic nitrogen.Specifically,phosphorous,
phosphate,TKN and ammonia were reduced but nitrites and nitrates increased as the TKN and ammonia
were converted to nitrates and nitrites. Variations or peaks do not seem to correlate directly with stress
periods and weekly analyses may not provide enough detail to evaluate the specific effects of individual
stresses. However,the stress periods did not appear to impact the treatment system's performance in
overall reduction of nutrient levels in the treatment processes Fluctuations in dosing and influent values
may have had a greater impact on effluent concentrations, Generally,the system reduced nutrients and
average effluent nutrient values were not at levels of health concern.

Fecal Collform
Fecal coliform bacteria are often of concern in evaluating water quality. This study calculated the numbers
of colonies per 100 nil of sample from the effluent only. The numbers varied widely from 10-80000
colonies/I00m1. The average(mean)number of colonies/100m1 was approximately 7000(6999)but the
median was 2200 The wide variability produced a standard deviation of 15c00(15458)coloniest100m1,
which was even greater than the average or median values.Four samples accounted for the high numbers,
These samples include counts of 20000,23200,40000,and 80000 colonies on November 19,October 14,
November 26,and July 8 respectively. Graphic and tabular data for fecal coliform bacteria are included in
the appendices.
Total Kjeldahl Nitrogen(TKN)
The raw influent averaged 28.5 mg/I TKN(mean)and ranged from a low of 2,18 mg/l TKN on April 22,
2002 to a high of 64.6 ntg/I TKN on August 26,2002.Only 4 of 35 samples exceeded 50 mg/I. The
treated effluent averaged 7.25 tttg/I TKN(mean)and ranged from a low of.05 mg/1 TKN on July 22,2002,
to a high of 42.30 nag/I TKN on September 3,2002. The median TKN value for the treated effluent was
2.72 mg/I and although this value is almost 4.5 mg/1 less than the mean value for the treated effluent it is
more than 27 mg/I less than the mean value for the raw influent. The lowest values for the treated effluent
were in May,June,and July 2002 when values were less than 3 mg/i but beginning in August 2002,values
exceeded 10 mg/I on several occasions. The difference between the mean raw influent value and the mean
effluent value is 21.3 mg/1,which represents a decrease of 75%.On only one occasion did the treated
effluent value exceed the raw influent value and that was the day with the highest value for the effluent.
Graphic and tabular data for TKN are included in the appendices.
Ammonia
The raw influent averaged 18 mg/1 of ammonia(mean)and ranged from a low of.05 mg/I ammonia on
April 22, 2002 to a high of 63.50 mg/I ammonia on September 30,2002.Only 1 in 35 samples exceeded 50
mg/1_ The treated effluent averaged 5.3 mg/I ammonia(mean)and ranged from a low of 05 mg'l ammonia
on May13,20,and 28 and June 10 and 17,2002 to a high of'22.50 mg/1 ammonia on September 3,2002.
The median ammonia value for the treated effluent was 95 mg/I and this value is almost 4.3 reglt less than
the mean value for the treated effluent it is more than 15 mg/1 less than the mean value for the raw influent. '
The lowest values for the treated effluent were in May and June 2002 when values were less than 1 mg/1
but beginning in August,values often exceeded 10 mg/1.The difference between the mean raw values for
ammonia and the mean treated effluent values is 12.7 mgil,which is a decrease of over 70 percent.At no
time did the treated effluent values exceed the raw influent values.Graphic and tabular data for ammonia
are included in the appendices.
Nitrate
Nitrate is the byproduct of nitrification of the ammonia.The raw influent averaged 2.1 mg/I of nitrate
(mean)and ranged from a low of.05 mg/1 nitrate on 11 different occasions to a high of 31.50 mg/1 nitrate
on April 15,2002.Only I in 35 samples exceeded 10 mg/I and only 3 values were greater than 5 mg/I The
treated effluent averaged 7,5 mg/I nitrate(mean)and ranged from a low of,21 rug/i nitrate on October 7,
2002 to a high of 22.80 mg/I nitrate on May 5,2002. The median nitrate value for the treated effluent was
5.8 mg/I and although this value is almost 2 mg/I less than the mean value for the treated effluent.it is
almost 4 mg/I greater than the mean value for the raw influent. The lowest values for the treated effluent
were in July,August,and September 2002 when values were less than 10 mg/I but in May,June,October
and November values exceeded 10 mg/I on all but two days The cumulative average decreased steadily
from May through October 2002,then increased slightly in November.The difference between the mean
raw values for nitrate and the mean treated effluent values is an increase of 5.4 mg/1.On only 3 occasions
were the treated effluent values less than the raw influent values and these included the two lowest values
for the treated effluent and the highest value of tlx:raw influent.Graphic and tabular data fot nitrate are
included in the appendices.
Nitrite
Nitrite is the byproduct of nitrification of the ammonia. The raw influent averaged 19 mg/I of nitrite
(mean)and ranged front a low of.05 mg/1 nitrite on numerous occasions to a high of 1.00 mg/I nitrite on
May 28,2002.Only 1 in 35 samples reached 1 mg/1 and only 2 values were greater than .5 mg/I. The
3

treated effluent averaged.13 mg/I nitrite(mean)and ranged from a low of.05 mgll nitrite on numerous
occasions to a high of 1.32 mg/1 nitrite on April 29, 2002. The median nitrite value for the treated effluent
was.05 mg/I and although this value is almost .08 mg/I less than the mean value for the treated effluent it is
more than.1 mg/I less than the mean value for the raw influent. The difference between the mean raw
values for nitrite and the mean treated effluent values is.06 mg/l,which is a decrease of almost 32 percent.
On several occasions the treated effluent values exceeded the raw influent values but only twice was the
difference more than 1 mg/1 Graphic and tabular data fur nitrite ate included in the appendices.
Nitrogen Summary
The TKN is the sum of the ammonia nitrogen and the organic nitrogen. Therefore,the total organic
nitrogen is the mean TKN value minus the mean ammonia value The mean organic nitrogen calculated
for the raw influent is 10.5 rng/l. The total nitrogen is the sum of the TKN,nitrate and nitrite. Therefore,
the total mean nitrogen for the raw influent is 30.8 mg/I The organic mean nitrogen for the treated effluent
is 2.00 mgrl and the total mean nitrogen for the treated effluent is 14.90 mg/1. This is.a reduction of 81%of
the organic mean nitrogen and 52%of the total mean nitrogen.
Phosphorous
The raw influent averaged 8.21 mg/1 of phosphorous(mean)and ranged front a low of 1.16 mg/I
phosphorous on April 22,2002,to a high of 18.30 nu el phosphorous on October 14,2002.Only 2 in 35
samples exceeded 15 mg/I and only 12 values were greater than 10 mgn. The treated effluent averaged 5 9

PREFACE
This report describes the results of the performance evaluation conducted by the Baylor University,
Department of Environmental Studies, Individual On-Site Waste Water Treatment System Testing
and Certification Program, Waco,Texas, with the cooperation of the Brazos River Authority, Waco,
Texas, on the residential wastewater treatment system Aqua Safe, 500 GPD manufactured by
Ecological Tanks,Inc.,in Downsville,Louisiana.
( All laboratory tests were performed at the Waco Metropolitan Area Regional Sewerage System
Treatment plant (WMARSS) operated by the Brazos River Authority (BRA). In-situ tests and
sample collection were performed by Baylor Personnel. All statistical analysis was performed by
( using Microsoft Excel 5.0. Statistical summaries are included in Appendix A.
This report contains results of the testing protocol, a description of the residential wastewater
treatment system, its operation and key process control equipment, and a narrative summary of the
test program, including test location,procedures and significant occurrences.
The purpose of this evaluation is to determine the efficacy of the Aqua Safe 500 gpd residential
f wastewater treatment system for distribution and design application. All phases of this evaluation
were conducted in accordance with the provisions and specifications set forth by NSF International
in `the NSF/ANSI Standard 40, 2000 for residential wastewater treatment systems capable of
producing CIass I effluent.
NSF/ANSI Standard 40,2000
Performance evaluation of residential wastewater treatment systems is achieved within the provisions
of NSF/ANSI Standard 40, 2000 prepared by the NSF Joint Committee on special Processes or
Devices used in Treating Wastewater and adopted by the NSF Board of Trustees, and adopted by the
Baylor University Individual On-Site Waste Water Treatment System Testing and Certification
Program.
The standard is consistent with the methodology established by NSF International in the
development of standards and criteria for special equipment having a bearing on public health and/or
the environment. It provides for uniformity of requirements and interpretation applicable to
processes intended to treat wastewater from individual homes and other sources having similar types
and volumes of liquid wastes.
C
There are five fundamental principles which relate to application of the standard:
t-- a. The standard represents minimum and basic requirements for evaluation.
b. Performance evaluation is independent of design and construction although the
evaluation recognizes structural weaknesses,undesirable noise, and other detriments
to the environment as part of the test results.
{ c. Installation and operation of the equipment is performed according to the
instructions of the manufacturer consistent with actual field installation and use.
•
Aqua Safe Page 3 of 54

Individual On-Site Waste Water Treatment System Testing&Certification Program
d. Appropriate warranties and service provisions must support field applications of the
equipment to enable continuous operation within the demonstrated performance
characteristics of the residential wastewater treatment system or process.
e. Sample collection, preservation and storage, and analytical methods by the testing
agency are in accordance with Standard Methods for the Examination of Water and
Wastewater, Eighteenth Edition, and Manual of Methods for Chemical Analysis of
Water and Wastes, when applicable, and the data produced is certified as a true and
accurate record of performance under the known conditions of the test.
Conformance with the standard is not to be construed as a blanket guarantee of the equipment in all
applications. Rather it is a certification that the residential wastewater treatment system was
appropriately tested and that if the residential wastewater treatment system is manufactured,
installed and maintained as it was tested,documented as reported here in and maintained as required
by the manufacturer,it will usually produce water quality in accordance with the standard.
Residential wastewater treatment systems conforming to NSF/ANSI Standard 40, 2000 are classified
as Class I or Class II residential wastewater treatment systems according to the quality of effluent
produced by the residential wastewater treatment systems during their performance evaluation. Class
I residential wastewater treatment systems must also demonstrate performance consistent with the
odor, oily film and foam requirements of the standard. With the 1978 revision of the standard, Class
I residential wastewater treatment systems must satisfy requirements of the EPA's Secondary
Treatment Guidelines for five day biochemical oxygen demand, suspended solids and pH quality
requirements.
PERFORMANCE EVALUATION
This report is applicable to the residential wastewater treatment system manufactured by Ecological
Tanks, Inc., of Downsville, Louisiana, U.S.A and referred to as the Aqua Safe. This residential
wastewater treatment system is marketed as a complete home aerobic treatment system and has a
rated capacity of 500gallons lM v
P tY per day. This residential wastewater treatment system represented by
the drawings,parts list,and specifications included as Appendix D.

ANALYTICAL RESULTS
During the 26 weeks of operation, the Aqua Safe residential wastewater treatment system produced a (..
treated effluent quality consistent with the Class I requirement. Based on a 500 gallon per day flow,
the Aqua Safe maintained an average CBOD5 effluent of 2.40 mg/L and suspended solids of 2.1
mg/L. On a 90 percentile basis, the residential wastewater treatment system performed with CBODS
effluent between 2.0 and 3.87mg/l and suspended solids between .743 and 6.0 mg/l. The samples
were taken in accordance with and complied to the requirements of the NSF/ANSI Standard 40,
2000 guidelines. The laboratory results summarized and presented in Table II are described herein as
follows:
•
BIOCHEMICAL OXYGEN DEMAND (CBODS)
A. INFLUENT
Based on >148 observations, the range of CBOD5 values was 9.0 to 1071 mg/L. The median
value was 108 mg/L with 50 percent of the values in the range from 75.5 to 223 mg/L C.
B. AQUA SAFE RESIDENTIAL WASTEWATER TREATMENT SYSTEM EFFLUENT
CBOD5, determined in 148 observations, ranged from a minimum value of 9 mg/L to a (. .
maximum value of 1071 mg/L with a median value of 108 mg/L. The interquartile range of -•
values, i.e., the range of variability about the median that lies between the upper and lower
25 percent of the observations, was 75.5 to 223 mg/L. The effluent quality summary, as
shown in Table III, indicates that at least 90 percent of the samples had values greater than
2.0 and less than 3.87 mg/L. The analysis -performed on the quality of the effluent, as
demonstrated in Table V, indicates that the arithmetic mean of all effluent samples collected
in a period of 30 consecutive sampling days has a maximum value of 3.26 mg/L. The '.
arithmetic mean for all effluent samples collected in a period of 7 consecutive sampling days
has a maximum value of 4.21 mg/L. The analysis indicates that the average reduction for
CBOD5 is 98.6%. The values used in determining removal efficiency are presented in Table
IV.

B. AQUA SAFE RESIDENTIAL WASTEWATER TREATMENT SYSTEM EFFLUENT
A median value of 1.6 mg/L was established for effluent suspended solids, based upon 141
observations. The interquartile range was between 1.2 and 2.2 mg/L with 90 percent of the
values being greater than .743 and less than 6.0 mg/L. Table III displays the effluent quality
summary while Table IV shows the removal efficiencies of CBOD5 and SS. As shown in
Table V, the maximum value for the effluent suspended solids is 2.76 mg/L, and the
maximum value for the 7-day mean of effluent suspended solids is 4.47 mg/L. Also
demonstrated in Table V, the effluent does satisfy the suspended solids criteria set forth by
NSF/ANSI Standard 40, 2000, following EPA's Secondary Treatment Guidelines for Class I.
Table IV presents the mean influent and effluent suspended solids values used to calculate
percent reduction accomplished by this residential wastewater treatment system which was
greater than 98.8 %removal of suspended solids.

•
COLOR,THRESHOLD ODOR,OILY FILM,FOAM
NSF/ANSI Standard 40, 2000 specifies limits for Class I effluent with respect to color,
threshold odor, oily film, and foam. Special attention was devoted to these parameters each
sampling day as well as several random checks throughout the 26 weeks, including
weekends. Aqua Safe residential wastewater treatment system effluent was within limits
specified in NSF/ANSI Standard 40,2000:
Aqua Safe Page 9 of 52

T
Baylor University
Individual On-Site Waste Water Treatment System Testing&Certification Program
1. Effluent color was less than 15 units
2. Threshold Odor-non-offensive
3. There was no evidence of oily film or foam.
NOISE
Noise level measurements were taken in accordance with NSF/ANSI Standard 40, 2000 and
LSC, Chapter 13 Section A,6.4.2:(t). The measured level, including background noise, was
within the limits of the NSF/ANSI Standard 40,2000 and the LSC.
STRESS TESTING
Stress loading of the Aqua Safe was conducted as shown by the shaded data in Appendix C
and is designed to evaluate residential wastewater treatment system capabilities and
performance under simulated use conditions of wash day loading, working mother loading,
equipment or power failure, and return from nine days vacation with the typical ypical attendant
shock Ioading. As can be seen from the results depicted in Figure 1 for effluent five day
Biochemical Oxygen Demand (CBOD5) and Figure 2 for effluent Suspended Solids, the C
performance of Aqua Safe was consistent with the effluent quality requirements of
NSF/ANSI Standard 40, 2000 protocol contained in this document. During the seven day
period immediately following each stress condition, the effluent values did remain within the
limits of Class I effluent quality.
TRASH TRAP ISSUE
The issue of a trash trap requires further comment. The Baylor test typically involves
running the residential wastewater treatment system without pretreatment(no trash trap)and,
typically, without post-treatment. The goal of the test is to evaluate the capacity of the
residential wastewater treatment system to treat the incoming wastewater in its most severe
condition. Systems which employ pre- treatment chambers typically are fitted by the
manufacturer with a pass-through pipe in order to by-pass the compartment for the test.
Residential wastewater treatment systems are not tested with a trash trap for several reasons:
L The CBOD strength and low dissolved oxygen levels of the influent sewage means
that a portion of the aerobic bacteria are killed in the(septic)trash trap. Therefore,
normal floc formation indicative of a residential environment is seriously delayed.
2. Influent water is already coarse filtered to remove non biodegradable materials
because these would cause problems for dosing pumps and valves. Such pumps and
valves would not normally be put in a residential installation. However, they are
necessary for the test to control influent rates and times.
3. A trash trap will provide some reduction of CBOD and TSS. The amount depends
on the size of trash trap used. However, operating the test without a trash trap
provides a "worst case scenario."
Some states require the use of a trash trap, independent of this test. Baylor recommends
strongly the use of a trash trap,especially in all cases where a garbage disposal is being used
or may be used. A minimum recommended size for a trash trap is half the daily rated
Page 10 of 52 Aqua Safe

Baylor University
Individual On-Site Waste Water Treatment System Testing and Certification Program
capacity of the residential wastewater treatment system . An absolute minimum size is 1/4
of the residential wastewater treatment systems daily rated capacity. This recommendation
( enables enough capacity to "store" non-biodegradable materials over an extended period of
time (several years) to minimize pumping requirements. However, this size is also small
enough not to interfere substantially with the aerobic performance of the residential
wastewater treatment system or to raise costs excessively. For purposes of the residential
wastewater treatment system certification, a trash trap is treated as an approved "upgrade."
Systems which employ a pretreatment chamber as an integral part of system design
configuration because of cast mold strategies or other considerations, but were not tested
with the pretreatment chamber activated, should not be installed with additional pretreatment
tankage, if the added volumetric capacity represented by the additional tankage would
increase the total net pretreatment volume beyond one-half of the daily rated treatment
capacity of the tested or Model Series System.
`'72
SUMMARY
C:' Overall, the Aqua Safe residential wastewater treatment system performed admirably during
this extended test and under a wide variety of operating conditions. There were no repairs or
maintenance work done on the residential wastewater treatment system during the test
period. During the course of the test, the basic flow system and residential wastewater
treatment system operations were stable and consistent.

I 2.Attention Installers!! The SALCOR Model 3G Unit requires a specific
separate independent 10-15-amp circuit breaker on the main electrical panel.
The Salcor UV Unit circuit breaker should be separate from the circuit
breakers for the pumps, etc.
No other electrical unit should be connected to the Salcor 3G Unit circuit
breaker.
13.The UV Unit operates on 120 VAC single-phase (50 or 60 Hz) power and consumes
30 watts.
14.Bring the power wires and alarm wires into the junction box via the waterproof
conduit connection. Seal the outside of the flexible conduit pipe to the waterproof
connector with Silicone Adhesive Sealant. The installer is responsible for ensuring
that the external flexible wire conduit connection(s) containing
the power and/or alarm wires to the junction box are i y.

block connections on the alarm board. See Figure 4 (Page 10).
The alarm contacts are compatible with external alarm circuit units furnished by
others that use either normally open (N/O) or normally closed (N/C) contacts. Note:
N/O means the contacts are OPEN when there is NO POWER to the alarm board
relay. The contacts are rated for up to 240 volts and up to 2 Amps. Select the common
connection terminal screw and then use either the N/C or N/0 connection terminal
screw that complies with the external receiving alarm circuit requirement.
16.Attach the lid to the junction box with 4 screws.
17.Allow the effluent to start flowing through the 3G Unit.
18.Turn on the circuit breaker at the main electrical control panel. The Green Indicator
Light on the junction box lid should now be shining, indicating that the 3G Unit is
operating properly. The installation is now complete.

IV. MAINTENANCE AND SERVICE
The Salcor Model 3G UV disinfection Unit is designed to provide a long service life;
It is recommended that the UV lamp be replaced every 2 years to insure proper
disinfection.
UV LAMP REPLACEMENT PROCEDURE
1. Turn off the dedicated circuit breaker located on the main electrical control panel
that supplies power to the UV Unit.
2. Remove the electrical junction box from the 4-inch riser pipe by loosening the
junction box to riser pipe setscrew. Then carefully set the junction box aside.
3. Using the white PVC handle connected to the disinfection sub-assembly, lift the
sub-assembly out of the disinfection chamber/riser pipe and set it aside.
4. Loosen the lamp cable cord grip at the top of the white PVC handle so that the
lamp cable can move through the cable grip and thus allow the handle to move
away from the top of the aluminum frame assembly.
5. Unscrew the bottom threaded end of the 1-inch white PVC handle from the upper
end of the aluminum frame assembly. Separate the handle from
the assembly.
6. Disconnect the four pin socket connector attaching the lamp
cable to the UV lamp. Remove the old UV lamp.
7. Use dielectric grease on the boot of the connector. Connect the
4-pin socket connector to the new lamp.
Apply Dielectric Grease to the inside of the boot.
