The Reference Standard in UV
Proven, chemical -free disinfection from the industry leader
UV is the most effective, safe and
environmentally friendly way to disinfect
wastewater. It provides broad-spectrum
protection against a wide range of
pathogens, including bacteria, viruses
and chlorine -resistant protozoa
(such as Cryptosporidium and Giardia).
The Trojan UV3000PIusTI is one of the
reasons why UV treatment is now a
favored technology in wastewater
treatment. This highly flexible system
has demonstrated effective and reliable
performance around the world. It is well
suited to wastewater disinfection
applications with varying flow rates and
influent. These include particularly
challenging influents such as combined
sewer overflows, primary and tertiary
wastewater reclamation and reuse.
The proven infrastructure of the
TrojanUV3000Plus has been
continuously refined to enhance friendly
operation. The result is more
dependable performance, simplified
maintenance and maximized UV lamp
output at end -of -lamp life. The
TrojanUV3000Plus also incorporates
innovative features to further reduce
operation and maintenance (0&M)
costs, such as variable output electronic
ballasts and our revolutionary
ActiCleanTm automatic chemical/
mechanical sleeve wiping system.

TROJAN CIV3000PLUSTI
Designed for efficient, reliable performance
System Control Center (SCC)
The SCC monitors and controls all UV functions
to ensure proper disinfection performance while
conserving power and extending lamp life. The
microprocessor -based Touch Smart Controller
is housed in a small panel and features a user-
friendly, touch -screen Human Machine Interface
(HMI) along with Modbus Ethernet or Modbus
RTU for SCADA connectivity. Along with dose -
pacing control, the Touch Smart controller logs
data for trending and analysis (flow, power,
UVT, UV intensity and dose). A Programmable
Logic Controller (PLC) can be supplied for larger
systems (with more than 2 channels) for the
advanced controls required for multiple channel
operation and automatic slide/ sluice gate control.
R
Extensive alarm reporting system ensures fast
and accurate diagnosing of system process
and maintenance alarms. Programmable control
software can generate unique alarms for
individual applications.
Power Distribution Center (PDC)
The PDC powers each bank of modules.
Its ergonomic, angled design provides
easy access to module power cables and
hoses for the ActiClean cleaning system.
The robust stainless steel enclosure
is mounted across the channel, with
module fuses and interlock relays visually
aligned with module receptacles for fast
diagnostics. Modules are individually
overload -protected for safety. Like all
Trojan UV3000PI us components, the PDC
can be installed outdoors and requires
no shelter, Heating, Ventilation or Air
Conditioning (HVAC).
UV Intensity Sensor
The UV intensity sensor continually
monitors UV lamp output. The ActiClean
system automatically cleans lamp and
sensor sleeves simultaneously.
q�
U
M
Electronic Ballasts
The variable -output (60 - 100% power)
electronic ballast is mounted in its
own TYPE 6P (IP67) rated enclosure
within the module frame. Features "quick
connect" electrical connections. Cooling
is by convection.
2

ActiClean Cleaning System
The system consists of two components:
1. Hydraulic System
Center (HSC)
T The HSC actuates the ActiClean
cleaning system, and is mounted
close to the channel in a stainless
steel enclosure. It contains
the pump, valves and ancillary
equipment required to operate the
cleaning system and links to the
extend/retract hoses of the module
wiper drives via a manifold located
on the underside of the PDC.
UV Modules
2. ActiClean
Wiper Assembly
A submersible wiper drive on
each UV module drives the wiper
carriage assembly along the module.
Attached wiper canisters surround
the quartz sleeves, and are filled with
ActiClean-WW Gel. The gel uses
food grade ingredients and contacts
the lamp sleeves between the two
wiper seals. Cleaning takes place
while the lamps are submerged and
while they are operating.
UV lamps are mounted on modules
installed in open channels. The lamps
are enclosed in quartz sleeves, and
positioned horizontally and parallel
to waterflow. A bank is made up of
multiple modules placed in parallel. All
ballast and lamp wiring runs inside the
module frame.
Water Level Sensor
The system includes an electrode low
water level sensor for each channel.
If effluent levels fall below defined
parameters, an alarm will be activated.
JMi
Water Level Controller
A fixed weir, motorized weir gate, or
Automatic Level Control gate (shown),
is required in the channel to maintain
the appropriate water level over the
lamps. Trojan engineers will work with
you to select the appropriate level
control device for your application.

2. The measurement of water levels shall be made prior to purging the wells. The depth to water in each well shall be measured from the surveyed point on the top of the casing. The measurement of
pH shall be made after purging and prior to sampling for the remaining parameters.
3. The measuring points (top of well casing) of all monitoring wells shall be surveyed to provide the relative elevation of the measuring point for each monitoring well. The measuring points (top of
casing) of all monitoring wells shall be surveyed relative to a common datum.
4. Volatile Organic Compounds (VOC) - In November only, analyze by one of the following methods:
a. Standard Method 6230D, PQL at 0.5 µg/L or less
b. Standard Method 621OD, PQL at 0.5 µg/L or less
c. EPA Method 8021, Low Concentration, PQL at 0.5 µg[L or less
d. EPA Method 8260, Low Concentration, PQL at 0.5 µg/L or less
e. Another method with prior approval by the Water Quality Permitting Section Chief
Any method used must meet the following qualifications:
a. A laboratory must be DWR certified to run any method used.
b. The method used must, at a minimum, include all the constituents listed in Table Vlti of Standard Method 6230D.
c. The method used must provide a PQL of 0.5 µg/L or less that must be supported by laboratory proficiency studies as required by DWR. Any constituents detected above the MDL but below
the PQL of 0.5 µg/L must be qualified (estimated) and reported.
5. If any volatile organic compounds (VOC) are detected as a result of monitoring as provided in Attachment C, then the Wilmington Regional Office supervisor, telephone number [phone],
must be contacted immediately for further instructions regarding any additional follow-up analyses required.
6. If TOC concentrations greater than 10 mg/L are detected in any downgradient monitoring well, additional sampling and analysis must be conducted to identify the individual constituents comprising
this TOC concentration. If the TOC concentration as measured in the background monitor well exceeds 10 mg/L, this concentration will be taken to represent the naturally occurring TOC
concentration. Any exceedances of this naturally occurring TOC concentration in the downgradient wells shall be subject to the additional sampling and analysis as described above.
7. Monitoring wells shall be reported consistent with the nomenclature and location information provided in Figure I and this attachment.
