Process Flow Description
Attachment#3— Description of Treatment—Additional Information
OUTFALL NUMBER: 001
A.11.a Description of Treatment
Treatment consists of coarse and fine mechanical bar screens; grit removal; day
tanks; storm flow equalization; five primary clarifiers; three trains in parallel of
activated sludge treatment; four final clarifiers; effluent traveling bridge filters;
ultraviolet disinfection; reuse distribution; sludge thickening; anaerobic
digesters; and sludge dewatering.
B.3. Process Flow Diagram or Schematic
The attached flow schematic SC-1 (Attachment 2) shows the processes of the
treatment facility along with bypasses. The plant is currently permitted to treat
12.0 MGD of wastewater.
Preliminary Treatment:
Wastewater enters the plant through a 36-inch gravity sewer line to enter the
headworks and influent pumping station. The flow entering the headworks
flows through two mechanical screens where the screenings are compacted and
conveyed to a dumpster. Flow from the screens is sent to two vortex grit
removal basins of 30 MGD capacity.
Primary Treatment:
Following preliminary treatment, the wastewater splits between two cells of the
flow equalization day tanks. From here, it is pumped to the distribution boxes
(DB), DB-1, DB-1A, and DB-2A and is distributed to the five existing primary
clarifiers (PC-1 through PC-5). After primary treatment the flow from all of the
operating clarifiers is collected and discharged into DB-5 where it is combined
with the collected RAS flow from all three treatment trains and then is
distributed to the aeration basins.

Secondary Treatment:
The combined flow is combined with RAS and split equally between biological
treatment trains 1, 2 and 3. It goes through anoxic zone and aeration zone with
internal recycle. The activated sludge process is carried out in a series of
rectangular aeration basins and, in trains 1 and 2, is followed by additional round
aeration basins.
Following the aeration basin, flow from the round oxic basins of trains 1 and 2
are combined in DB-9 and split to final clarifiers (FC) FC-1, FC-2 and FC-5. Flow
from train 3 aeration basin is sent to FC-3 at DB-18. A portion of the flow at DB-
18 can be directed to DB-9 to mix with the flows from trains 1 and 2 and feed to
FC-1, FC-2 and FC-5. This portion is determined by a modulating pinch valve that
calculates an input percentage to divert.
Tertiary Treatment:
Combined secondary effluent from all the final clarifiers is sent to filter
distribution structure (FDS) FDS-1 and FDS-2 for filtration. Filtered effluent is
sent for UV disinfection and re-aeration structure where aeration takes place.
The effluent is discharged through a 42" line into Mallard Creek.

Solids Processing and Biosolids Management Plan at Mallard Creek WRF
Mallard Creek WRF is currently operating one 1.0 MG and two .48MG primary digesters with an
average detention time of 40-50 days. The average total solids of raw sludge to the primary
digesters is 3.0-4.0%. Average sludge flow to the primary digesters is between 50-60k
gallons/day. Mallard is currently operating one secondary digester with a volume of 480k
gallons. The average total percent solids of digested sludge at Mallard is 1.5%. For thickening
and dewatering purposes, Mallard uses three Humboldt/Bird and one GEA/Westfalia
centrifuges—two for thickening and two for dewatering. Dewatered solids are belt conveyed
out of the dewatering building into a 24 cu. yard dump truck and taken to a cover storage pad
onsite where they are stored in batches and tested.
The average percent solids of Mallard's cake is 20%. All biosolids produced at Mallard Creek
WRF are Class B biosolids and they are land applied in both North and South Carolina per our
contract with Synagro provided that they pass all required testing and are conforming solids
according to 40 CFR Part 503. All non-conforming solids are hauled by Synagro and landfilled.

Attachment #3

Mallard Basin Inflow and Infiltration (I&I) Reduction Practices
Charlotte Water (CLTWater) has maintained an established evaluation and rehabilitation
program since the early 1990's. The purpose of this program is to restore and preserve
hydraulic capacity, structural integrity, and to reduce corrective maintenance costs by
addressing issues that cause SSOs. This includes maintaining and implementing an on-going I/I
reduction plan.
Multiple construction contracts are continually in place to address these issues. Through
comprehensive SSES efforts, including manhole inspections, smoke testing, CCTV, flow
monitoring, etc., areas are identified for rehabilitation and work orders assigned to a
contractor. The work may include manhole rehabilitation, point repairs, pipe lining and pipe
replacement.
Since July 2003, CLTWater's Rehabilitation Team has inspected in excess of 4,700 manholes,
smoke tested at least 137,000 ft. of pipe, and performed CCTV inspection on more than 15,600
ft. of pipe, resulting in the following 670 manholes rehabbed/repaired, 750 inflow dishes
installed and 3,150 ft. of pipe rehabbed/replaced throughout the collection system. This does
not include similar work performed by CLTWater's Field Operation Division. CLTWater also
implemented a chemical root control program in March 2005 and we continue to maintain and
expand that program.
CLTWater uses flow monitoring extensively to support engineering analyses, to prioritize sewer
improvements, and to evaluate capacity issues and I/I loadings in the major trunk lines in the
system. CLTWater currently has 52 permanent flow meters installed throughout the service
area (4 permanent meters in the Mallard Creek basin) and utilizes temporary flow metering on
an as-needed basis.

Filter, UV and Clarifier Improvements
The purpose of this project is to provide updated and more reliable equipment for the filtration
of final clarifier effluent and for UV disinfection of plant discharge flow. Additionally with this
project, improvements will be made to FC-1, FC-2 and FC-3.
The existing traveling bridge sand filters will be replaced with rotating disc filters with a total
peak flow capacity of 32mgd. These filters will be placed in the footprint of the existing filters
with modifications to the flow routing. Along with the filters the existing UV disinfection system
will be replaced with an updated system also capable of flows of 32mgd. The UV system will be
moved into the footprint previously used by the existing filters with flow modifications.
Along with this project the interior metal structure and operating parts of FC-1, FC-2 and FC-3
will be replaced and upgraded with stainless steel structure and mechanisms to protect against
corrosion and updates will be made to the drive and scum collection systems.
Notice to Proceed Date
July 2019
Final Completion Date
March 2021
Operational Date
March 2021
Generator and Power Distribution Improvements
The purpose of this project is to improve reliability of power and backup generator feed to the
Mallard Creek plant. A new generator building will be constructed with two 3000kW generators
and related switchgear along with a new electrical substation.
The new generators will replace the single active backup generator currently onsite and the
new electrical substation will consolidate the existing power distribution system and make it
more reliable.
Notice to Proceed Date
November 2018

Final Completion Date
June 2020
Operational Date
June 2020
Expansion Project
The purpose of this project is to expand the Mallard Creek plant in order to stay ahead of
increased flow projections in the service basin of the treatment plant. This project is still in its
early stages but may include the expansion or replacement of the influent lift station, screening
removal, primary clarifiers, aeration basins, blowers, final clarifiers and equalization basin.
