1.5 BRIEF DESCRIPTION OF UNIT OPERATIONS
An overall plan of the plant layout and yard piping is shown in Figures 1.5-1 and 1.5-2.
1.5.1 Preliminary Treatment This structure includes two manual bar screens, and two grit
removal chambers. The primary purpose of the bar screen is to remove rags, sticks and large
solids. The primary purpose of the grit removal chamber is to remove grit and sand. This
lessens the wear on the sludge collecting and pumping equipment that follows. The influent
wastewater flow is monitored at the end of the preliminary treatment as it prepares to enter the
stilling well and influent sampler.
1.5.2 Influent Monitoring Measurement of the plant influent occurs just prior to the
proportional weir at preliminary treatment. A flow sensor transmits signals to the influent
sampler located near the preliminary treatment stilling well. Flow sensing activates the influent
composite sampler. The sampler, which includes a self- contained refrigerator, also may be
controlled by an integral time clock.
1.5.3 Influent Flow Splitter Box This structure receives the flow from the preliminary treatment
unit and divides the flow into two separate "trains" through the WWTP. Oxidation Ditch No.
2 and Clarifiers No. 2 and No. 3, of the original treatment train, will be utilized to handle 2/5
