ii fI l f 7. Supernatant transfer pump: Observe operation of this pump and verify that it is running smoothly and delivering the requared volume within the time span allowed by the process controller (PC). If flow rate is insufficient, PC timing should be adjusted f ` to increase operating time, or the pump should be removed and serviced in accor- dance with instructions in the troublesl noting procedure. If the pump delivers excess volume, the pump should be moved up the standpipe. 8. Sludge return pump: Observe operation of this pump to verify that it is running smoothly and delivering the required volume before shutting off. If the pump is not performing satisfactorily, it should be removed and serviced. 9. Clarifier: Check all support brackets, piping and wiring. At completion of supernatant transfer cycle, wash down the walls, pimps, piping and brackets with freshwater. 10. Electrical control panel: Open box and inspect circuit breakers for burned points and inspect wiring for faulty insulation.,Open one of the breakers to check operation of the alarm signal. Make sure all breakers are left in closed position before closing electrical control box. Check to see that the PC Good and the Batt Good lights are on (Texas Instruments PC).

ROUTINE OPERATIONAL TESTING The owner of any sewage treatment plant is normally required to satisfy local regulatory agencies concerning effluent control. It is Tithe responsibility of the owner to determine local requirements. Some regulatory agencies require periodic or daily reports on plant operation. For good operating control, the owner should have a written record of certain basic data concerning operating conditions. The form shown at the end of this section can be used to record these conditions. The owner`may wish to incorporate these data with other information as required by local regulatory agencies in a daily report log. Weekly procedure for observing and recording information on Form T-6A is as follows: 1. BATCH COUNTER READING: Record€number indicated on counter. 2. NUMBER OF BATCHES: Subtract previous counter reading from current counter reading and record the difference. a 3. DAILY DISCHARGE GALLONS: Calculate as follows and record: (gallons per batch) x (No. of batches) = daily discharge gallons. Number of days between reading. Ei 4. AERATION CHAMBER, COLOR: Open hatch to aeration chamber and remove a well-mixed sample in a one-quart glass jar from a point about 12 inches below the liquid surface level. Visually observe the sample and record approximate color ac- cording to the following code: if BK: Black BN: Brown GN: Green BE: Blue WH: White GY: Grey 4 's
