5. Measure the discharge rate from the tanks to the succeeding tank or station. Adjust the return weir to assure the lowest transfer rate into the aeration tank possible within the limitations of the equalization tank volume and ability to equalize post maximum daily flow rates.

6. Fill out maintenance checklist and report deficiencies.

Monthly:

1. Inspect the tank for evidence of proper rolling of mixed liquor suspended solids

(MLSS), fine bubble production from the air diffuser heads, and even diffusion along the length of the aeration tank.

2. Measure the dissolved oxygen in the aeration tank and adjust the blower run intervals accordingly to maintain an average of 1-2 mg/L DO.

3. Conduct a mixed liquor suspended solids (MLSS) settling test of one sample from the aeration basin and one from the effluent from the settling tank. Take readings at five, thirty, and sixty minutes.

4. Inspect the blowers for proper operation. Replace the air filters if dirty, but no less frequently than once every 6-months.

5. Visually check aeration system for even air distribution, with no dead spots.

6. Check oil level in mechanical aerator gear cases. Add or remove as necessary per manufacturer’s instructions.

7. Check oil level in blower gear cases. Add or remove as necessary per manufacturer’s instructions.

8. Check and fix air leaks around base and fitting of blower

9. Check and inspect blower belts for wear and tension.

10. Check bolts and tighten if necessary: foundation, cylinder head, belt guard, etc.

11. Check tension, condition, and alignment of V-belts on blower; adjust or replace as necessary.

12. Check the blower to make sure that belts and drives are free of obstruction and all electrical connection are complete including thermal protection if applicable.

13. Check that effluent weir trough and weir is level and set to the correct elevation and adjust if necessary.

14. Check blowers at a minimum speed and listen for unusual noises.

15. Check the airlift pumps operate continuously and the total pumping rate should be approximately equal to the incoming raw sewage average flow rate.

16. Inspect the sludge digester (also known as the holding tank) where applicable. Pump and clean the tank if settled sludge exceeds 75% of the depth of the tank. Check the airflow in the digester for proper operation.

17. Scrape walls and hoppers of settling tank.

18. Fill out maintenance checklist and report deficiencies.

Blowers:

2. Check cleanliness of quartz sleeves or Teflon tubes. These may be cleaned by mechanical wipers, ultrasonic, or chemicals such as citric acid. Other cleaning agents include mild vinegar solutions and sodium hydrosulfite.

3. Clean noncontact reactor systems with sodium hydrosulfite.

4. UV disinfection system should be pilot tested prior to full-scale operation to ensure that it will meet discharge permit requirements for a particular site.

5. Check that ballast is compatible with the lamps and adequately ventilated to protect it from excessive heating.

6. Check the UV lamp runtime and replace before 9,000 hours of use. Ensure that the quartz tube around the UV lamp is clean and free of grease.

7. Fill out maintenance checklist and report deficiencies

Chlorination

7. Fill out maintenance checklist and report deficiencies

8. Disassemble and clean the various components of the system, such as meters and floats.

9. Inspect and clean valves and springs

10. All tanks, boxes and basins, should be drained, inspected for scale buildup, rust, corrosion, and cleaned as necessary. Any painted surfaces should be inspected for rust and corrosion, cleaned and re-painted if necessary

Wastewater Testing and Operating Parameters

The performing contractor should test all the parameters below and ensure the plant is well within the Goal range

Dissolved Oxygen (DO) Goal: DO = 1.0 – 2.0 mg/L

Turn blowers off, and wait 5 – 10 minutes. Take sample from aeration basin and test immediately after sampling. If over the course of several tests during the 2-day maintenance visit, the DO is consistently too low, increase the amount of time that blowers are running. If the

DO is consistently too high, decrease the amount of time that blowers are running. The wastewater treatment plant contractor will decrease/increase blower run times by small intervals not to exceed 15-minute increments.

Free and Total Chlorine Goal Free Chlorine = 0.5 – 1.5 mg/L

If the plant has a chlorine contact tank, test the effluent being discharged from the plant. If free chlorine residuals do not meet the goals, the wastewater treatment plant contractor will adjust the chlorination rate. If free chlorine readings are consistently above the goal, reduce the amount of chlorination. If the readings are consistently below the goal, increase the amount of chlorination.

Chlorine Contact Time Goal CT = 20 mg/L-minutes

The wastewater treatment plant maintenance contractor will measure the flow rate of the effluent discharged from the plant at peak hour flows and will calculate the disinfection contact time of the plant (time between injection of chlorine and the discharge of the effluent from the plant).

The CT is calculated by multiplying the free chlorine residual (in mg/L) by the contact time. The wastewater treatment plant maintenance contractor will notify the Facility Manager if the CT is significantly less than the goal.

Chemical Oxygen Demand (COD) Goal = 50 mg/L

The wastewater treatment plant contractor will sample the plant effluent for Chemical Oxygen

Demand (COD). If the COD significantly exceeds the goal, the cleanliness of the plant and the effectiveness of the clarifier weirs will be checked and corrected by the contractor.

Total Suspended Solids (TSS) Goal = 30 mg/L

The wastewater treatment plant contractor will sample the plant effluent for Total Suspended

Solids. If the TSS readings consistently exceeds the goal, the contractor will increase the frequency of scraping the clarifier and scrubbing the overflow weirs. The contractor will check for proper operation of the clarifier skimmer.
