The facility has been in operation since 2008. This facility replaced a 0.300 MGD secondary treatment facility. Preliminary Treatment (Numbers 1-4) The wastewater enters the facility via two force mains (one for the Town of Hertford and one for the Town of Winfall). It first passes through mechanical screens with trash washer. It then passes through a parshall flume with flow measurement. It next passes through grit removal consisting of continuously rotating paddle, grit pump and cyclone water separator with conveyor. The trash and grit are removed from the site for landfill disposal. It then enters the influent pump station, consisting of three pumps, that sends it to the oxidation ditches. Secondary Treatment (Numbers 5-7) The secondary system consists of three mechanically aerated oxidation ditches, splitter box and two secondary clarifiers. Tertiary Treatment/Disinfection/Effluent Disposal (Numbers 8-12) The tertiary treatment, after clarification, consists of two parallel disk filters, chlorine injectors and pontact tanks. The disk filters are rated for 10 MGD each, and each contact tank will provide 30 minutes of contact time at that rate. After disinfection, there is the effluent pump station, consisting of three pumps, that sends the treated water either to the Perquimans River, or to the spray field storage tank. After the pump station is sulfur dioxide injection, for de - chlorination. The choice of discharge is based on several conditions. Spray field operation is handled under permit WQQ021289. Sludge Handling (Numbers 13-19) The Settled solids from the clarifiers either returns to the influent pump station as Return Activated Sludge (RAS) or tp the aerobic digester ps Waste Activated Sludge (WAS). The choice is made at the RAS/WAS splitter box. Waste sludge is sent to the aerobic digester, where it is held for at least 30 days under aeration, supernatant is withdrawn and returned to the plant, and then sent to the sludge storage tank to be held until final disposition The sludge can either be sent to the drying beds to be dewatered and disposed of, or sent to the truck loading station and be hauled to approved fields to be disposed of as a liquid. Sludge operations are handled under permit WQ0020239. Town of Hertford WWTP, NC0021849 B3 Process diagram key Sheet 1 I. Mechanical bar screen with debris washer 2.
