The facility is permitted for 0.300 mgd and has an average daily flow of 0.170 mgd. The facility receives wastewater flow from the Town of Kenansville. The WWTP consists of the following major units: • Dual manual bar screen • Dual grit troughs • Dual oxidation ditches — 187,500 gallons each Dual secondary clarifiers — 48,500 gallons each • Disinfection — chlorination • Dechlorination • Two sludge digesters • Sludge storage tank • Sludge drying beds • Flow meter • Standby electrical generator Preliminary Treatment As the flow enters the facility it is screened. The physical process of wastewater treatment begins with screening out large items that have found their way into the sewer system, and if not removed, can damage pumps and impede water flow. After passing through the screens, the flow enters the grit troughs where sand is settled. Excessive sand entering the treatment process can cause excessive wear on pump parts, clog lines and valves, and deposit on the bottom of the basins. Secondary Treatment From preliminary treatment the influent flows to the oxidation ditches for biological treatment. The oxidation ditches have a capacity of 187,500 gallons each. Each ditch is aerated by a single 42-inch diameter magna rotor. The rotor has two purposes. First, the rotor supplies the oxygen necessary for biological treatment in the form of mechanical aeration and secondly, the rotor imparts the velocity necessary to mix and move the wastewater around the ditch to the point of discharge. The primary function of the oxidation ditches is to provide the necessary environment and time to encourage the breakdown of any organic material (and the growth of the bacteria), as well as ensure there is enough time for the organic material to be broken down. This process is managed to offer the best conditions for bacterial growth. DocuSign Envelope ID: 388954A4-129D-4F8A-8057-419404562877 Water is discharged from the two oxidation ditches into a splitter trough which divides the water into two secondary clarifiers. Quiescent conditions in the clarifiers provide an environment for the separation of solids and water. The incoming "mixed liquor" is discharged around the periphery of each clarifier near the water surface via a narrow raceway. The settled activated sludge is returned to the oxidation ditches (Return Activated Sludge or RAS) to increase the bacterial concentration, help in propagation, and accelerate the breakdown of organic material. The RAS pump rate is set to maintain a sludge blanket of approximately three feet in the clarifier. To maintain the proper amount of activated sludge in the oxidation ditch, a portion of the settled sludge will be removed (Waste Activated Sludge or WAS) from the treatment process by pumping a portion of the RAS to the sludge digester. Disinfection The clear effluent from the clarifiers flows to the chlorine contact basin. A chlorine solution is added to the head of the basin and the basin provides the needed contact time for disinfection. The disinfected effluent is aerated prior to discharge from the chlorine contact basis. The effluent flows from the site of the "new" plant to the site of the "old" plant. The flow enters the dechlorination contact chamber to dechlorinate the wastewater prior to its discharge to Grove Creek. Solids Handling Wasted activated sludge is pumped to two aerobic digesters at the "old" plant. The aerobic digesters provide long term holding and stabilization of the solids removed from the treatment process. Stabilized sludge may be stored in the sludge holding tank.
