The unit treatment processes in the plant include influent screening and a influent pump station. The influent waste stream is split between two extended ' aeration activated sludge plants; with integral clarifiers. The treated effluent from- , the two plants is then combined, and disinfected with UV disinfection. The existing chlorination system was-fie t-m -place as a back up to the UV system. The treated effluent stream is discharged into Cody Creek, a Class C stream in the Yadkin-Pee Dee River Basin. i ATTACHMENT III DESCRIPTION OF SLUDGE MANAGEMENT The sludge that is generated by the wastewater plant is wasted into dual .100 MGD basins. The basins are supernated back to the influent of the plant. The finished sludge is mixed with hydrated lime and sampled to meet requirements of our land application permit No. WQ0003796. The sludge is then land applied by Southern Soil Builders on approved sites.
