Case Study 1 Zeekoegat WasteWater Treatment Plant 4.1 PLANT OVERVIEW Zeekoegat WWTP is located upstream of Roodeplaat Dam on the Pienaars River. The plant treats mainly domestic wastewater with small industrial contri bution from Moreletaspruit and Hartebeestspruit. The remainder of wastewater from these areas is treated at Rooiwal WWTP. Screened and degritted raw wastewater is split between two modules which co nsist of primary settling tanks (PSTs), balancing tank, an enhanced biological phosphorus removal (EBP ) activated sludge bioreactor, secondary settling tanks (SSTs) and final effluent disinfection. Module 1 was commissioned in 1 with an original design capacity of 3 Ml/ average dry weather flow (ADWF). The module was upgraded in 2 and now has rated capacity of 4 Ml/ ADWF. second module with rated capacity of 4 Ml/ AD WF was commissioned in June 2. new sludge handling and treatment facility consisting of fermenter, anaerobic digesters, sludge dewatering and sludge liquor treatment facilities was commissioned in 2. Final effluent from the plant is discharged to Roodeplaat Dam. 4.2 TREATMENT PROCESS DESCRIPTION Figure 4-1 shows an aerial photo of Zeekoegat WWTP. brief description of the main process units is given below.
