Abstract—This study evaluates and analyzes the performance and the efficiency of extended aeration sludge process (EASP) utilized in Jahra conventional wastewater treatment plant in Kuwait. The performance evaluation will help for the better understanding of design and operating difficulties of Jahra wastewater treatment plant. For this purpose, weekly samples from Jahra raw wastewater line, aerator effluent stream and clarifier effluent line were collected and analyzed for important wastewater quality parameters. The performance evaluation was done based on removal efficiency of Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Suspended Solids (TSS), Total Nitrogen (TN) and Total Phosphorus (TP). The results indicated that a significant reduction in TSS, BOD, COD was observed in EASP effluent. The results show that the average removal efficiencies of the system for TSS, BOD, COD were 86%, 85% and 81%, respectively. However, poor reduction in phosphate and nitrogen contents was noticed with average removal of 57% and 42% respectively.

Index Terms—Activated sludge process, wastewater, treatment.
