摘要:Wastewater is being increasingly recognized as an important element in water management in Kuwait,where freshwater is limited and scarce.Currently,huge amount of municipal wastewater in Kuwait receives conventional treatment up to tertiary level.This study evaluates and analyzes the performance and the tertiary treatment process in Jahra sewage plant.The performance evaluation was done based on removal efficiency of BOD(biochemical oxygen demand),TSS(total suspended solids),TN(total nitrogen)and TP(total phosphorus).The results indicated that a significant reduction in TSS,BOD,was observed in tertiary effluent.The results show that the average removal efficiencies of the system for TSS and BOD,were 89%and 66%respectively.However,poor reduction in phosphate and nitrogen contents was noticed with average removal of 6%and 7%respectively.The tertiary effluent satisfied the water quality guidelines and standards applied in Kuwait for restricted irrigation.
