Effect of Climatic Conditions on Treatment Efficiency of Wastewater Stabilization Ponds at Chokera, Faisalabad

Wastewater management is one of the biggest challenges in world due to increase population and industrialization. In Faisalabad (FSD), wastewater treatment being done through Stabilization Ponds (WSPs) at Chokera, which most economical methods Treatment (WWT). Various parameters were examined check efficiency ponds under diverse climatic conditions. These included Biochemical Oxygen Demand (BOD), pH, Chemical (COD), Turbidity, Copper, Total Solids (TS), Dissolved (TDS) Lead. Six locations selected for monitoring efficiency, inlet outlet plant, influent anaerobic ponds, effluent facultative Pharang drain before after blending with treated sewage. The testing was performed two seasons (i.e. Winter 2015 Summer 2016) Environmental Engineering Laboratory, Department Civil Engineering, University Lahore, Pakistan. BOD5 removal plant found 30.08% winter 51.74% summer against designed value 90% removal. Most not meeting Punjab Quality Standards (PEQS). reasons low are; variation conditions less solar heat intensity, wind speed ceased microbial activity winter), lack funds by government, increased population, mixing industrial sewage domestic attention paid maintain performance Ponds. study carried out assess compare PEQS
