For sixteen weeks wastewater treatment in sewage treatment plant at Jalandhar, Punjab was considered for present studies. Sixteen waste water samples were collected at different stages of treatment units and analyzed for the major water quality parameters, such as biological oxygen demand (BOD), chemical oxygen demand (COD), total suspended solids (TSS) and Ammoniacal-N concentration. The performance efficiency of each unit in treating the pollutants was calculated. Percentage removal of BOD, COD, TSS and ammonical-N explains the satisfying overall efficiency of the plant. A mathematical correlation is established between the influent and treated effluent parameters, specifically in relation to the BOD parameter indicated the prior basis and the assessment criteria of the effluent product.
