impact of storm water run-off on efficiency of the effluent treatment plant a case-study.
No full textMonitoring of performance of wastewater treatment systems of an effluent treatment plant is a routine process. However, monitoring is not an easy process when storm water is mixed with wastewater. This is because the mixed water runoff varies significantly in physico‐chemical properties unlike in the case of wastewater alone. The present work evaluates impact of storm water runoff on existing sewage treatment plant situated in an industrial township. Significant dilution effect is observed during monsoon period (June‐September) in the influent and effluent characteristics of sewage. The estimated excess runoff water during these months is mainly due to the rainfall in the region and due to absence of proper control or design for collection of storm water, thereby avoiding the discharge of the storm water into the treatment plant. This has resulted in the reduction of BOD, COD, total nitrogen and total phosphorus, thus decreasing the efficiency of gas generation
