title: Performance evaluation of common effluent treatment plant for tanneries at Pallavaram CETP.
abstract: The Pallavaram Tanners Industrial Effluent Treatment Company Limited has been a forerunner in ensuring cleaner and safe environment. The project was implemented by a company formed by the tanners of the Pallavaram area. Tamil Nadu Pollution Control Board (TNPCB) was the counterpart of UNIDO and took the overall responsibility for implementation of the project. The present study has been undertaken to evaluate performance efficiency of the treatment plant. Water samples were collected at different stages of treatment units and analysed for the major water quality parameters, such as pH, biological oxygen demand (BOD), chemical oxygen demand (COD), total suspended solids (TSS) and total dissolved solids (TDS). The performance efficiency of each unit in treating the pollutants was calculated. The generated data presented evidence to that the common effluent treatment plant has been working with the norms of TNPCB and meeting the discharge standard limits.
