Performance evaluation of the common effluent treatment plant for tanneries at Pammal - Pallavaram Tamil Nadu (India)

The data on flow, BOD, COD, TSS and TDS were collected from the common effluent treatment plant (CETP) for the period from June '96 to November '96. The data were analysed to assess the performance of the CETP in terms of removal efficiency for the above mentioned parameters. The original design of individual units in the CETP were scrutinized for their authenticity. The performance of the individual units in the CETP were analysed by analysing the influent and effluent samples of the respective units. The overall performance of the CETP during the above mentioned months was also analysed. The factors (F/M ratio and θ(c)) affecting the removal efficiency were examined in greater detail. The results were analysed and recommendations were made for the optimum performance of the CETP.
