Description Common effluent treatment plants (CETPs) have been installed and are in operation at numerous industrial clusters
throughout India. They serve to reduce effluent treatment cost, provide better collective treatment, and reduce land cost for
small-scale industrial facilities that cannot afford individual treatment plants. Optimum working conditions for treatment of
effluent to be at par with discharge standards is a major mandate for any CETP. In this study, the reliability and removal
efficiencies (REs) of a CETP in the industrial area of Maharashtra State in India were examined. An established methodology was
adopted to determine the effectiveness of the CETP in terms of biochemical oxygen demand (BOD), chemical oxygen demand
(COD), total suspended solids (TSS), and oil and grease (O&G) concentrations. The CETP’s compliance with respect to design
standards and its operation were studied in detail. This paper highlights the results of RE and the coefficient of determination (R2)
values obtained from the CETP data, estimates the pollutants removed at the highest and lowest rates over a period of time, and
highlights the reasons for problem areas along with remedial measures. It was observed that, except O&G, all the parameters
(BOD, COD, and TSS) showed fluctuations in removal efficiencies and their reliabilities. This situation can be improved by
releasing effluent containing hydraulic and organic loading to the CETP as per standards and optimizing treatment processes,
especially primary clari-flocculators and aeration tanks, both of which are important units of any CETP.
