What is a CETP plant?
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.
How reliable is a CETP?
A CETP is said to be more reliable when the values of pollutants in the effluent treated by the plant meet the set discharge standards more often as compared to those of a CETP that frequently exceeds the standards ( Alderson et al., 2015 ). A probabilistic analysis method developed by Niku et al. (1979) has been used to determine the discharge threshold for effluent that would comply with the standard discharge values as prescribed by the governing bodies. This method has been recommended in many handbooks dealing with industrial and sewage effluent ( Metcalf and Eddy, Inc., 2003 ). The model of reliability as developed by Niku et al. (1979) is given below: (1) r = 1 − P F where r is the reliability of plant and P F is the probability of failure.

Why is wastewater treatment important?
Wastewater treatment is an important initiative which has to be taken more seriously for the betterment of the society and our future. Wastewater treatment is a process, wherein the contaminants are removed from wastewater as well as household sewage, to produce waste stream or solid waste suitable for discharge or reuse.
What is wastewater treatment?
Wastewater treatment is a process , wherein the contaminants are removed from wastewater as well as household sewage, to produce waste stream or solid waste suitable for discharge or reuse. Wastewater treatment methods are categorized into three sub-divisions, physical, chemical and biological. 1. Effluent Treatment Plants (ETP):

What is pretreatment in wastewater?
Pre-treatment removes materials that can be easily collected from the raw wastewater before they damage or clog the pumps and skimmers of primary treatment clarifiers, for example, trash, tree limbs, leaves, etc., The influent sewage water is strained to remove all large objects carried in the sewage stream.
What is the primary treatment of sewage?
Primary Treatment: In the primary sedimentation stage, sewage flows through large tanks, commonly called “primary clarifiers” or “primary sedimentation tanks”. The tanks are large enough that sludge can settle and floating material such as grease and oils can rise to the surface and be skimmed off.
