Water is life sustaining element subjected to pollution by human being in the name of industrial development. Global trends such as urbanization and industrialization have increased the demand for fresh water. The developing human societies are heavily dependent upon the availability of water with suitable quality and in adequate quantity for variety of uses. Rapid industrialization is adversely impacting the environment globally. Inappropriate management of industrial wastewater is one of the major environmental problems in India. Many small and medium scale industries cannot afford to have their own effluent treatment facilities which emphasizes on having a common effluent treatment plant to treat the heterogeneous effluent coming out of various sectors. Common Effluent Treatment Plants (CETP) for Textile industry is considered as one of the viable solution for small to medium enterprises for effective wastewater treatment. An effluent treatment plant operating on physical, chemical and biological treatment method with average waste water in flow of 100MLD has been considered for case study. The wastewater was analyzed for the major water quality parameters, such as pH, Chemical Oxygen Demand (COD), Total suspended solid (TSS) and Total Dissolved Solids (TDS). The COD of the treated effluent was reduced significantly, whereas very small reduction was observed in dissolved solids. Most of all the parameters were within the permissible limits of CETP, Pandesara Surat.
