Comparative studies for the treatment of industrial effluents employing advanced processes: towards enhancement of environmental performance

Abstract The investigation was inspired by the declaration of critically polluted industrial zones in India. It also reported that most Common Effluent Treatment Plants (CETPs) are non-compliant due to higher COD values discharge than regulatory norms. Furthermore, literature has not efficacy advanced wastewater technologies for real effluent. Thus, this research focused on field trials scalable Vatva Industrial Estate (VIE), Ahmedabad. potential physico-chemical and treatment processes explored applicability treatment. research, three industries from each sector, i.e., textile processing, dyes, dye intermediates, a total nine different were chosen. A sufficient volume effluent collected industry detailed investigations. initial loading observed range 68 7074, 30 896, 100 1541 kg COD/day respectively, with significant variation qualitative profiles. treated electrocoagulation Fenton's reagent batch scale reactors. reactors both 1L size. results treatability studies represented performed better process selected study. This provides insight improvement environmental performance individual general CETPs particular.
