Abstract	Wastewater treatment and repurposing will be pivotal for growing economies as demand for water increases. A sustainable approach toward economic development in India would be treating industrial wastewater for agricultural applications, reducing overall water consumption, and feeding one sector of the Indian economy with effluent from another. To achieve this, a cost-effective and sustainable treatment process needs to be developed. This paper provides a comprehensive analysis of the available methods and equipment for wastewater treatment through a brief literature review. A four-stage treatment was considered, including pretreatment, primary and secondary chemical treatment, and post treatment. The overall process features screening, oil skimming, coagulation, flocculation, sedimentation, aeration, and gravel filter. The most important specifications suitable for India include using spent poly-aluminum chloride as a coagulant and flocculant (CPCB, 2022) and using vertical shaft aerators (Drewnoski, et. al., 2019) and high-efficiency blowers (Bell, et. al., 2011) in the aeration process.
