An Effluent Treatment Plant (ETP) is a process for treating waste water in textile, chemical, and pharmaceutical industries, where the water is contaminated to an extreme. Some of the many pollutants that can be treated by it include organic and inorganic matter, oil, grease, heavy metals, suspended particles, and much more. By using it, fresh water is not unnecessarily used for production purposes or commercial activities. It is an effective way to prevent water pollution.
