An effluent treatment plant (ETP) is a facility used to treat wastewater that is produced by industries or other sources such as agriculture. The treated water is then either reused or released into the environment. ETPs are designed to reduce contaminants in the wastewater before it is discharged into nearby bodies of water. The process involves a combination of physical, chemical, and biological treatments. The goal of an ETP is to reduce the number of pollutants in the wastewater so that it can be safely discharged back into the environment.
And it is designed to treat wastewater that has been contaminated by industrial or commercial processes. It is used to reduce the levels of pollutants such as suspended solids, biochemical oxygen demand, and chemical oxygen demand in wastewater. The treatment process typically includes physical, chemical, and biological processes to remove contaminants, and then the treated wastewater is discharged into a receiving water body.
