Effluent treatment plants (ETPs) are common worldwide and a necessary step to improve the quality of wastewater before it is discharged to surface or groundwater and re-enters water supplies. Adequate water resource protection is critical as freshwater systems provide multiple environmental services such as supporting numerous species, supplying water for drinking and irrigation, and assimilating wastes through a biotic/biotic cycling. An effluent treatment plant is a system consisting of mechanical, chemical and biological devices and methods for the purpose of bringing the characteristics of waste water from a manufacturing process, to acceptable standard. Various stages of effluent treatment plants include the following which are influent pit, equalization tank, sequential batch reactor, buffer tank and clear water tank. Wastewater standards are specifications of the biological, chemical and physical quality of the wastewater that is produced by a treatment. These regularly comprise of allowable chemical oxygen demand (COD), Total suspended solids (TSS), Total nitrogen (TN), phosphorus (P), Conductivity, and PH. which indicates the municipal and industrial discharged standards, as well as the by-laws. The effluent treatment plant has a high potential of removing key pollutants and could be used for better treatment of wastewater managed properly
