Water is one of the most important components used in all type of industry. It is used in many processes of Industry. It may be used for washing, cooling, Heat Exchanging, condensing the steam etc. But Water used in industry is not totally consumed. Hence, almost all industries generate wastewater from industries that need serious action. So, improper discharge of wastewater can pollute local Environment. In many manufacturing Industries, by-product can be treated as wastewater called “Effluent” should be treated before its release into the environment. The effluent treatment plant is designed to treat the effluent i.e. Wastewater recycling coming from different areas of the plant.
The effluent treatment plant is an outflow of water or gas from a natural body of water, or from a human-made structure. Effluent, in engineering, is the stream exiting a chemical reactor. Effluent is defined as Treated or Untreated Wastewater that flows out of a treatment plant, sewage, or industrial outlet. So this treatment of wastewater i.e. untreated effluent is turned into Treated Effluent with the help of Effluent Treatment Plant (ETP) sometimes it is also called as Sewage Treatment Plant (STP). Clean water then is safely discharged into Environment.
