The method of treatment of industrial and domestic effluent is physical treatment followed by chemical and biological treatment and tertiary treatment to filtration & adsorption column. Sewage water enters to the screen chamber, screen chamber (manually cleaned removable type), should be provided to screen of large floating collection /equalization tank. The effluent from the equalization tank should be made to re-circulate the effluent to enable the content of the effluent screen, and equalization tank, the over ground STP comprises Bio Reactor and Tube Settler. The overflow from the over ground Tube Settler flows by gravity into the Disinfection cum treated effluent holding chamber. ETP cum STP is preferred over to install ETP & STP unit separately. ETP cum STP have common filtration unit along with this benefit of Effluent is undergo biological Treatment & dis-infection. ETP cum STP treatment method is found better where both industrial/process wastewater and domestic/sewage generated because this type of system doesn’t need filtration or tertiary treatment facility for each separate treatment scheme. And the influent after treatment by chemical undergoes biological treatment which improves its water quality.
