The basic function of wastewater treatment is to speed up the natural processes by which water is purified. There are two basic stages in the treat- ment of wastes, primary and secondary, which are outlined here. In the primary stage, solids are allowed to settle and removed from wastewater.,
Sewage is liquid waste; most of it is water which has dissolved and suspended impurities. Waste water released by houses,industrial factories and rain water in streets etc are known as sewage water.Mar 15, 2019
Sewage Treatment: The process of removing impurities from waste water before it can be reused or sent to the water bodies is called sewage treatment or cleaning of water. Sewage: The liquid waste which has water as its largest component (along with various types of impurities) is called sewage.
Municipal waste-water which contains large amounts of organic matter is called sewage. Before disposal, hence, sewage is treated in sewage treatment plants (STPs) by the heterotrophic microbes to make it less polluting. Sewage treatment is carried out in two stages.
wastewater treatment, also called sewage treatment, the removal of impurities from wastewater, or sewage, before it reaches aquifers or natural bodies of water such as rivers, lakes, estuaries, and oceans.Feb 19, 2022
Answer: Untreated sewage contains a wide variety of dissolved and suspended impurities. Hence, it is necessary to treat sewage before disposing it in a water body to remove its impurities and to prevent its devastating effect on humans, animals, fishes and birds.
The overall aim of treating sewage is to produce an effluent that can be discharged to the environment while causing as little water pollution as possible, or to produce an effluent that can be reused in a useful manner. This is achieved by removing contaminants from the sewage. It is a form of waste management.
