Liquid
Waste
Treatment - Agricultural and, industrial operations - alongwith everyday human activities produce liquid wastes, including domestic sewage. These enter into natural water bodies through different routes depending upon the living conditions and habits of local population.
Fortunately, self-purification is an inherent capability of natural waters, based on biogeochemical cycling, But rising population, large scale agricultural operations and industrialisation result in the production of liquid waste on a scale that routinely overwhelms this self-purification capacity of aquatic ecosystems.
