The process of removing pollutants before the water enters a water body is called cleaning of water.
It is known that oils and fats oxidize quickly and harden into a stiff mass. When these get released into closed sewage pipes, they bock the flow of sewage . When these are present in open sewage pipes, fats and oils form an impenetrable film and affect the porosity of water from seeping through and getting filtered
