Unit 4. : Water Quality, Chapter 1: Water Purification and Sewage (Wastewater) Management, • Turbidity of water , When water flows through a river, it contains soil as well as other soluble substances. Particles of such substances are in suspended state in water Therefore, the cleanliness, clarity, transparency i.e. quality of water is reduced. This is called ‘Turbidity of water’, • Different stages of water purification , Pumping of water from a water source, Air mixing in water , coagulation , Flocculation, 5. Sedimentation, 6. Sandstone water filtration (Filtration), 7. Disease Disinfection
