Medical Conditions - Purification Of Water

Purification of water is a process of removing undesirable chemicals, contaminants, and gases from the water. Water purification is done by physical processes like filtration, sedimentation, and distillation. The chemical processes involved in water purification are flocculation, chlorination, and electromagnetic radiation by ultraviolet light. Purification of water is also done by a biological process using active carbon and filters.
