<P> Water purification is the process of removing undesirable chemicals , biological contaminants , suspended solids and gases from water . The goal is to produce water fit for a specific purpose . Most water is disinfected for human consumption ( drinking water ) , but water purification may also be designed for a variety of other purposes , including fulfilling the requirements of medical , pharmacological , chemical and industrial applications . The methods used include physical processes such as filtration , sedimentation , and distillation ; biological processes such as slow sand filters or biologically active carbon ; chemical processes such as flocculation and chlorination and the use of electromagnetic radiation such as ultraviolet light . </P>
