Water treatment is the process of making water safe and suitable for various uses, such as drinking, agriculture, and industrial processes. There are several methods used in water treatment to remove contaminants and impurities, including physical processes like filtration, chemical processes like disinfection, and biological processes like activated sludge treatment.
Some common water treatment techniques include:
1. Coagulation and flocculation: Chemicals are added to water to form floc particles that attract impurities and help them settle out.
2. Filtration: Water is passed through filters to remove particles, microorganisms, and other impurities.
3. Disinfection: Chemicals like chlorine or UV light are used to kill harmful bacteria and pathogens in the water.
