Chlorination is a water treatment process that involves adding chlorine or chlorine compounds to disinfect water. This method effectively kills harmful bacteria, viruses, and other pathogens, making the water safe for drinking and recreational use. It is commonly used in municipal water systems and swimming pools to maintain water quality. In addition to disinfection, chlorination helps control algae growth and improves the overall taste and odor of water. The process can be adjusted to achieve the desired level of chlorine, ensuring that the water remains safe while minimizing any potential health risks associated with chlorine byproducts.
