What purpose does chlorination serve in water treatment?

Chlorination is a critical process in water treatment primarily aimed at the destruction of pathogens. This is essential for ensuring the safety of drinking water, as it helps eliminate harmful microorganisms such as bacteria, viruses, and protozoa that can cause diseases. By introducing chlorine to the water, the chemical reacts with the cellular structures of these pathogens, effectively neutralizing them and making the water safe for human consumption.

While enhancement of taste, prevention of corrosion, and removal of dissolved gases may be relevant factors in the broader context of water treatment and quality, these purposes do not define the primary objective of chlorination. The primary concern in water treatment processes is the protection of public health through effective disinfection, making the destruction of pathogens the most pertinent and essential aspect of chlorination.
