What is the main purpose of chemical disinfection in water treatment?

The main purpose of chemical disinfection in water treatment is to kill or inactivate pathogens in water. This is a critical process in ensuring the safety of drinking water, as pathogens such as bacteria, viruses, and protozoa can pose significant health risks to the population if consumed. Chemical disinfectants, such as chlorine, ozone, or chloramine, are commonly used in the treatment process because they are effective in eliminating these harmful microorganisms.

Disinfection does not directly improve the taste of water, remove sediments, or enhance mineral content. While taste and mineral content may be affected by other treatment processes, their primary goals do not involve the disinfection of pathogens, which is essential for public health and safety.
