What is the main function of disinfection in the water treatment process?

The main function of disinfection in the water treatment process is to reduce microbial contamination. This is a critical step in ensuring that water is safe for consumption and meets health standards. Disinfection involves using chemical agents, such as chlorine or ozone, or physical methods, such as UV light, to kill or inactivate pathogenic microorganisms, including bacteria, viruses, and protozoa.

By effectively targeting these harmful microorganisms, disinfection plays a vital role in preventing waterborne diseases and protecting public health. This process does not primarily focus on enhancing water clarity, adding taste, or improving mineral balance, as those functions are related to other aspects of water treatment. Clarity is typically addressed through processes like coagulation and filtration, while taste adjustments may involve activated carbon or other treatment methods, and mineral balance is usually managed through blending or the addition of specific minerals during treatment.
