What is the main purpose of disinfection in water treatment?

The main purpose of disinfection in water treatment is the selective destruction of pathogenic organisms. Disinfection is a critical step in the water treatment process that aims to eliminate or inactivate harmful microorganisms, such as bacteria, viruses, and protozoa, present in water. These pathogens can cause serious health issues if consumed, so ensuring that drinking water is free from them is essential for public health and safety.

While improving taste, enhancing color, and removing heavy metals are important aspects of water quality, they do not directly relate to the primary objective of disinfection. The primary focus of disinfection is to ensure that the water is safe for consumption by minimizing the risk of waterborne diseases. Techniques such as chlorination, UV treatment, and ozonation are commonly employed to achieve this goal, effectively making the water safe and potable.
