What is the primary benefit of using chlorine in water treatment?

The primary benefit of using chlorine in water treatment lies in its effectiveness in killing bacteria and pathogens. Chlorine is a well-known disinfectant that has the ability to eliminate a wide range of harmful microorganisms present in water. When added to water, chlorine reacts with organic substances and provides a residual effect that continues to disinfect as water flows through the distribution system.

This property is crucial for ensuring safe drinking water, as it helps prevent waterborne diseases by destroying potentially harmful bacteria, viruses, and protozoa. By maintaining a certain level of chlorine in water systems, water authorities can ensure ongoing protection against microbiological contamination, which is vital for public health.

While chlorine may have some impacts on pH levels and can interact with other substances in the water, its primary and most critical role in water treatment is its ability to disinfect and ensure water safety by targeting pathogens effectively.
