In addition to disinfection, what is another use of chlorine in water treatment?

Chlorine is commonly used in water treatment not only for disinfection but also for algal control. Introducing chlorine into water systems can help prevent or manage algal blooms, which can produce harmful toxins and contribute to aesthetic issues like unpleasant odors and tastes. By controlling algae growth, chlorine helps maintain water quality and safety, ensuring that it is suitable for consumption and environmental health.

Chlorine acts as an algaecide; therefore, its ability to effectively inhibit or kill algae is crucial in maintaining the clarity and overall quality of water. It should be noted that while chlorine is not directly involved in processes such as flocculation, mineral enhancement, or pH adjustment, its role in controlling algae is significant in the comprehensive management of drinking water treatment.
