What can excessive chlorination lead to in water treatment?

• A. Increased water pressure
• B. Formation of harmful disinfection byproducts
• C. Reduced water quality
• D. Increased water temperature

Answer: (B)

Excessive chlorination in water treatment can lead to the formation of harmful disinfection byproducts. When chlorine is added to water for disinfection, it can react with organic matter present in the water. This reaction results in the creation of various byproducts, some of which may be harmful to human health. Examples include trihalomethanes (THMs) and haloacetic acids (HAAs), both of which are regulated due to their potential health risks. Effective water treatment requires balancing sufficient disinfection while minimizing these byproducts, making it essential to monitor chlorination levels closely to avoid excessive use that could lead to adverse consequences. Understanding this aspect helps water treatment operators implement safer chlorine dosing practices and ensure overall water quality.
