Disinfection by-products are commonly formed during which process?

• A. Filtration of water
• B. Disinfection of drinking water
• C. Classifying water pollutants
• D. Storage of treated water

Answer: (B)

Disinfection by-products are commonly formed during the disinfection of drinking water. This process typically involves the use of chemical disinfectants, such as chlorine or chloramines, which are added to eliminate harmful pathogens. During this reaction, organic and inorganic materials naturally present in the water can react with the disinfectants, resulting in the formation of by-products, including trihalomethanes (THMs) and haloacetic acids (HAAs). Understanding the formation of disinfection by-products is crucial because they can pose health risks when present in drinking water at elevated levels. This highlights the importance of balancing effective disinfection practices while minimizing the potential for these harmful by-products. Thus, recognizing the significance of this process helps water operators focus on optimizing water treatment and ensuring public health safety.
