What is the significance of measuring "available chlorine" in water treatment?

• A. It determines the rate of flow in a water system
• B. It indicates the concentration of chlorine in chlorinated compounds
• C. It measures the pressure in a water supply system
• D. It assesses the temperature of the water

Answer: (B)

Measuring "available chlorine" in water treatment is crucial because it indicates the concentration of chlorine that is available to disinfect the water effectively. Chlorine is commonly used in water treatment processes to kill harmful microorganisms, and understanding the concentration of available chlorine helps operators ensure that there is an adequate amount present to meet disinfection goals. Available chlorine refers specifically to the chlorine that is actively engaged in the disinfection process at any given time, as opposed to chlorine bound in compounds that may not exert a disinfecting effect. This measurement is important for maintaining water quality and ensuring that drinking water is safe for consumption. In the context of water treatment operations, this information is essential for dosing chlorine correctly, allowing for adjustments based on factors such as water turbidity, organic load, and chlorine demand. Proper management of available chlorine levels contributes to the overall effectiveness of water treatment systems and public health protection.
