What is the main characteristic of the breakpoint chlorination?

• A. It minimizes chlorination byproducts
• B. It ensures maximum pathogen removal
• C. It achieves seasonal water clarity
• D. It reduces operational costs

Answer: (B)

Breakpoint chlorination is a critical process in water treatment that focuses on ensuring maximum pathogen removal. This method involves adding chlorine to water until a point is reached where all the ammonia and organic matter are oxidized, allowing the free chlorine to act more effectively against pathogens such as bacteria and viruses. By reaching this breakpoint, the chlorine concentration becomes high enough to eliminate these contaminants efficiently, which is essential for maintaining safe drinking water. This process also helps to generate chloramines, which, while useful for maintaining residual chlorine levels in the distribution system, are not as effective at disinfecting as free chlorine at higher concentrations. Therefore, utilizing breakpoint chlorination is vital in achieving optimal pathogen removal in treated water, ensuring that it meets health standards and is safe for consumption. Other options relate to various aspects of chlorination and water treatment but do not directly address the primary function of breakpoint chlorination with respect to pathogen removal.
