Which is not a primary purpose of chlorination in water treatment?

Chlorination in water treatment primarily serves several critical functions, with the primary goal being the elimination of pathogenic microorganisms. The introduction of chlorine into the water effectively neutralizes bacteria and viruses that can pose health risks, making it a vital step in ensuring safe drinking water. This method is widely utilized because chlorine is a powerful disinfectant capable of inactivating a broad range of pathogens.

Additionally, chlorination contributes to the residual protection of water by maintaining a certain level of chlorine in the distribution system. This residual helps to prevent the regrowth of microorganisms as the water travels through pipes to homes and businesses, establishing a barrier against contamination.

Improvement of taste, while not its primary function, can be a secondary benefit. Chlorination can diminish unpleasant odors and taste associated with some water sources, thereby enhancing overall consumer acceptance, although the taste of chlorine itself can be off-putting for some individuals.

The option that is not a primary purpose of chlorination is related to reducing chlorine demand. Chlorine demand refers to the amount of chlorine that is consumed by the water and its contaminants, including organic materials and ammonia. While managing chlorine demand is an important aspect of the water treatment process, it is not a primary purpose of chlorination itself; instead, it is
