What is the primary function of sodium bisulfate in water treatment?

Sodium bisulfate serves a critical role in water treatment primarily by regulating pH levels and assisting in the removal of chlorine. When added to water, sodium bisulfate effectively reduces the pH, making it more acidic. This is important because maintaining the correct pH balance is essential for optimal water quality and the effectiveness of various treatment processes.

In addition to its pH-regulating properties, sodium bisulfate reacts with chlorine, a common disinfectant used in water treatment. The compound helps to neutralize residual chlorine, making the water safer for consumption and reducing potential health risks associated with chlorine exposure. This dual function of both pH regulation and chlorine removal makes sodium bisulfate a valuable tool in water treatment processes, ensuring that the water is not only safe but also meets the appropriate chemical standards for various applications.
