What does a chemical feed pump do to the water?

The function of a chemical feed pump is vital in water treatment processes, particularly in maintaining water quality for various applications. When considering the method by which the pump interacts with the water, it specifically adds substances that help adjust certain chemical properties.

The reason the choice regarding adjusting pH by adding acid or sodium bisulfate is correct is that pH balance is critical in water treatment. If the water's pH is too high (alkaline), adding acid will lower it; conversely, substances like sodium bisulfate also help to manage pH levels effectively. These adjustments are necessary to ensure the optimal conditions for processes such as disinfection, corrosion control, and overall system performance.

In contrast, while chlorine is indeed a chemical added to water for disinfection, it is more specific to another aspect of water treatment. The removal of large particles pertains to filtration processes rather than chemical dosing. Similarly, increasing water temperature does not typically involve the function of a chemical feed pump but rather might engage with heaters within a water system. Understanding these roles helps clarify the specific purpose of chemical feed pumps in water systems.
