Which chlorine compound is specifically highlighted for its use in water treatment in the context of generating pH increase?

Calcium hypochlorite is particularly noted for its role in water treatment not only as a disinfectant but also for its ability to raise the pH of water. When calcium hypochlorite dissolves in water, it dissociates and can lead to an increase in pH levels due to the release of calcium ions. This property makes it advantageous in situations where both disinfection and pH adjustment are necessary, providing a dual benefit during water treatment processes.

Additionally, calcium hypochlorite offers a stable form of chlorine that is effective in various water treatment scenarios, including in systems requiring higher pH values for optimal operation, such as in the treatment of certain types of water sources that may require this adjustment. This characteristic sets it apart from other chlorine compounds, which may not have the same effect on pH levels.
