Segment Insights

Type Insights

The liquid chlorine segment contributed the biggest share of the pool water treatment chemicals market in 2025. Chlorine is the most widely used chemical for the treatment of swimming pool water chemistry because it is very efficient and relatively low cost. Chlorine is the most recognized sanitizer that prevents the development of algae as well as bacteria. It is available in liquid, powdered, and solid forms which are in the form of tablets. Chlorine is a gas utilized in the manufacture of disinfectants such as bleach and other swimming pool products such as sodium hypochlorite. However, it is mostly featured for use with industrial swimming pools where the amount needed is fairly large.

The bleaching powder segment is predicted to grow significantly in the pool water treatment chemicals market over the forecast period. The chlorine present in bleaching powder dissolves in water to form hypochlorous acid and hypochlorite ion which destroy microorganisms and bacteria that are present in the swimming pool facilitating its cleanness. It is widely used for water treatment. The chlorine released by the bleaching powder kills pathogens. Such chlorine remains active in water and ensures that the water does not get infected with pathogens.
