Calcium hypochlorite with a content of about 65-68% is a granulated product used in various applications. A main application is the disinfection of water in swimming pools and drinking water supply systems, as the product effectively kills microorganisms due to its strong oxidizing effect. In addition, it finds use in industry for the disinfection of surfaces and equipment.

The special suitability of calcium hypochlorite lies in its high availability of active chlorine, which is responsible for disinfection. The chemical mode of operation is based on the release of hypochlorous acid (HOCl), which is formed by hydrolysis of calcium hypochlorite in water. Hypochlorous acid acts as a strong oxidizing agent and inactivates microorganisms by oxidizing proteins and lipids in cell structures.

Compared to other chlorinating agents, such as sodium hypochlorite, calcium hypochlorite offers higher stability and storability. It also has a higher active chlorine content, resulting in more effective disinfection. However, it should be noted that solutions prepared with calcium hypochlorite typically have a high pH, which can be adjusted depending on the application.

In summary, calcium hypochlorite is an effective and versatile disinfectant that is preferred in various applications due to its high chlorine availability and stability.
