Calcium Hypochlorite

Calcium hypochlorite solution is widely employed in the treatment of swimming pool water. It effectively eliminates bacteria, viruses, and other microorganisms, ensuring clean and safe water. This paper will detail the application method of calcium hypochlorite in swimming pool water treatment.

Composition and Properties of Calcium Hypochlorite

Calcium hypochlorite, a potent oxidizing agent, exhibits strong bactericidal capabilities. It rapidly breaks down in water, forming hypochlorous acid and calcium chloride, which serve as powerful disinfectants. Hypochlorous acid gradually decomposes into harmless chloride ions and calcium carbonate in water, posing no harm to humans or the environment.

Precautions before Cleaning with Calcium Hypochlorite

Preliminary Preparation

Routine Inspection

In addition to adding the calcium hypochlorite solution, regular water quality monitoring and adjustment should occur. By monitoring the calcium hypochlorite content, pH value, and free chlorine concentration in swimming pool water, adjust the calcium hypochlorite solution dosage promptly to maintain water quality within the ideal range. Simultaneously, conduct regular cleaning and maintenance to ensure the normal operation of the swimming pool water circulation system, preventing pollution and bacterial growth.

How to Clean a Pool with Calcium Hypochlorite

Before adding a calcium hypochlorite solution to a swimming pool, dilute the solution with an appropriate amount of water. This ensures even distribution in the pool water, preventing local concentrations that are too high or too low. Add the diluted calcium hypochlorite solution to swimming pool water using an automatic dosing system or manual dosing.

After adding the calcium hypochlorite solution, proper agitation and circulation are necessary to ensure even distribution throughout the pool water. Achieve mixing through the swimming pool water circulation system to guarantee full contact between the calcium hypochlorite solution and the pool water, maximizing the disinfection effect.


In conclusion, the calcium hypochlorite solution is a reliable and widely used method for swimming pool water treatment. It maintains clean and safe swimming pool water by effectively eliminating bacteria, viruses, and other microorganisms. When using the calcium hypochlorite solution for swimming pool water treatment, determine the appropriate concentration, dilute the solution, and evenly add it to the swimming pool. Through stirring and circulation, ensure the solution fully contacts the pool water for the best disinfection effect. Regular monitoring and adjustment of water quality, along with cleaning and maintenance, are crucial steps to ensure swimming pool water quality.
