Calcium Hypochlorite 70% Granular

Calcium Hypochlorite for Water Disinfection and Sanitation

Calcium Hypochlorite is a solid chlorine compound used to disinfect water and surfaces. Calcium hypochlorite releases chlorine when it dissolves, and that chlorine kills bacteria, viruses and algae. Because it is a dry solid, it stores and transports more easily than liquid bleach.

We stock HI-CLEAR Calcium Hypochlorite, granular, from Dodhia Chemtex Pvt. Ltd. The label states 70% calcium hypochlorite as the active ingredient, with UN number 1748. Wisdo Merchants Chemical Division delivers it across Kenya and East Africa from Industrial Area, Nairobi.

Applications of Calcium Hypochlorite

Swimming Pools

Pool operators use it to keep water free of bacteria and algae. They dissolve the granules in a bucket of water first, then add the solution to the pool. Additionally, it is used for shock treatment after heavy use.

Drinking Water Treatment

Water utilities, institutions and boreholes use it to disinfect drinking water and storage tanks. It typically follows coagulation and filtration, for example with our PAC coagulant powder. Browse our water treatment chemicals.

Sanitation and Disinfection

Hospitals, food plants and public facilities use chlorine solutions made from it to sanitise floors, drains, toilets and equipment. See our cleaning and disinfection chemicals.

Wastewater and Industrial Uses

Effluent plants use it to disinfect treated water before discharge. Textile mills also use hypochlorite as a bleaching agent.

Safety and Handling

Calcium hypochlorite is a strong oxidiser and corrosive. Handle it with great care.

• Keep out of the reach of children, as the label states.
• Fire risk: It may intensify fire. Keep it away from fuels, oils, organic materials and heat.
• Toxic gas: Contact with acids releases toxic chlorine gas. Never mix it with acids, ammonia or other cleaning chemicals.
• Burns: It causes severe skin burns and eye damage. Wear goggles, gloves and protective clothing.
• Dissolving: Always add the granules to water, never water to the granules.
• Environment: It is very toxic to aquatic life. Prevent spills from entering drains or waterways.

Always read the Safety Data Sheet before use.

Storage and Shelf Life

Store drums tightly closed in a cool, dry, well-ventilated area, away from direct sunlight and heat. Keep them separate from acids, fuels, organic materials and other chemicals. Moisture and heat cause it to lose strength, so reseal drums immediately after use.
