Calcium Hypochlorite (Ca(OCl)₂) is a strong oxidizing chemical widely used as a disinfectant and bleaching agent. It releases chlorine when dissolved in water, making it effective for drinking water purification, swimming pool sanitation, and wastewater treatment. It is usually found as a white or grayish solid with high available chlorine content and longer shelf life than liquid hypochlorite.

Specification:

Chemical Formula : Ca(ClO)2
Appearance : White or off-white granular, powdered, or tablet form.
Odor : Strong chlorine odor.
Available Chlorine Content : 66.6% by weight.
Solubility in Water : Slowly soluble in water, forming hypochlorous acid and
hypochlorite ions (ClO−), which are the active disinfecting
agents. Leaves a slight calcium residue.
pH (1% solution) : 11.40
Stability : More stable than sodium hypochlorite solution, especially in
storage, but can decompose in the presence of heat, moisture,
organic matter, or contaminants.
Storage : Store in a cool, dry, well-ventilated area, in tightly sealed,
non-combustible containers. Keep away from heat sources,
direct sunlight, organic materials, acids, and easily oxidizable
substances. Calcium hypochlorite is an oxidizer and should be
stored separately from other chemicals.
Shelf Life : Generally 1-2 years if stored properly, though available chlorine
content may slowly decrease over time.

Application:

• kills a wide range of bacteria and other micro-organism.
• It can oxidize various organic and inorganic contaminants.
• Easy to transport because of its solid form so best to use in remote or decentralized
system.
• Odor and Biofilm control.
• Effectively
