Global Calcium Hypochlorite Market is expected to rise from its initial estimated value of USD 598.96 billion in 2018 to an estimated value of USD 774.81 billion by 2026. Increase in the environment concerns and water consumption is the major factor for the growth of this market.

According to the Central Water Commission, annual water requirement of India is 3,000 billion cubic metres while it receives 4,000 billion cubic metres of rain every year on an average. The problem is the country of 1.3 billion people overuse groundwater instead of rain from the sky.

Groundwater resources are not renewable. So we need to make full use of and protect the only water resources.

And that makes it necessary to use a lot of calcium hypochlorite：

Calcium hypochlorite is an inorganic compound is a white solid that is used for water treatment and as bleaching agent. They are usually used in soft to medium- hard water because they are not soluble in hard water. They are used to kill germs in swimming pools and drinking water. They also act as oxidizing agent and are also used to cleave glycols, α-hydroxy carboxylic acids and keto acids to yield fragmented aldehydes or carboxylic acids.

They are similar to sodium hypochlorite in disinfection properties and are very stable chemical. They are suitable for drinking water and wastewater applications. 

Though meanwhile, they are corrosive and produce chlorine when react with moisture in the air. Waste water systems using Ca(ClO)₂ generally require dechlorinating after disinfection to reduce chlorine discharges to receiving waters.
