Calcium chloride is added to fresh water because of its ability to improve the hardness of
water and Calcium chloride is a good source of Calcium ions.
Power generation uses calcium chloride for boiler water treatment, cooling water treatment,
and wastewater treatment. It helps prevent scale formation, corrosion, and microbial growth
in industrial water systems.
Calcium chloride is commonly used in municipal water treatment plants for many different
purposes, including pH maintenance, alkalinity enhancement, and corrosion control. This
chemical can stabilize water and improve the quality of drinking water. In municipal water
distribution systems, calcium chloride is added to inhibit corrosion of metal pipes and
infrastructure, prolonging their lifespan and ensures water quality.
