Water Treatment
Calcium chloride is used by the petroleum, metalworking, laundry, textile, and food processing industries to treat wastewater since it allows for the easy removal of oil droplets and other contaminants.
Where To Use
Calcium chloride is used in wastewater treatment to remove impurities. The petroleum, metalworking, laundry, textile, and food processing industries add calcium chloride to oily waste streams, which causes oil droplets to float to the surface for easy removal by skimming. Calcium chloride reacts with fluorides, silicates, phosphates, sulfates, and/or heavy metals in the wastewater forming highly insoluble salts that precipitate and settle.
