Water Treatment
Anhydrous calcium chloride is used in waste water treatment applications to remove undesired impurities. The petroleum, metal working, laundry, textile and food processing industries add calcium chloride to oily waste streams to cause oil droplets to float to the surface where they can be removed by skimming. When calcium chloride is added to water containing fluorides, silicates, phosphates, sulfates, and heavy metals, it reacts with the contaminants to form highly insoluble salts, which precipitate, settle and can then be removed from the bottom of the stream.
