  • Water SoftenerWater Treatment Process Plant Design

    Lime Processing Water Softener Lime softening water treatment process involves a relatively complicated series of chemical reactions. The goal of all of these reactions is to change the calcium and magnesium compounds in water into calcium carbonate and magnesium hydroxide which are the least soluble compounds and thus will settle out of the water at the lowest concentrations.

     · However since the chemical cost of quicklime is less than the cost of hydrated lime quicklime is often used in large plants. The slaking process can also allow a large plant to reuse a large quantity of the lime sludge produced in the softening process. First the sludge is heated and the calcium carbonate in the sludge produces calcium oxide.
