Lime softening (also known as lime buttering, lime-soda treatment, or Clark's process)[1] is a type of water treatment used for water softening, which uses the addition of limewater (calcium hydroxide) to remove hardness (deposits of calcium and magnesium salts) by precipitation. The process is also effective at removing a variety of microorganisms and dissolved organic matter by flocculation.[2]
