Lime-Soda Ash Softening MRWA
Lime Softening 1 Lime Softening . Chemical precipitation is one of the more common methods used to soften water. Chemicals normally used are lime (calcium hydroxide, Ca(OH) 2) and soda ash (sodium carbonate, Na 2CO 3). Lime is used to remove chemicals that cause carbonate hardness. Soda ash is used to remove chemicals that cause non-carbonate

Lime softening Wikipedia
Lime softening, also known as Clark's process, is a type of water treatment used for water softening which uses the addition of limewater (calcium hydroxide) to remove hardness (calcium and magnesium) ions by precipitation.The process is also effective at removing a variety of microorganisms and dissolved organic matter by flocculation.

Recarbonation and Softening SpringerLink
Abstract. According to Wang (), recarbonation is defined as “(a) the process of introducing carbon dioxide, CO 2, as a final stage in the lime-soda ash softening process in order to convert carbonates to bicarbonates and thereby stabilize the solution against precipitation of carbonates, (b) the diffusion of carbon dioxide gas through liquid to replace the carbon dioxide gas removed by the
