Read Morelime 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.
Read Morelime 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.
