ION EXCHANGE METHODS FOR TREATING WATER HARDNESS |
摘要 |
The present invention includes a novel salt-free water softening method that utilizes an exchange medium (such as a gel exchange polymer, a macroporous exchange polymer, or an inorganic cation exchanger) that is pre-loaded with a polyvalent cation that has low solubility in aqueous phase at nearly neutral pH. The method of the invention does not require use of a sodium salt or mineral acid in the regeneration of the exchange medium. |
