ION EXCHANGE RESIN MIXTURES AND THEIR USE IN CATION EXCHANGE PROCESSES Abstract of the Disclosure A mixed cation/anion exchange resin bed is disclosed containing from 0.5 to 20% by volume of acrylic and/or styrenic anion exchange resin. There is also disclosed a process for treating a liquid to remove cations, e.g. hardness ions, therefrom, comprising passing the liquid through the mixed ion exchange resin bed, the anion exchange resin enabling the level of organic material leaching from the cation exchange resin into the liquid to be maintained at an acceptable level, e.g. a level of leached organic material, expressed as total organic carbon and measured by the procedure of DIN Standard 54411, of not more than 3 mg/litre of liquid. The mixed ion exchange resin bed and process of the invention are particularly suitable for the treatment of water to produce softened, potable water, and in sugar processing.
