摘要
A process for the partial desalination of water with a combination of weakly acid cation exchangers in free acid form and basic anion exchangers in hydrogen carbonate form, both present in aqueous suspensions, and subsequent regeneration of the charged ion exchanger material. The partial desalination is effected with a combination or mixture of a weakly acid cation exchanger material and a basic anion exchanger material. Depending on the combination or mixing ratio of the two exchangers, non-equivalent quantities of neutral salt cations and anions are removed from the water. The regeneration of both exchangers together is effected exclusively with the aid of CO2.
