Abstract
In a process for the partial desalination of water, especially of drinking water, with a mixture of weakly acid cation exchangers and strongly basic anion exchangers, whereby the charged ion exchangers are regenerated by CO.sub.2 -containing water, if required, with the addition of CaCO.sub.3, CaCO.sub.3 /MgO, Ca(OH).sub.2 or the like. Simultaneous with the partial desalination, the organic carbon compounds present in the water are reduced, whereby the charged ion exchangers are intermittently regenerated with HCl, NaCl, NaOH, or a mixture of NaCl and NaOH.
