Abstract

A process for deionizing water, containing mineral ions, in relatively larger amounts and silica in relatively smaller amounts, comprising treating the water to produce an acidic softened water, then contacting the acidic water with a weakly basic anion exchanger and then bringing in the water in contact with a strongly basic Type I anion exchanger, characterized in that the water that has been brought into contact with the cation exchanger is divided into a larger part and a smaller part, said larger part is brought into contact with the weakly basic exchanger and the major part thus treated mixes with said minor part to form water containing silica ions and mineral acid, the ratio of silica ions/mineral acid ions being within the range of 6/4 to 9, 8/0.2, which water is then brought into contact with the anion exchanger strongly basic.
