Abstract

1321058 Ion exchange ROHM & HAAS CO 9 July 1970 [9 July 1969] 33416/70 Heading B1J Water is softened in bed 1 by a strong cation exchange and after passing through deaerator 4 the major portion is passed through a weakly basic exchange 8 and is added to a minor portion of the deaerated softened water to be treated in bed 10 which is strongly basic. The ratio of portions is chosen to give a mixed water stream ratio of Si/mineral acid of 6/4 to 9.8/0.2. (For Figure see next page)
