Weak Acid Cation Gel
 
Gel Type Polyacrylic Weak Acid Cation exchanger (WAC). The functional carboxylic groups give high chemical efficiency in many applications, especially for the removal of bicarbonate alkalinity in water treatment and for treating aqueous organic solutions, showing good rates of exchange. The major use  of WAC is in the dealkalization and softening of waters and thereby the ionic load on the subsequent strong acid resin bed can be reduced. Because WAC's have a  lower density than the conventional strong acid resins, WAC are ideal for use in layered beds (Doublite) which can be economically regenerated by an upflow countercurrent technique.  The resin is insoluble in acids, alkalies, and all common solvents. Its physical characteristics are outstanding, and often permit its use where a macroporous resin might otherwise be indicated. Hence Purolite WAC's may be operated successfully at relatively high temperatures, e.g. in sugar treatment.

Weak Acid Cation resins are increasingly being used in special applications including treatment of waste water streams in order to reduce environmental pollution
