zeolite process for water softening | Hard and Soft Water

Jan 29, 2014 · The zeolites are hydrated aluminosilicates and general composition Al x Si y O 2(x+y) The softening water by this process is used for laundry process and cannot be used for boiler purpose. Because this water softening system contains NaHCO 3 in the water; when this water is heated, it produces CO 2 which is corrosive for boilerplates.

Water Handbook - Boiler System Failures | SUEZ

The boiler water often contains elements that become corrosive when concentrated far beyond normal values as a result of design problems. Many industrial boilers, for example, are treated in such a manner that low concentrations of caustic soda are present in the boiler water. The caustic can become corrosive to steel when the boiler water is
