2 Foreign Trade Imports of crude and anhydrous sodium sulfate decreased 14% in 1994, primarily from Canada and Mexico. The average c.i.f. value remained virtually the same--$82.63 per ton in

Precipitation Softening Processes | GE Water

Precipitation softening processes are used to reduce raw water hardness, alkalinity, silica, and other constituents. This helps prepare water for direct use as cooling tower makeup or as a first-stage treatment followed by ion exchange for boiler makeup or process use.

sodium sulfates - an overview | ScienceDirect Topics

Because sodium and magnesium sulfate exert a cathartic action, the recommended sulfate concentration in potable supplies is limited to 250 mg/L. Sulfate ion is precipitated in a hydrochloric acid medium with barium chloride in such manner as to form barium sulfate crystals of uniform size.
