WaterSolutions Separation of Alkali Metals from Liquid Media

Water/Wastewater: Removal of alkali metals from water and organic solvents via ion exchange is common in chemical, petrochemical, oil refining, semiconductor manufacturing, and power utility plants. In waters with low levels of dissolved salts, strongly acidic cation exchange resins such as DOWEX™ G-26 (H) cation exchange resin are employed. Under alkaline conditions, a weak acid cation exchange resin such as DOWEX MAC-3 will provide higher capacity and easier regeneration.

Alkali metals can also be removed from water with reverse osmosis membranes.
