Abstract

Water softening compositions, and related systems and methods are disclosed. The present disclosure involves a composition for the regeneration of cation exchange media. The regenerant composition includes an alkali metal formate salt (and optionally a metal halide salt). The present disclosure also involves a systems and methods for treating a cation exchange medium in a water softener to replace hardness cations therefrom with alkali metal cations (such as Naand K. The method includes contacting the media with a regenerant including an alkali metal formate salt (and optionally an alkali metal halide salt). The method also includes contacting the media with the regenerant in an amount sufficient to regenerant the ion exchange medium. According to the method, the hardness cations coupled to the cation exchange media are replaced with the alkali metal cations.
