Abstract
Novel water softening compositions and methods of treating hard water are provided. The compositions comprise a blend of sodium chloride and potassium chloride. The compositions are useful for regenerating ion exchange material in a water softening system and providing softened water containing both sodium and potassium ions.
Claims21
A method of treating water, comprising contacting an ion exchange material with an aqueous solution comprising a blend of sodium chloride and potassium chloride to yield a regenerated ion exchange material.
A water softening blend comprising sodium chloride and potassium chloride, said blend being in the form of pieces having a maximum surface-to-surface dimension of less than about 4 inches and a minimum surface-to-surface dimension of at least about 0.25 inches.
A water softening composition comprising sodium chloride, potassium chloride, and an additive selected from the group consisting of binders, chelating agents, and mixtures thereof.
