Abstract
Embodiments of a method of producing an aqueous powder composition for treating water comprise mixing sodium metabisulfite powder with amines, wherein the amines comprises liquid cyclohexylamine, and adding water to the mixture of sodium metabisulfite powder and liquid cyclohexylamine to catalyze the production of the aqueous powder composition.
Claims6
A method of producing a dry powder composition for treating water comprising:
- mixing sodium metabisulfite powder with amines, wherein the amines comprise liquid cyclohexylamine;
- and
- adding water to the mixture of sodium metabisulfite powder and liquid cyclohexylamine to catalyze production of the dry powder composition,
- wherein the dry powder composition consists of about 35 to about 55% by weight of amines, wherein the amines comprise liquid cyclohexylamine and optionally one or more additional amines, about 35 to about 55% by weight of bisulfites selected from the group consisting of sodium bisulfite, sodium metabisulfite, and mixtures thereof, and about 5 to about 10% by weight of water.
