Abstract
Methods and liquid compositions for stabilizing an oxidizing biocide in a water system. The liquid composition comprises a hydantoin, and a surfactant, a ratio of a concentration of the hydantoin to the surfactant in the liquid composition is in a range of 1:1 to 99:1 by volume. The method comprises mixing a hydantoin, a surfactant and an oxidizing biocide with water to form a liquid treatment composition, and then adding the liquid treatment composition to a water stream in the water system, the liquid treatment composition improving the efficacy of the oxidizing biocide in the water stream.
Claims10
A method for stabilizing an oxidizing biocide, the method comprising:
- mixing an unhalogenated hydantoin and a surfactant with water to form a liquid treatment composition;
- and
- then adding a mixture of the liquid treatment composition and an oxidizing biocide to a water stream in a water system, the liquid treatment composition improving the efficacy of the oxidizing biocide in the water stream,
- wherein the oxidizing biocide is selected from the group consisting of calcium hypochlorite, chlorine gas and sodium hypochlorite.
