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.

Compositions and methods for treating water by stabilizing an oxidizing biocide

A method for inhibiting corrosion of a corrodible metal surface that contacts water in a water system is provided. The method may include introducing into the water a treatment composition including an ex-situ halogenated triazole compound in an amount sufficient for inhibiting corrosion. A method of measuring a concentration of the ex-situ halogenated triazole compound in water in a water system is also provided. The method may include inducing the halogenated triazole compound to fluoresce and measuring an intensity of the fluorescence emitted from the water to determine the concentration of the halogenated triazole compound in the water. The concentration of the halogenated triazole can be monitored and controlled. The concentration of the halogenated triazole can be adjusted to a desired level based on the measured fluorescence value.
