Abstract
Methods for treating a water system include providing a liquid treatment composition to water within the water system, the liquid treatment composition includes a stabilizer compound, a surfactant and a chlorine containing biocide, and the liquid treatment composition is substantially free of any bromine containing biocide. At one or more points during the treatment, the water of the water system may have a pH of 7.5 or greater. The stabilizer compound may be fed as a separate component into the water of the water system. The water system may be within a pasteurizer or retort cooker.
Claims20
A method for treating a water system, the method comprising:
- providing a liquid treatment composition to water within the water system,
- wherein at one or more points during the treatment, the water of the water system has a pH of 7.5 or greater,
- wherein the liquid treatment composition comprises a stabilizer compound, a surfactant and a chlorine containing biocide, and
- wherein the liquid treatment composition is substantially free of any bromine containing biocide.
A method for treating a water system of a pasteurizer or retort cooker, wherein the water system treats products fed through the pasteurizer or retort cooker, the method comprising:
- providing a liquid treatment composition to water within the water system,
- wherein the liquid treatment composition comprises a stabilizer compound, a surfactant and a chlorine containing biocide, and
- wherein the liquid treatment composition is substantially free of any bromine containing biocide.
A method for treating a water system for biofouling, the method comprising:
- providing a stabilizer compound for a chlorine species to water within the water system, wherein the providing is selected from the group consisting of:
- (a) where the water of the water system contains a chlorine species, providing the stabilizer compound to the water of the water system in a feed composition consisting of the stabilizer compound, optionally water and optionally a surfactant;
- (b) providing the stabilizer compound to the water of the water system in a feed composition consisting of the stabilizer compound, a chlorine containing biocide and optionally water, and separately providing a surfactant to the water of the water system;
- and
- (c) providing the stabilizer compound to the water of the water system in a feed composition consisting of the stabilizer compound, a surfactant and optionally water, and separately providing a chlorine containing biocide to the water of the water system.
