Abstract
A water system for supplying chilled water to a food production line. The chilled water is held in a holding tank which is sampled by a pump which delivers water to an analyzer. The water is first filtered to remove debris that would hamper the analysis. The analyzer determines the disinfectant level in the water, and generates a signal indicative of that level. When the disinfectant level falls below a predetermined level, a disinfection pump is activated to deliver additional disinfectant to the tank. The preferred disinfectant is Liquid Chlorine(sodium hypochlorite). The analyzer can measure the free available chlorine level, pH or oxidation-reduction potential of the water.
