ABSTRACT:
The point-of-use water treatment system for treating water to be dispensed from a container includes a filter media positioned adjacent a water input opening of the container, through which water is filtered into the container. The filter media includes a water soluble disinfectant positioned thereon or therein, with the preferred disinfectant tetraglycine hydroperiodide, chloramine-T, or calcium hypochlorite. The disinfectant dissolves in the water as it passes through the filter, and reduces the biological activity of microbiological agents in the water. A point-of-use method of the present invention which reduces microbiological contamination in a predetermined volume of water to be dispensed from a container which utilizes a filter media containing a water soluble disinfectant impregnated thereon is also disclosed. The method includes the steps of positioning the filter media adjacent the opening of the container, filtering water through the filter media, dissolving the disinfectant in the water as it passes through the filter media, allowing the disinfectant to contact and deactivate microbiological agents in the water, and disposing of the filter media.
