ABSTRACT:
A point of use water purification system including a housing supporting an untreated water container, a removable and disposable filter means and a treated water receiving container all of which are self contained in relation to the housing to enable the housing to be supported from a countertop or other suitable surface at the point of use. The filter means includes multiple compartments with purification media therein with two of the compartments including plate means coated with a photoactivated catalyst, preferrably titanium oxide (TiO.sub.2). An ultraviolet lamp and reflector directs ultraviolet light energy onto the catalyst. Flow control means is provided in the filter means to provide a slow rate of flow thereby providing long time contact between the water being treated and the purification media in the filter means to provide maximum purification efficiency. The water supply container is removable and refillable to provide a batch purification process well adapted for installation at a point of use in both domestic and industrial applications.
