ABSTRACT:
A water filter is packaged in a way that permits longer dwell time and greater volume in a dwell passage of the water filter. In one embodiment the water filter includes an influent passage where a biocide is imparted to the water, a dwell passage where the water remains in contact with the biocide for at least a predetermined duration, and an effluent passage where the biocide is removed from the water. The water filter includes a replaceable cartridge mounted in a pressure vessel. By arranging the dwell passage to include a pan-shaped portion in the bottom of the vessel and an axial portion along the extremity of the cartridge, greater volume, greater mixing, and more effective disinfecting result. Another embodiment includes a series of baffles on the exterior surface of the cartridge that create further turbulence for mixing the biocide with the water.
