Abstract
A cartridge for a water treatment system, effective to assist in the removal of contaminants by photocatalytic oxidation and by adsorption, includes a plurality of stacked disks, preferably made of a UV light transmissive material, which disks define circuitous flow paths for water being treated. In a preferred embodiment, the disk surfaces contacted by the water are provided with a coating of a catalyst, such as TiO, activated by a UV light source positioned in the center of the cartridge.
