ABSTRACT:
An apparatus for removal of organic materials from water includes a reactor for photocatalytic oxidation and/or ionization of organics in the water stream and an ion exchange column for removal of CO.sub.2, dissolved acids, and ionized organics formed in the reactor from the water stream. The reactor includes an elongated flow chamber having an inlet at one end and an outlet at the opposite end. A photocatalytic material is provided as a surface layer on a number of solid members in the chamber, typically a number of rods extending generally parallel to the axis of the flow chamber. The catalyst may be TiO.sub.2 formed by oxidizing the surface of Ti rods. An elongated UV lamp fitting within a tubular quartz window extends along the axis of the reaction chamber. An external circuit connects the electrodes and the water, such that a current flows in the water in the reaction chamber. A potential of up to 600 VDC may be applied between the solid electrodes and water in the chamber.
