This study examines the water purification by cylindrical wetted-wall reactor using corona discharge in gas phase. In this reactor, a cylindrical anode and a wire cathode are set apart from each other coaxially in an atmospheric air to generate corona discharge. The cylindrical anode surface is covered with falling water film by overflowing treated water from its top, and the outlet water is circulated to the reactor. Some reactive species, O<SUP>-</SUP>, O<SUB>2</SUB><SUP>-</SUP>, O<SUB>3</SUB>, O are produced by gaseous corona discharge, and the ions should arrive at the treated water flowing on the anode surface by electric force, and the uncharged radicals should arrive there by convection caused by ion wind. When these gaseous species reach the water film, they readily react with water to produce aqueous radicals, which contribute to decompose organic contaminants in the treated water. Phenol was chosen as target organic compound. Experiments were carried out in variety of conditions.
