Abstract (en)
[origin: WO02083570A1] An apparatus and method for the photocatalytic purification and ultrapurification of water. Water containing organic, inorganic, and/or biological contaminants is directed through a rigid, three-dimensionally open celled, fluid permeable, semiconductor unit (18). Within the unit, a semiconductor surface capable of promoting electrons from its valence band to its conduction band, when exposed to a photoactivating light source (38, 40), removes the contaminants through a photocatalytic reaction.
