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.
L'invention concerne un appareil et un procédé de purification et d'ultrapurification photocatalytique d'eau. L'eau contenant des contaminants organiques, inorganiques, et/ou biologiques dirigés à travers un module à semi-conducteur (18) rigide, à alvéole à ouverture tridimensionnelle, perméable au fluide. Dans ce module, une surface à semi-conducteur capable d'activer les électrons d'une bande de valence vers une bande de conduction, lorsqu'ils sont exposés à une source de lumière photo-activante (38, 40), élimine les contaminants à l'aide d'une réaction photocatalytique.
