An apparatus and method for the photocatalytic purification and ultrapurification of water. Water containing organic, inorganic and/or biological contaminants is directed through an open cell, three dimensionally reticulated, fluid permeable, semiconductor unit. 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, removes the contaminants through a photocatalytic reaction.
