Photocatalytic filter unit, for removing organic components from air or liquid, includes filter medium containing activated carbon and titanium dioxide and UV source for photolysis

摘要

In a photocatalytic filter unit for treating air or liquid (7), comprising a head (1) fixed on a bowl (2) carrying a grating element (3) containing a medium (4) consisting of an absorbent layer of activated carbon and a surface deposit of titanium dioxide (TiO 2), the medium converts organic materials under the action of a source (5) of UV-A or UV-C radiation and an opening system (13) in the base of the medium eliminates loss of charge.
