ABSTRACT:
An integrated filtration and sterilization apparatus including an ultraviolet lamp disposed within an ultraviolet radiation permeable sleeve such that a gas conduit is formed between an outer surface of the ultraviolet lamp and an inner surface of the sleeve; a filtration member disposed about the sleeve such that a permeate chamber is formed between an outer surface of the sleeve and an inner surface of the filtration member; a feed chamber disposed about an outer surface of the filtration member; a liquid feed for feeding a liquid to the feed chamber and a liquid removal line for removing liquid from the permeate chamber; a gas feed for feeding an oxygen-containing gas to the gas conduit and a gas removal line for removing an ozone-containing gas from the gas conduit; and a mixing device for mixing liquid removed from the permeate chamber and ozone-containing gas from the gas conduit downstream from the permeate chamber.
