ABSTRACT:
Water may be treated so as to kill microorganisms and so as to oxidize oxidizable material within it by passing a thin film of water in contact with a gaseous body or bubble of air containing both oxygen and ozone while concurrently radiating both the water film and the gas bubble with ultraviolet radiation capable of causing the formation of ozone and killing microorganisms. The water which has been in contact with the gas bubble is collected into a body of water which is thereafter radiated with the same ultraviolet radiation while the water within the body is moved turbulently. This treatment can conveniently be carried out utilizing two containers transparent to the radiation used which are connected at their bottoms. Such containers are preferably located immediately adjacent to an ultraviolet lamp used as the source of the radiation.
