Abstract
Abstract Water may be purified through the utilization of ultraviolet light and ozone so as to obtain some residual ozone in the water treated by passing a mixture of water and air or air and ozone through a nozzle which concurrently compresses the mixture and breaks up any gas bubbles within the mixture into what may be loosely referred to as a radiation housing or chamber. The housing is a hollow, cylindrical chamber located around an elongated tubular lamp for producing actinic light such as ultraviolet light. The mixture is introduced into this chamber in a substantially tangential manner so as to swirl around the interior chamber in passing from the inlet of the chamber where the nozzle is located to the outlet of the chamber at the other end of the chamber.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
155 words
An apparatus having a centrally located, elongated, tubular lamp for producing actinic radiation and a generally cylindrical housing located concentrically around said lamp, said housing including a centrally located tube capable of transmitting radiation into the interior of said housing located around and immediately adjacent to said lamp, said housing also including an inlet leading into one end of said housing and an outlet leading from the other end of said housing in which the improvement comprises: nozzle means located generally within said inlet for concurrently compressing a gas-liquid mixture conveyed to said nozzle means and said inlet and for breaking up gas bubbles within said mixture so that they are smaller than about 0.5 mm. in diameter, said nozzle means being located so that the gas-liquid mixture being emitted from it swirls in a spiral manner around the interior of said housing as it passes from said inlet to said outlet of said housing.
Claim 2
Independent Claim
155 words
An apparatus having a centrally located, elongated, tubular lamp for producing actinic radiation and a generally cylindrical housing located concentrically around said lamp, said housing including a centrally located tube capable of transmitting radiation into the interior of said housing located around and immediately adjacent to said lamp, said housing also including an inlet leading into one end of said housing and an outlet leading from the other end of said housing in which the improvement comprises: nozzle means located generally within said inlet for concurrently compressing a gas-liquid mixture conveyed to said nozzle means and said inlet and for breaking up gas bubbles within said mixture so that they are smaller than about 0.5 mm. in diameter, said nozzle means being located so that the gas-liquid mixture being emitted from it swirls in a spiral manner around the interior of said housing as it passes from said inlet to said outlet of said housing.
Claim 3
Dependent Claim
48 words
An apparatus as claimed in claim 1 wherein: said nozzle means includes an elongated passage having a constriction intermediate its ends and includes at least one auxiliary passage leading from the exterior of said nozzle means within said housing so as to intersect said constriction within said passage.
Claim 4
Dependent Claim
33 words
An apparatus as claimed in claim 2 wherein: there are a plurality of said auxiliary passages located so as to intersect said constriction equidistant from one another around the exterior of said constriction.
Claim 5
Dependent Claim
53 words
An apparatus as claimed in claim 1 wherein: said nozzle means includes an internal passage having the shape of a venturi tube, said tube including a throat of lesser dimension than the remainder of said passage, and including at least one auxiliary passage leading from the interior of said housing to said throat.
Claim 6
Dependent Claim
24 words
An apparatus as claimed in claim 4 including: a plurality of said auxiliary passages, said auxiliary passages intersecting said throat completely around said throat.
Claim 7
Independent Claim
21 words
An apparatus as claimed in claims 1, 2 or 4 including: pump means for providing a gas-liquid mixture to said inlet.
Claim 8
Independent Claim
64 words
An apparatus as claimed in claims 1, 2 or 4 wherein: said tube is spaced from the exterior of said lamp, and including pump means for providing a liquid-gas mixture to said inlet, means for conveying an ozone-gas mixture from within the space the exterior of said lamp and said tube to said pump means, means for conveying a liquid to said pump means.
Claim 9
Dependent Claim
18 words
An apparatus as claimed in claim 7 further including: means for conveying ambient air to said pump means.
Claim 10
Dependent Claim
141 words
A process for exposing a gas-liquid mixture to actinic light by passing said mixture adjacent to an elongated source of actinic light in which the improvement comprises: compressing said gas-liquid mixture while concurrently breaking up any gas bubbles within said mixture under such conditions that the mixture at the time it is compressed and at the time the bubbles are broken up are subject to turbulence and a shearing type action so as to produce a gas-liquid mixture in which the broken up gas bubbles are less than about 0.5 mm. in diameter, and swirling the so produced gas-liquid mixture in a spiral manner around a source of actinic light in such a manner that the mixture as it is swirling travels along the length of said source of light and under such conditions that there is turbulence within said mixture.
Claim 11
Dependent Claim
141 words
A process for exposing a gas-liquid mixture to actinic light by passing said mixture adjacent to an elongated source of actinic light in which the improvement comprises: compressing said gas-liquid mixture while concurrently breaking up any gas bubbles within said mixture under such conditions that the mixture at the time it is compressed and at the time the bubbles are broken up are subject to turbulence and a shearing type action so as to produce a gas-liquid mixture in which the broken up gas bubbles are less than about 0.5 mm. in diameter, and swirling the so produced gas-liquid mixture in a spiral manner around a source of actinic light in such a manner that the mixture as it is swirling travels along the length of said source of light and under such conditions that there is turbulence within said mixture.
Claim 12
Dependent Claim
39 words
A process as claimed in claim 9 wherein: said gas-liquid mixture is compressed and gas bubbles within said mixture are broken up by passing said mixture under pressure through a passage in a nozzle having a constriction located therein.
Claim 13
Dependent Claim
57 words
A process as claimed in claim 10 wherein: said nozzle includes auxiliary passage means extending from the exterior of said nozzle within said housing to said constriction, and the passage of said gas-liquid mixture through said constriction draws a gas-liquid mixture from within the interior of said housing into said passage in the area of said constriction.
Claim 14
Dependent Claim
27 words
A process as claimed in claims 9 or 11 wherein: said gas-liquid mixture comprises water containing a reactant selected from the group consisting of oxygen and ozone.
