Abstract
Abstract A method of reconditioning a liquid substance that has been contaminated with micro-organisms, in which the substance to be reconditioned is introduced into a container and ozone is conducted through the substance while this is being agitated. The liquid substance may be ozonized in two consecutive stages, the ozone in the first stage being at a gauge pressure, whereas in the following stage it is decompressed substantially to atmospheric pressure. Apparatus for performing the method is also described and claimed.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
125 words
Apparatus for reconditioning a liquid contaminated with microorganisms comprising a container provided with at least one entry and one exit for the liquid to be reconditioned, at least one agitating means which projects into the container and at least one device near the bottom of the container for the introduction of finely divided bubbles of ozone into the container, each such device comprising ozone distributors distributed over substantially the entire cross-section of the container, said distributors being disposed horizontally and substantially in a plane inside the space enclosed by an endless rotating metal mesh in such manner that the liquid to be reconditioned flows through the two meshes and at the same time contacts the finely divided bubbles of ozone issuing from the ozone distributor.
Claim 2
Dependent Claim
125 words
Apparatus for reconditioning a liquid contaminated with microorganisms comprising a container provided with at least one entry and one exit for the liquid to be reconditioned, at least one agitating means which projects into the container and at least one device near the bottom of the container for the introduction of finely divided bubbles of ozone into the container, each such device comprising ozone distributors distributed over substantially the entire cross-section of the container, said distributors being disposed horizontally and substantially in a plane inside the space enclosed by an endless rotating metal mesh in such manner that the liquid to be reconditioned flows through the two meshes and at the same time contacts the finely divided bubbles of ozone issuing from the ozone distributor.
Claim 3
Dependent Claim
27 words
Apparatus according to claim 1, comprising at least one pressure ozonizer inside the container, which pressure ozonizer precedes the said devices and forms a first ozonization stage.
Claim 4
Dependent Claim
67 words
Apparatus according to claim 2, in which the pressure ozonizer comprises a cylindrical shell with an open bottom, into which a liquid inlet pipe provided with lateral outlet openings projects, the end of said inlet pipe being closed and the interior of the inlet pipe containing a plurality of vertically aligned ozone distributors supplied with ozone through a pipe that is coaxial with the liquid inlet pipe.
Claim 5
Dependent Claim
48 words
Apparatus according to claim 3, in which the liquid inlet pipe extends to the bottom edge of the cylindrical shell and the annular cross-section that remains for the discharge therethrough of the ozonized substance is variable for the purpose of controlling the pressure existing inside the pressure ozonizer
Claim 6
Dependent Claim
37 words
Apparatus according to claim 1, in which the said ozone distributors have the form of ceramic tubes from which the ozone that is axially introduced into one end thereof issues in the form of finely divided bubbles.
