Abstract
Abstract Device for treating a liquid and in particular drinking water or waste waters. The device comprises a tube which is immersed in the liquid in a tank and communicates at its upper end with treating gas-supply means. A diffuser having radial vanes fixed to a rotating disc communicates with the lower end of the tube. A pump disposed under and coaxial with the diffuser pumps the liquid from the tank through passages in the disc into chambers defined by the vanes so as to form in the chambers an emulsion of the gas and liquid which is thereafter ejected into the liquid in the tank.

Claim 1
Independent Claim
274 words
A device for treating a liquid and in particular for treating drinking water or waste waters, comprising in combination an upwardly extending tube for immersion in the liquid, means for supplying directly to the interior of the tube a treating gas under pressure, a centrifugal distributor for diffusing the gas in the liquid and combined coaxially with a lower part of the tube for immersion in the liquid, the distributor comprising upper radially extending wall means, lower radially extending wall means axially spaced from the upper wall means, a plurality of vanes extending outwardly of the distributor axis and defining with the upper wall means and lower wall means radially outwardly divergent chambers having radially inner ends and radially outer ends, the outer ends being open, treating gas inlet means connecting the interior of the tube to the inner ends of the chambers, means defining throughway orifices in the lower wall means in positions adjacent the inner ends of the chambers for putting the inner ends of the chambers in communication with a side of the lower wall means remote from the vanes, pump means having inlet means for the liquid and delivery outlet means for the liquid, which outlet means are axially adjacent said side of the lower wall means remote from the vanes and communicate with the orifices for pumping the liquid through the orifices into the chambers and producing in the chambers an emulsion of the liquid to be treated and the treating gas, and drive means for actuating the pump and driving the vanes in rotation so as to drive the emulsion outwardly through the open ends of the chambers.
Claim 2

Claim 3
Dependent Claim
31 words
A device as claimed in claim 1, wherein the flow of liquid delivered by the pump represents a given percentage of the flow of treating gas supplied by the supply means.
Claim 4
Dependent Claim
14 words

Claim 5
Independent Claim
403 words
A device for treating a liquid and in particular for treating drinking water or waste waters, comprising in combination an upwardly extending tube for immersion in the liquid, means for supplying directly to the interior of the tube a treating gas under pressure, a centrifugal distributor for diffusing the gas in the liquid, the distributor comprising a fixed upper side wall and a fixed lower side wall spaced from the upper side wall, means defining an aperture in each of the side walls, the upper side wall being fixed along a portion of the upper side wall adjacent the periphery of its aperture to a lower open end portion of the tube, drive means having an output shaft extending axially through the apertures of the upper side wall and lower side wall, a disc located between and in spaced relation to the upper side wall and lower side wall, means drivingly connecting the shaft to the disc, a plurality of first vanes in fixed relation to a first face of the disc and extending outwardly of the shaft and defining with the upper wall and first face of the disc radially outwardly divergent chambers which have radially inner ends adjacent the aperture of the upper side wall and radially outer ends adjacent an outer peripheral edge of the upper wall and an outer peripheral edge of the disc, the chambers being open at the outer ends of the chambers, means defining throughway orifices in the disc in positions adjacent the periphery of the aperture of the upper side wall for putting the inner ends of the chambers in communication with a second face of the disc opposed to the first face of the disc, a pump comprising a body having an annular portiOn which is secured to the lower side wall adjacent the aperture of the lower side wall and defines liquid inlet means adjacent the shaft, and liquid outlet means adjacent the lower wall aperture, a plurality of second vanes adjacent said second face of the disc and extending outwardly of the shaft, the second vanes having radially inner ends adjacent the inlet means and radially outer ends adjacent the outlet means and adjacent the orifices, and means drivingly connecting the shaft to the second vanes whereby liquid drawn in by way of the inlet means is pumped by the second vanes through the orifices to the inner ends of the chambers.
