Abstract
Abstract An apparatus for treatment of waste water in a body such as a lagoon in which a submerged aeration device is suspended from a floating platform. Air is supplied to the aeration device by a conduit passing through the buoyant base of the platform to a central opening so that the conduit is an integral, structural part of the platform.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
253 words
An apparatus for treatment of waste water in a body of waste water comprising: means for mixing a gas with said waste water including a water manifold, a gas manifold, a plurality of nozzles extending outward from said water manifold and connected to said gas and water manifolds with water passing through each nozzle from inlet to outlet and gas being mixed with water in said nozzle, means including a pump for pumping said waste water into said water manifold, means for supplying said gas to said gas manifold; a floating platform including a base closed on all sides and providing bouyancy for floating in a horizontal plane, said base having a central opening between the atmosphere and the surface of said body and exposing said surface to the atmosphere, the distance between the outlets of the most separated nozzles being about no less than the least dimension of the base in said horizontal plane; means mounted on said platform and extending through said opening for suspending said mixing means from said platform, the cross-sectional area of said opening being sufficient to withdraw said pump therethrough to a position above said platform and being at least as great as the intake area of said pump; and means for supplying said gas to said mixing means and forming a structural part of said platform, said supplying means comprising a conduit extending into said opening and horizontally through said base between said central opening and a peripheral surface to increase the stability of said platform.
Claim 2
Independent Claim
253 words
An apparatus for treatment of waste water in a body of waste water comprising: means for mixing a gas with said waste water including a water manifold, a gas manifold, a plurality of nozzles extending outward from said water manifold and connected to said gas and water manifolds with water passing through each nozzle from inlet to outlet and gas being mixed with water in said nozzle, means including a pump for pumping said waste water into said water manifold, means for supplying said gas to said gas manifold; a floating platform including a base closed on all sides and providing bouyancy for floating in a horizontal plane, said base having a central opening between the atmosphere and the surface of said body and exposing said surface to the atmosphere, the distance between the outlets of the most separated nozzles being about no less than the least dimension of the base in said horizontal plane; means mounted on said platform and extending through said opening for suspending said mixing means from said platform, the cross-sectional area of said opening being sufficient to withdraw said pump therethrough to a position above said platform and being at least as great as the intake area of said pump; and means for supplying said gas to said mixing means and forming a structural part of said platform, said supplying means comprising a conduit extending into said opening and horizontally through said base between said central opening and a peripheral surface to increase the stability of said platform.
