Abstract
Abstract A floating liquid aerator and water treatment device adapted for use in aerating and chemical treatment of polluted water. The device includes an axial flow impeller rotated by motor means disposed above a centrally located tube. The motor and impeller, pump water upwardly through the tube and sling it outwardly for interface contact with the particular surrounding atmosphere. The impeller slings the water into the atmosphere with considerable turbulence thereby exposing more of the water surface to the atmosphere, resulting in a higher transfer of oxygen or other gas to the water. The base of the floating aerator includes an extended tube which communicates between the interior of the floating liquid aerator and a point beneath the float near or just above the floor of the body of water. As the aerated or treated water head builds up within the float, the aerated or treated water is forced down the tube thereby causing a gentle flow of aerated or treated water outward and upward near the bottom of the body of water. In addition, means are provided to chemically treat the aerated water whereby the chemicals will be thoroughly dispersed and diluted before being exposed to the environment.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
110 words
In a liquid aerator and water treatment device, the combination of a support capable of floating, said support having treated water retaining means whereby said treated water is prevented from mixing with the ambient water, communicating means fixedly attached to the base of said support whereby said treated water is introduced into said ambient water at a remote location from said support, intake and spraying means operatively attached to said treated water retaining means whereby ambient water is brought into said support and sprayed through the air into said treated water retaining means thereby obtaining intimate surface contact, aeration and treatment between the particles of water and air or chemicals.
Claim 2
Dependent Claim
110 words
In a liquid aerator and water treatment device, the combination of a support capable of floating, said support having treated water retaining means whereby said treated water is prevented from mixing with the ambient water, communicating means fixedly attached to the base of said support whereby said treated water is introduced into said ambient water at a remote location from said support, intake and spraying means operatively attached to said treated water retaining means whereby ambient water is brought into said support and sprayed through the air into said treated water retaining means thereby obtaining intimate surface contact, aeration and treatment between the particles of water and air or chemicals.
Claim 3
Dependent Claim
58 words
A liquid aerator and water treatment device as defined by claim 1 in which said treated water retaining means comprises a flat base portion having an aperture arranged to receive said communicating means, the periphery of said base having an upwardly extending side wall whereby said base, side wall and communicating means thereby define saId treated water retainer.
Claim 4
Dependent Claim
31 words
A liquid aerator and water treatment device as defined by claim 2 in which said side wall, said base and said communicating means are conjoined in a substantially liquid tight relationship.
Claim 5
Dependent Claim
34 words
A liquid aerator and water treatment device as defined by claim 3 wherein said base is substantially circular and wherein said side wall is upwardly extending and conjoined to the periphery of said base.
Claim 6
Dependent Claim
48 words
A liquid aerator and water treatment device as defined by claim 1 wherein said communicating means comprise a tube attached to said base in a sealing relationship and extending downwardly from said base and arranged so as to transport said aerated or treated water to said remote location.
Claim 7
Dependent Claim
32 words
A liquid aerator and water treatment device as defined by claim 2 wherein said flat base portion is provided with additional float means arranged so as to insure said support remains floating.
Claim 8
Dependent Claim
54 words
A liquid aerator and water treatment device as defined by claim 1 wherein said intake and spraying means comprise an intake tube operatively connected with motor means arranged to rotate spray means whereby ambient water is drawn from outside said support and sprayed in a substantially horizontal plane symmetrically about said rotating spray means.
Claim 9
Dependent Claim
29 words
A liquid aerator and water treatment device as defined by claim 7 having screening means affixed to said base whereby particulate matter is prevented from entering said intake tube.
Claim 10
Dependent Claim
29 words
A liquid aerator and water treatment device of claim 4 wherein cover means are provided whereby said water is prevented from being sprayed outside said treated water retaining means.
Claim 11
Dependent Claim
28 words
A liquid aerator and water treatment device of claim 1 having means to introduce substances such as solids, liquids, foams or gases into said treated water retaining means.
Claim 12
Dependent Claim
29 words
A liquid aerator and water treatment device as defined by claim 4 wherein the interior of said side wall is irregular thereby causing severe turbulence of said impinging water.
Claim 13
Dependent Claim
18 words
A liquid aerator and water treatment device as defined by claim 4 whereby said irregularities are rounded corrugations.
Claim 14
Dependent Claim
31 words
A liquid aerator and water treatment device as defined by claim 4 wherein screen mesh means are fixedly held in at a spaced relation between said impeller and said side wall.
Claim 15
Dependent Claim
33 words
A liquid aerator and water treatment device as defined by claim 9 wherein chemical introduction means are provided whereby chemicals are introduced directly into said intake tube wherein said chemicals are sprayed outwardly.
