Abstract
Abstract An apparatus for dissolving oxygen in a body of water includes a housing submerged in a body of water. A chamber in the housing maintains a volume of oxygen in surface contact with the water. Oyxgen is supplied to the chamber at a rate not greater than the rate at which oxygen is absorbed by the water to prevent disturbance of the thermocline region in the body of water.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
190 words
A method for dissolving oxygen in the thermocline region of a stratified body of water comprising the steps of: immersing receptacle means in said body of water at a depth below the thermocline, said receptacle means comprising a top wall and a side wall extending downwardly from the periphery of said top wall, introducing a flow of oxygen into said receptacle means to establish a volume of oxygen in a region bounded by said top wall, said side wall, and the surface of said body of water underlying said volume of oxygen, and thereby maintaining a quiescent water-oxygen interface, exhausting oxygen from said receptacle means by absorption into said body of water through the surface contact of the water with the oxygen, and replenishing said volume of oxygen in said receptacle means by supplying oxygen directely to said volume of oxygen at a rate not greater than the rate oxygen is absorbed by said body of water from said volume of oxygen in said receptacle means so that gases are not allowed to escape and flow in an upward direction to disturb the thermocline and destratify the body of water.
Claim 2
Independent Claim
190 words
A method for dissolving oxygen in the thermocline region of a stratified body of water comprising the steps of: immersing receptacle means in said body of water at a depth below the thermocline, said receptacle means comprising a top wall and a side wall extending downwardly from the periphery of said top wall, introducing a flow of oxygen into said receptacle means to establish a volume of oxygen in a region bounded by said top wall, said side wall, and the surface of said body of water underlying said volume of oxygen, and thereby maintaining a quiescent water-oxygen interface, exhausting oxygen from said receptacle means by absorption into said body of water through the surface contact of the water with the oxygen, and replenishing said volume of oxygen in said receptacle means by supplying oxygen directely to said volume of oxygen at a rate not greater than the rate oxygen is absorbed by said body of water from said volume of oxygen in said receptacle means so that gases are not allowed to escape and flow in an upward direction to disturb the thermocline and destratify the body of water.
Claim 3
Dependent Claim
32 words
The method of claim 1 for dissolving oxygen in a thermocline region of a stratified body of water further including the step of introducing a flow of water through said receptacle means.
Claim 4
Dependent Claim
51 words
The method of claim 1 for dissolving oxygen in the thermocline region of a stratified body of water, including the step of maintaining said volume of oxygen at a pressure of one-half pound per foot of depth that said receptacle means is located below the surface of said body of water.
