`
`IN THE CLAIMS
`
`Please amend claims 55 and 56 as follows. Please add new dependent claims 87 and88.
`
`1. (Allowed) A method for treating waste water comprising:
`
`providing a flow-through oxygenator comprising an emitter for electrolytic generation of
`
`microbubbles of oxygen comprising an anode separatedat a critical distance from a cathode and
`
`a powersourceall in electrical communication with each other,
`
`placing the emitter within a conduit; and
`
`passing waste water through the conduit.
`
`Claims 2-54, 60-65, 67-69, 71-73, 75-79, 82-84, 86. (Cancelled).
`
`55. (Currently Amended) A method for producing an oxygenated aqueous composition
`
`comprising:
`
`flowing water at uptoa maximum flowrate of 12 gallons per minute through an
`
`electrolysis emitter comprising an electrical power source electrically connected to an anode
`
`electrode and a cathode electrode contained in a tubular housing,
`
`causing electricity to flow from the power source to the electrodes, and,
`
`producing the composition comprising a suspension comprising oxygen microbubbles
`
`and nanobubbles in the water, the microbubbles and nanobubbles having a bubble diameter of
`
`less than 50 micronsap
`
`surfacetensien-oftheswater, wherein:
`
`the anode electrode is separated at a critical distance from the cathode
`
`such that the critical distance is from 0.005 inchesto 0.140 inches;
`
`the power source is producesa voltageuptoamaximum ofabout 28.3
`
`volts and an amperage up to a maximum amperageof about 13 amps,
`
`the tubular housing has an inlet and an outlet and a tubular flow axis from
`
`the inlet to the outlet;

`
`the water flowsin the inlet, out the outlet, is in fluid connection with the
`
`electrodes, and has a conductivity produced by the presence of dissolved solids
`
`such that the water supports plant or animallife.
`
`56. (Currently Amended) A method according to claim 55 wherein the housing containsat least
`
`one anodeandat least one cathode, the electrodes; are of a grid or solid design andare relatively
`
`positioned in cross section along the radius of the tubular housing with their long axes
`
`substantially parallel to the tubular water flow axis of the housing.
`
`57. (Previously Presented) A method according to claim 55 wherein the housing has a side arm
`
`positioned at an angle relative to the tubular flow axis and the electrodes are located in the side
`
`arm.
`
`58. (Previously Presented) A method according to claim 57 wherein the side arm contains a
`
`multiple number of anode and cathode electrodes and the electrodes are plate shaped.
`
`59. (Previously Presented) A method according to claim 56 wherein a multiple number of anode
`
`and cathodesare present and are of grid or solid design.
`
`66. (Previously Presented) A method according to claim 55 wherein the water has a temperature
`
`no greater than about ambient temperature at the inlet and the water temperature is a factor for
`
`formation of the suspension.
`
`70. (Previously Presented) A method according to claim 55 wherein the microbubbles and
`
`nanobubbles remain in the waterat least in part for a period up to several hours.
`
`74. (Previously Presented) A method according to claim 70 wherein the period for which the
`
`microbubbles and nanobubblesat least in part remain in the water is determined by containing

`
`the water with microbubbles and nanobubblesin a two and one half gallon aquarium reservoir
`
`container.
`
`80. (Previously Presented) A method according to claim 55 wherein the microbubbles and
`
`nanobubbles supersaturate the water.
`
`81. (Previously Presented) A method according to claim 55 wherein the bubble diameter of the
`
`microbubbles and nanobubblesis less than 0.0006 inches.
`
`85. (Previously Presented) A method according to claim 55 wherein the separation of electrodes
`
`is maintained by a nonconductive spacer.
`
`87. (New) A method according to claim 55 wherein the electrode separation distance is about
`
`0.045 to about 0.06 inches.
`
`88. (New) A method according to claim 55 wherein the microbubbles and nanobubbles are
`
`substantially incapable of breaking the surface tension of the water.
