Abstract: An apparatus for increasing the quantity of dissolved oxygen in water. The apparatus includes an inlet for receiving untreated water. A cell housing having an electrolytic cell therein is coupled to the inlet. A resident time housing is connected to the cell housing for receiving water having oxygen and hydrogen gas therein. The resident time housing is vertically oriented and longitudinally extending for a selected vertical length above the cell housing. This provides sufficient resident time of the water in a quiet zone to permit the generated oxygen gas to transition into the dissolved state prior to reaching the top of the resident time housing. An outlet is provided at the top of the resident time housing. Treated water having a high dissolved oxygen content is delivered out of the outlet. A gas vent is provided at the outlet to permit the escape of hydrogen or other gases which have not been dissolved into the water.

Abstract: A method and apparatus for increasing the oxygen content of water have been shown and described. A volume of water is passed between the electrodes of an electrolytic cell, a portion of the volume of water converting to dissolved oxygen. A desired level of dissolved oxygen is selected, and the number of times the volume of water must flow through the electrolytic cell to ensure that the volume of water contains the selected percentage of dissolved oxygen is also selected. The volume of water is then forced through the cell the selected number of times, such that the volume of water contains the desired percentage of dissolved oxygen. The electrolytic cell is in fluid communication with a tank and a pump, the pump drawing the volume of water from the tank and forcing it through the electrolytic cell and back into the tank. The volume of water is thereby recirculated through the electrolytic cell by the pump for the selected number of times.

Abstract: A hand portable water purification system includes a portable electrolytic cell to increase the content of oxygen and chlorine in water to be purified. The electrolytic cell includes a housing and a set of electrodes. The housing provides physical support and spacing for the electrodes and protects the electrolytic cell from damage during handling and storage. The hand portable apparatus has a system control circuit that converts an external source of power to a direct current (DC) voltage to energize the electrolytic cell. The combination of the electrolytic cell and the system control circuit is small enough and light enough to be carried in a person's hand. In one embodiment, the portable electrolytic cell is mounted near the bottom of a container with one-half to five gallon capacity mounted either permanently or detachably.

Abstract: An apparatus for increasing the quantity of dissolved oxygen in water. The apparatus includes an inlet for receiving untreated water. A cell housing having an electrolytic cell therein is coupled to the inlet. A translucent resident time housing is connected to the cell housing for receiving water containing oxygen and hydrogen gas. The resident time housing is vertically oriented and longitudinally extended for a selected vertical length above the cell housing. This provides sufficient resident time of the water in a quiet zone to permit the generated oxygen gas to transition into the dissolved state prior to reaching the top of the resident time housing. An outlet is provided at the top of the resident time housing to dispense water having a high dissolved oxygen content. A gas vent is provided at the outlet to permit the escape of hydrogen or other gases which have not been dissolved into the water. Preferably, a chill unit is provided prior to the electrolytic cell to reduce the temperature of the water.

Abstract: A method and apparatus for generating oxygenated water are shown and described. A plurality of electrolytic cells are coupled to each other and to a source of water. A volume of water is drawn from the source, and forced through at least one of the electrolytic cells at a user desired flow rate. If the demanded rate of flow at the outlet exceeds a threshold flow rate through the electrolytic cell, a valve is opened and an additional volume of water flows through the second electrolytic cell to the discharge, the rate of flow through each electrolytic cell not exceeding the selected value. Additional cells are added as needed. A varying demand of oxygenated water is therefore met, while ensuring that the dissolved oxygen content of the water at the outlet does not fall below a selected value.
