Benefits of technology

It is a further object of the present invention to provide a mixed oxidant generating system with increased ratios of ozone to chorine based compounds.

Problems solved by technology

While large metropolitan water systems can make use of highly toxic chlorine gas for sterilizing drinking water, such systems are impractical in remote locations which lack highly trained personnel and the equipment to maintain the systems.
While this system represents a major improvement over the prior systems, it is less than optimal.

Embodiment Construction

The manner in which an electrolytic cell 10 according to the present invention operates can be more easily understood with references to FIGS. 1-3. Electrolytic cell 10 includes an anode 12 and a cathode 14 which are separated by an insulating gasket 16 thereby forming a flow chamber 24 through which a salt solution is passed. The salt solution is introduced through an input port 18 and exits through an anode port 20 and a cathode port 22. A DC voltage is maintained between anode 12 and cathode 14 with the aid of a power source 24. Anode 12 and cathode 14 are preferably constructed from titanium. In addition, anode 12 preferably includes a Group VIII metal for the reasons discussed below.

Referring to FIG. 3, the flow of salt solution is divided by an extension of gasket 25 into anode and cathode output streams which exit through anode port 20 and cathode port 22, respectively. The flow in chamber 24 is laminar in nature. As the salt solution traverse the chamber 24, the pH of the so...

Abstract

An electrolytic cell for generating a mixed oxidant that is rich in ozone is disclosed. The cell disassociates a brine solution to generate ozone and chlorine based oxidants. The improved cell design allows the ratio of ozone to the other oxidants to be optimized, thereby providing a more efficient sterilization solution. The ozone production is adjusted by adjusting the residence time of the brine solution in the cell and the orientation of the cell.

Description

FIELD OF THE INVENTIONThe present invention relates to water sterilization equipment, and more particularly, to an electrolytic cell for generating oxidant solutions that include ozone.BACKGROUND OF THE INVENTIONMaintaining the sterility of drinking water supplies is a major factor in reducing the health risks to the human population. While large metropolitan water systems can make use of highly toxic chlorine gas for sterilizing drinking water, such systems are impractical in remote locations which lack highly trained personnel and the equipment to maintain the systems. To be effective in rural settings, a system must be capable of running for long periods of time with little or no maintenance. In addition, the raw materials required by the system must be readily available.Systems based on the electrolytic production of chlorine and ozone based germicidal agents are particularly attractive. These systems require only electricity and common salt as raw materials. One such system is ...
