Abstract: A self-contained, self-sufficient system and method for purifying non-potable water to make the water potable is disclosed. The system comprises (a) means for oxidizing which treats the non-potable water by oxidizing organic substances, disinfecting the non-potable water by destroying parasites, bacteria and viruses, and causing coagulation of colloids, (b) means for filtering the treated non-potable water wherein oxidized organic substances, destroyed parasites, bacteria and viruses, and colloids are removed to provide potable water, and (c) means for optionally generating a biocide from dissolved salts when dissolved salts are present in the non-potable water. The system can also include means for contacting potable water generated by the system with a biocide. The system is self-contained and self-sufficient, requiring no external resources for the continuous operation thereof.

Abstract: An ozone generator is disclosed. The ozone generator includes a housing forming a tubular-shaped shell. A tubular ceramic electrode is suspended within the tubular-shaped shell of the housing. An end of the electrode protrudes from the tubular-shaped shell of the housing. The electrode, as suspended, forms a annular space of uniform width between the shell and the electrode, which space serves as the discharge gap. A Teflon.TM. retainer grips the end of the electrode protruding from the tubular-shaped shell of the housing. The retainer connects with the housing to maintain the electrode fixed in position within the tubular-shaped shell.
