NOVELTY - The liquid purification system comprises a chamber into which liquid to be purified is delivered, an ozone generator (16) that generates ozone for mixture with the liquid in the chamber, a supply line, and nozzles. The ozone generator comprises a surface discharge device that creates ozone from air. The surface discharge device is a dielectric barrier discharge device comprising first and second electrodes that are separated by a dielectric material, and generates plasma when an electric potential is applied across the electrodes. The chamber comprises a liquid tank (12).    USE - The system is useful for purifying a liquid such as water.    ADVANTAGE - The system allows rapid and effective purification of the liquid with high quality and without impurities thus removing harmful agents and pathogens.    DETAILED DESCRIPTION - The liquid purification system comprises a chamber into which liquid to be purified is delivered, an ozone generator (16) that generates ozone for mixture with the liquid in the chamber, a supply line, and nozzles. The ozone generator comprises a surface discharge device that creates ozone from air. The surface discharge device is a dielectric barrier discharge device comprising first and second electrodes that are separated by a dielectric material, and generates plasma when an electric potential is applied across the electrodes. The chamber comprises a liquid tank (12) in which the liquid is held. The nozzles deliver the liquid into the chamber as a mist of fine droplets. The supply line delivers the ozone from the ozone generator to a bottom of the tank and to the mist so that ozone percolates up through the liquid. The droplets have diameters of 500 nm to 1 mm. The ozone generator comprises multiple surface discharge devices that are provided within the chamber. The chamber comprises interior walls that form closed gas channels through which air and ozone flow to the mist. Each gas channel has an inlet (18) and an outlet (34). The surface discharge devices are adapted to generate an ozone flow that flows to the mist, are provided on interior surfaces of the gas channels, and are positioned between the inlet and outlet. The inlet is positioned inside and outside of the chamber. The outlet is positioned within the chamber near the nozzles. An INDEPENDENT CLAIM is included for a method of purifying a liquid.
