Abstract
A method and apparatus for using a combination of sonication and ozone to decontaminate pressurized water. The process includes pumping polluted water from a source, such as a creek, river, pond or the like. The water is transferred to a treatment container where it is dissolved air is removed via vacuum, sonication, or both. Ozone is then dissolved into the water to destroy or otherwise remove pollutants. Dissolved gasses are once again then removed from the water. The treated water may then be piped to a storage tank for subsequent use. The uninterrupted sequential transfer of water from the source, through a treatment container and to the storage tank may be accomplished automatically by way of electronic sensors, valves and pumps that are made to communicate with a central processor control unit.
