Title: Water treatment system

Abstract: An apparatus for treating water stored in a reservoir to remove contaminants has a feed line for receiving water and a by-pass valve that controls the flow of water through the feed line. A venturi valve responds to the rate of flow of water through a flow line by creating a vacuum in a supply line from an ozone generator, the extent of the vacuum created being dependent on the rate of flow, to add ozone at a controlled rate to the water to be treated. A sensor probe measures the oxidation reduction potential of the water, to supply hydrogen peroxide to the water at a controlled rate dependent on the oxidation reduction potential level. The ozone and the hydrogen peroxide are mixed with the water in a multicyclone unit to allow a peroxone reaction to occur that treats the water, and the treated water is returned to the reservoir.
