Abstract:
1. An apparatus for treating water stored in a reservoir to remove contaminants, comprising: (a) means for receiving water to be treated through a feed line from the reservoir; (b) means for adding ozone at a controlled rate to the water to be treated in the feed line; (c) means for supplying hydrogen peroxide at a controlled rate to the water to be treated in the feed line, the means for supplying hydrogen peroxide includes a sensor probe adapted to determine an oxidation reduction potential of the water, whereby a rate of supply of hydrogen peroxide is dependent on the oxidation reduction potential; (d) a multicyclone unit configured to promote mixing of the ozone and the hydrogen peroxide with the water to be treated, the multicyclone unit including a water treatment chamber, the water treatment chamber including a filter disposed therein that is configured for removing insoluble oxidation product; and (e) a return line for returning treated water to the reservoir; wherein the means for adding ozone at a controlled rate includes a venturi valve which responds to a rate of flow of water by creating a vacuum in an ozone supply line, and wherein the multicyclone unit is located in the return line between the venturi valve and the reservoir.
