A water purification system which filters particulates from the water and treats organic contaminats with ozone. The incoming contaminated water flow is divided, with half passing through each of two filter and ozone contact systems. Initially, each stream is passed though a sand separation device to remove large high density particulate mater, then through a multi-stage filter arrangement incorporating disposable filter cartridges. Ozone is injected into each stream leaving the filter system. The flow passes through elongated plug-flow tubing to assure optimum water/ozone contact, then enters a multi-compartment secondary contactor having a series of perforated baffle plates through which the water flows to assure complete ozone/water contact. Finally, each stream passes through a final filter stage, then the streams are combined and pass to storage or a purified water outlet. If desired, the entire flow can be passed through the combined ozone injection system, a selected filtration system and the water/ozone gas contact system.

[ We claim:] [1.] A water purification system which comprises:an inlet manifold for receiving pressurized water;at least two independent sand separation means for receiving water from said inlet manifoldat least two multi-stage filter trains, each for receiving of water from one of said sand separation means;each of said filter trains having a plurality of removable filter cartridges for filtering out predetermined contaminants in said water;a source of ozone;venturi means for receiving water from each of said filter trains and for injecting ozone from said source into said water;an elongated contact tube for receiving water from said venturi means and causing plug flow contact between said ozone and contaminants in said water;a multi-compartment secondary contactor for receiving water from said contact tube for assuring optimum ozone gas contact with remaining contaminants in said water;additional filter stages for receiving and filtering water from said secondary contactor; andmeans for combining water flow from all said additional filter stages and directing said combined water flow to a purified water outlet.
