ABSTRACT:
An apparatus and method for treating water with ozone. An outer conduit forms a continuous, vertical loop. A pump is connected to the bottom of the loop and pumps water about the loop from the bottom towards a first side. An opening admits ozone into the outer conduit. There is an outlet for gases near the top of the loop. An inner conduit within the outer conduit is spaced - apart therefrom to form a passageway for water therebetween. The inner conduit has an inlet between the opening for ozone and the outlet for gases and an outlet within the outer conduit on the second side of the loop. Some of the water is diverted into the inlet of the inner conduit. A flow of water at reduced linear velocity is permitted through the passageway into the outer conduit. Ozone released at the outlet of the inner conduit flows upwardly through the outer conduit in counterflow to the water therein to increase the amount of ozone dissolved in the water.
