Abstract
An apparatus for treating liquid includes a tank having a water inlet for receiving water, a treated water outlet for outputting treated water and a flow path between the inlet and the outlet. An injection section of the tank is located along the flow path of the tank with an outlet toward a bottom of the tank. Ozonated liquid containing ozone microbubbles is injected through an injection manifold positioned within the injection section of the tank. The ozone microbubbles adsorb to impurities in the ozonated water. A separation section of the tank is positioned downstream of the outlet of the injection section. The separation section has a contact surface such that the ozonated water travels upward to contact the contact surface and such that at least a portion of the ozone microbubbles adsorb to the contact surface.
