Abstract:
1. An apparatus for treating liquid, comprising: a tank having a water inlet for receiving water to be treated and a treated water outlet for outputting treated water, the tank having a flow path between the water inlet and the treated water outlet; an injection section of the tank along the flow path of the tank, the injection section having an outlet toward a bottom of the tank; a source of ozonated liquid containing ozone microbubbles; an injection manifold positioned within the injection section of the tank, the injection manifold having a longitudinal axis with a plurality of fluid injection jets spaced at intervals along the longitudinal axis and aimed radially from the longitudinal axis for creating a turbulent flow, the jets injecting the ozonated liquid into the injection section of the tank to form an ozonated water, and at least a portion of the ozone microbubbles absorbing impurities in the ozonated water; and a separation section of the tank positioned downstream of the outlet of the injection section of the tank and upstream of the treated water outlet along the flow path; a series of angled baffles spanning between barrier walls and positioned within the separation section of the tank such that the flow path of the water to be treated must pass through and must be diverted by the angled baffles when flowing from the injection section to the separation section, each baffle defining a contact surface positioned at an acute angle in relation to the bottom of the tank in a section of the flow path having an upward direction of travel such that the ozonated water travels upward to contact the contact surface and such that at least a portion of the ozone microbubbles absorb to the contact surface terminating gas floatation of impurities such that impurities fall toward the bottom of the tank and back into the turbulent flow.
