ABSTRACT:
A gas treatment system for liquids can increase gas exposure and contact time. A liquid stream is directed into a vortex chamber (130). The vortex chamber (130) creates a downward spiral flow of the liquid stream forcing it into an upper end inlet (145) of a contact tank (114) and downward in the contact tank (114). When the liquid stream reaches a lower region (170) of the contact tank (114), a portion is drawn into a draw tube (120) while the other portion is drawn into a re-circulation system (160). In the re-circulation system (160), a gas injector system (166) entrains bubbles of a treatment gas into the liquid stream creating a re-circulated stream that is displaced into an upper region (168) in the contact tank (114). The portion drawn into the draw tube (120) then moves upwardly to a degassing chamber (146) wherein the treatment gas is separated from the liquid and delivered through an outlet (124) for use. Because the entrained bubbles are forced downwardly through the contact tank (114), and a portion of the liquid stream is re-circulated with additional entrained bubbles, the gas bubbles remain quite small and contact time is prolonged. Release of the treatment gas is further facilitated by positioning the degassing chamber (146) at an elevated position which promotes gas bubble expansion, combination and release.
