<p>An apparatus for dissolving at least one gas in a liquid comprises an eductor submerged in a liquid, desirably in combination with a high turbulence mixing device, so that synergistic results are obtained. The inlet portion of the eductor generally has an inward convergence towards a throat. The outlet portion of the eductor has an outward divergence. A diffuser which generally carrier the gas mixed with a liquid extends through the eductor inlet portion and through the throat portion into the outlet portion. In a desired embodiment, the diffuser is connected or attached to a high turbulence mixing device such as desirably, a flat plate orifice in a conduit. An injection tube extends through the flat plate orifice downstream into the conduit pipe and injects a gas into the liquid to produce a gasliquid mixture. The apparatus dissolves an exceedingly high amount of gas into a liquid and requires very low amounts of energy. In one aspect, the eductors may be placed vertically; in another aspect the eductors may be inclined within a tank, lagoon, and the like to impart a directed flow pattern thereto.</p> |
