ABSTRACT:
A liquid aeration device comprises a receiver chamber having bottom and side walls and arranged to receive liquid to be aerated and including an aerator wall in which orifice means is formed through which water to be aerated flows, a vertically disposed downcomer conduit atop which said receiver chamber is mounted and which is arranged to receive water by free fall flowing through said orifice means and downwardly into said downcomer and a vertically disposed riser conduit concentrically arranged about said downcomer conduit with its lower end in communication with the lower end of said downcomer conduit. Cutaway areas may be formed along the top edge of the aerator wall to accommodate flow of liquid through and over the wall and a plurality of receiver chambers may be mounted one above the other and arranged in vertically staggered relationship so that water entering the topmost receiver chamber is allowed to flow in tortious paths downwardly and through orifice means associated with each receiver chamber and ultimately into the downcomer tube disposed therebelow. Several stages of downcomer conduits and riser conduits may be provided by concentric conduits having successively larger diameters and of successively shorter heights so as to increase the degree of aeration which is achievable.
