ABSTRACT:
A gas diffuser for use in aeration treatment of water, sewage, industrial wastes and the like is provided. Gas is released from a plurality of vertical slot-shaped ports in a distribution tube. The gas released from said ports rises under the influence of buoyancy and impinges upon a frustro-conical distribution surface located above the distribution ports. The frustro-conical surface evenly disperses the gas to a shear edge whereupon small bubbles are created and violently mixed with the liquid to be treated. Drift control vanes are interposed in an equally-spaced relationship between the distribution ports to provide even distribution.
