ABSTRACT:
An aeration/mixing apparatus for a water body has a centrally located circular manifold and a plurality of evenly spaced, peripherally located air output connectors is positioned over a base plate. The manifold is supported a fixed distance above the plate and a plurality of microporous diffuser tubes inserted in the output connectors. The plate is at least coextensive with the tubes. The apparatus is placed in the bottom sediment of a water body and air supplied to the manifold. Air escaping from the diffuser tubes creates an upwelling convection current which mixes oxygen in the water by direct contact with the air. The base plate isolates the turbulent water at the diffuser assembly from the loose bottom sediment thereby preventing stirring of such sediments and concomitent resuspension of oxygen depleting nutrients into the water.
