Abstract

An apparatus and method are disclosed for rapidly and efficiently dissolving gases in a liquid. A
diffuser, including a closed top hollow device, preferably a hollow conical, shaped frustum having a plurality of openings around the perimeter near the closed top is submerged in the liquid and rotated at relatively high speeds creating a centrifuge-pump.
When the rotating diffuser is located near the surface of the liquid, no additional gas is required in the dissolution process. When the device is submerged substantially below the surface or if a gas other than oxygen is to be dissolved, then additional gas must be pumped into the bottom opening of the rotating diffuser. This device can be used in oxygenating treated sewage water, removing impurities from liquids, and for oxygenating horticultural ponds to increase production.
