摘要： A diffuser (1) for mixing and oxygenating water or other liquid with an airstream employs a self supporting microporous tubular membrane (11), arranged in a spiral or grid configuration, with openings which are at least equal to the diameter of the membrane (11), extending both horizontally and vertically between the circuits or grids of the diffuser (1). Gas, when forced through the tubular membrane (11), forms fine bubbles which agitate, oxygenate and entrain the surrounding liquid as it slowly rises through the openings. The tubular membrane (11) is flexible and is to be mounted on a manifold (14, 15) which connects it to a source of air or gas, and which may also impart buoyancy or serve as an anchor in the liquid.
