Abstract
In a method of and apparatus for producing sub-micron bubbles in liquids, slurries, and sludges, gas is maintained on the interior of the gas permeable partition at predetermined pressure. Relative movement between the gas permeable partition and the surrounding material forms sub-micron sized bubbles in the liquid, slurry, or sludge.
