Abstract
In a method of and apparatus for producing sub-micron bubbles in liquids and slurries, gas is maintained on the interior of the gas permeable partition at predetermined pressure. Relative movement between the gas permeable partition and a liquid forms sub-micron sized bubbles in the liquid.
Claims7
An apparatus for producing sub-micron bubbles in liquids and slurries comprising:
- a quantity of liquid;
- a disk-shaped hollow chamber positioned in the liquid and including a gas permeable partition engaging the liquid;
- the gas permeable partition comprising a liquid engaging surface;
- the gas permeable partition comprising pores having diameters between about 0.1 microns and about 2.0 microns;
- apparatus for maintaining gas within the interior of the hollow chamber at a predetermined pressure sufficient to cause gas flow through the gas permeable partition while preventing liquid flow therethrough;
- and
- apparatus for causing relative movement between the gas permeable partition and the liquid in a direction extending across the liquid engaging surface.
