ABSTRACT:
A diffuser for dispersing gas bubbles into a liquid is formed of gas permeable material having a high surface tension at an interface with the liquid and a low surface tension in a region inward from the interface. The upstream region with the low surface tension resists liquid backflow, and the high surface tension of the interface keeps the bubbles small as they depart from the diffuser and enter the liquid.
