Abstract
A microporous diffuser includes a first elongated member including at least one sidewall having a plurality of microscopic openings. The sidewall defines an interior hollow portion of the member. The diffuser has a second elongated member having a second sidewall having a plurality of microscopic openings, the second member being disposed through the hollow region of the first member. The diffuser includes an end cap to seal a first end of the microporous diffuser and an inlet cap disposed at a second end of microporous diffuser for receiving inlet fittings.
Claims37
A microporous diffuser comprising:
- a first elongated member including at least one sidewall having a plurality of microscopic openings, said sidewall defining an interior hollow portion of said member;
- a second elongated member having a second sidewall having a plurality of microscopic openings, said second member being disposed through the hollow region of said first member;
- an end cap to seal a first end of the microporous diffuser;
- and
- an inlet cap disposed at a second end of microporous diffuser the inlet cap having a pair of openings to deliver a first fluid to the interior portions of the first member and a second fluid to interior portions of the second member.

A microporous diffuser comprising:
- a first hollow cylindrical tube coupled to a first inlet and adapted to be fed by a gas, the tube having a sidewall comprising a plurality of microscopic openings the openings having a diameter in a range of 1 to 200 microns;
- and
- a second hollow tube coupled to a second inlet and adapted to be fed by a liquid, the tube having a sidewall with a plurality of microscopic openings, the openings having a diameter in a range of 1 to 200 microns, with said first tube being disposed through said second tube and arranged such that gas injected into the first tube travels towards the sidewall of the second tube forming microfine bubbles laminated with the liquid;
- an end cap to seal first ends of said tubes;
- and
- an inlet cap disposed to seal second ends of said tubes and to support the first and second inlets to the interior portions formed between said tubes.
