Deep well sparging

1. A method comprises:

delivering a first stream of a first gas to a first port of a microporous diffuser; and

delivering a second stream of a second gas to a second port of the microporous diffuser to effect mixing of the first and second streams of gases within the microporous diffuser.

2. The method of claim 1 wherein the microporous diffuser comprises:

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 and coupled to the first inlet port;

a second elongated member having a second sidewall having a plurality of microscopic openings, said second member being disposed through the interior hollow region defined by the first member and coupled to the second inlet port;

an end cap to seal a first end of the microporous diffuser.

3. The method of claim 2 wherein the first and second elongated members are cylinders and the second elongated member is disposed concentric to the first elongated member.

4. The method of claim 2 wherein the second elongated member is one of a plurality of second elongated members disposed through the first elongated member.

5. The method of claim 4 wherein the plurality of second elongated members posed through a substantial portion of a length of the first elongated member, and with the second elongated members including caps to terminate ends of the second elongated members.

6. The method of claim 1 wherein an ozone generator is coupled to the first inlet.

7. The method of claim 6 wherein the ozone generator and a pump to supply air are arranged so that the ozone generator works under a siphon condition to efficiently deliver ozone to the microporous diffuser.

8. The method of claim 1 wherein the microporous diffuser is disposed in the well at a depth that exceeds a depth that produces a back pressure on an ozone generator that would effectively reduce the efficiency of ozone production by the ozone generator by 50%.

9. The method of claim 1 further comprising disposing the microporous diffuser in a well.

10. The method of claim 1 wherein the microporous diffuser emits microbubbles having a size in a range of 1 to 200 microns.

11. The method of claim 1 wherein the microporous diffuser is disposed at a vertical depth in excess of 180 feet from the surface of the earth.

12. A method comprises:

delivering a first stream of a first gas to a first inlet port of a microporous diffuser;

delivering a second stream of a second gas to a second inlet port of the microporous diffuser, with the first inlet port coupling to a first region of the microporous diffuser defined by a first member having a plurality of microscopic openings and a second member having a plurality of microscopic openings, and the second inlet port coupling to a second region of the microporous diffuser defined by the second member, to effect mixing of the first and second streams of gases within the first region of the microporous diffuser.

13. The method of claim 12 wherein the microporous diffuser further comprises:

an end cap to seal a first end of the microporous diffuser.

14. The method of claim 13 wherein the first and second members are cylinders and the second cylindrical member is disposed concentric to the first cylindrical member.

15. The method of claim 13 wherein the second member is one of a plurality of second members disposed through the first member.

16. The method of claim 13 further comprising:

feeding ozone and air to the first and second inlet ports, respectively.

17. The method of claim 13 further comprising:

feeding ozone and air to the first and second inlet ports, respectively, so that a ozone generator that supplies the ozone works under a siphon condition to efficiently deliver ozone to the microporous diffuser.

18. The method of claim 16 wherein the microporous diffuser is disposed in a well at a depth that exceeds a depth that produces a back pressure on an ozone generator that supplies the ozone, the back pressure being sufficient to otherwise reduce the efficiency of ozone production by the ozone generator by 50%.

19. The method of claim 13 further comprising:

disposing the microporous diffuser in a well.

20. The method of claim 13 wherein delivering a first stream of a first gas and delivering a second stream of a second gas provides microbubbles having a size in a range of 1 to 200 microns to be emitted from the microporous diffuser.

21. The method of claim 13 wherein the microporous diffuser is disposed at a vertical depth in excess of 180 feet from the surface of the earth.

22. A method comprises:

emitting microbubbles of air and ozone by:

delivering a first stream of ozone gas from an ozone generator to a first inlet port of a microporous diffuser, the ozone flowing through peripheral regions of the microporous diffuser;

delivering a second stream of air to a second inlet port of the microporous diffuser, the air flowing through central regions of the microporous diffuser and diffusing out towards the peripheral regions of the microporous diffuser, with the flowing air causing the ozone generator to operate under a siphon condition to efficiently deliver the ozone.

23. The method of claim 22 wherein the microporous diffuser comprises:

a first member having a plurality of microscopic openings;

an end cap to seal a first end of the microporous diffuser; and

a second member having a plurality of microscopic openings, with the first inlet port coupling to a first region of the microporous diffuser and the second inlet port coupling to a second region of the microporous diffuser defined by the second member to effect mixing of the first and second streams of gases within the first region of the microporous diffuser.

24. The method of claim 23 wherein the first and second members are cylinders and the second cylindrical member is disposed concentric to the first cylindrical member.

25. The method of claim 23 wherein the second member is one of a plurality of second members disposed through the first member.

26. The method of claim 22 further comprising:

disposing the microporous diffuser within a well.

27. The method of claim 26 wherein the microporous diffuser is disposed in the well at a depth that exceeds a depth that produces a back pressure on the ozone generator.

28. The method of claim 22 wherein microbubbles having a size in a range of 1 to 200 microns are emitted from the microporous diffuser.

29. The method of claim 22 wherein the microporous diffuser is disposed at a vertical depth in excess of 180 feet from the surface of the earth.
