Soil and water remediation system and method
Method for treating contaminants at a site, especially a deep well site, includes delivering a first stream of a first gas to a first port of a laminar microporous diffuser and delivering a second stream of a second gas to a second port of the laminar microporous diffuser to effect mixing of the first and second streams of gases within the laminar microporous diffuser.
1. Deep well sparging method, comprising:
delivering a first gas to a first cylinder, and
delivering a second gas to a second cylinder of a microporous material, the first and second cylinders being concentric with one another.
2. The method of claim 1 , further comprising:
coupling a first inlet port to the first cylinder and coupling a second inlet port to the second cylinder.
3. The method of claim 2 further comprising coupling a first compressor to the first inlet port and coupling a second compressor to the second inlet port.
4. The method of claim 3 , further comprising coupling an ozone generator to supply ozone to the first compressor and coupling a pump to supply air to the second compressor.
5. The method of claim 4 , further comprising arranging the ozone generator and the pump so that the ozone generator siphons the ozone to the first or second cylinder.
6. The method of claim 5 , further comprising supplying the ozone at a flow rate of 0.5-50 cubic feet per hour (CFH) and supplying the air at a flow rate of 2-20 CFH.
7. The method of claim 1 , the first gas and second gas being mixed to form gas bubbles, at a well site.
8. The method of claim 1 , further comprising:
disposing the first and second cylinder into a well that is contaminated with various contaminants.
9. The method of claim 8 , further comprising disposing the first and second cylinder in the well at a depth exceeding a depth that produces back pressure on an ozone generator connected to the first or second cylinder.
10. The method of claim 8 further comprising disposing a casing with an inlet screen and an outlet screen in the well.
11. The method of claim 10 wherein the inlet screen and outlet screen promote recirculation of water into the casing and through the well.
12. The method of claim 9 , further comprising disposing the first and second cylinder in the well at a vertical depth in excess of 180 feet from the surface of the earth.
13. The method of claim 1 , wherein delivering the first gas comprises delivering air to the first cylinder and wherein delivering the second gas comprises delivering ozone to the second cylinder.
14. The method of claim 1 wherein delivering the first gas comprises delivering ozone to the first cylinder and wherein delivering the second gas comprises delivering air to the second cylinder.
15. The method of claim 1 , further comprising emitting bubbles of encapsulated ozone and/or air from the first and/or second cylinder.
16. The method of claim 15 wherein the bubbles or encapsulated ozone and/or air extract a vapor phase fraction of a volatile compound.
17. The method of claim 1 , wherein delivery of the first and second gases mixes the gases within the first and second cylinders.
18. The method of claim 1 , the first and/or second cylinder emitting bubbles having a size in a range of 0.5 to 200 microns.
19. The method of claim 1 further comprising including a pump to supply nutrients to the first cylinder or the second cylinder.
