Abstract: A method for treating contaminates includes delivering a stream of a fluid to a directional microporous diffuser that has a sidewall with microscopic openings and has a partitioned interior region to effect discharge of microbubbles from less than the entire sidewall portion of the directional microporous diffuser at any particular interval of time. The directional microporous diffuser described include an elongated member providing the sidewall, the sidewall defining an interior portion of said member and coupled to the first inlet port and a partition member that divides the interior of the elongated member into plural, mutually isolated regions. End caps are disposed to seal ends of the directional microporous diffuser.

Abstract: Method and apparatus for treating contaminants on 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.

Abstract: Remediation for groundwater, soil, sediment bodies, bodies of water, tanks, pipes, and their surrounding areas are described. Remediation includes treating a site contaminated with toxic organic compounds by assessing for the presence or absence of suitable ozonphilic bacteria at the site and introducing ozone to the site. The ozonphilic bacteria are introduced to the site if the ozonphilic bacteria are not present or not present in sufficient quantities in the site. Ozone is introduced to the site in an amount sufficient to stimulate growth of the suitable ozonphilic bacteria. Other oxidants can also be used.

Abstract: A method and apparatus for hydrocarbon recovery and/or treatment of frac water includes introducing a volume of water into a formation, recovering the introduced water, with the recovered introduced water further comprising suspended hydrocarbon product. The recovered liquid is treated to remove substantial amounts of the suspended hydrocarbon product, provide the treated recovered liquid with a ORP in a range of 150 mv to 1000 mv, and partially desalinated, and is either re-introduced as treated recovered liquid with the ORP into a formation to assist in recovery of additional hydrocarbon deposits in the formation, or is stored to reduce the ORP and then subsequently discharged into surface waters.

The apparatus and method introduces at a first location treatment materials at concentrations to effect removal of contaminants into a formation and withdraws fluid from a second location that is spaced from the first location feeding withdrawn fluid back to the first location.

Abstract: A method for treating contaminates includes emitting plural streams of a fluid into a soil formation with the streams having different radii of influences in different directions. A direction microporous diffuser includes a holder member having plural compartments and plural hollow, elongated members having porous sidewalls, the plural hollow, elongated members supported in the plural compartments of the holder member with each hollow, elongated member including a an inlet port at a first end of the elongated member and second end of the elongated member being sealed.

Abstract: Apparatus and method for introducing a first fluid of a first oxidative/reductive potential type into a first zone of a site and introducing a second fluid of a second, different oxidative/reductive potential type into a second zone of the site, with the second zone and the first zone adjacent each other to efficiently remove contaminants from groundwater and surrounding soils.

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.

Abstract: A diffuser useful for sparging to remove contaminant in situ is described. The diffuser includes a first elongated member having a sidewall with a first portion of the length of the sidewall being microporous, and a second portion of the length of the sidewall having well screen sized openings with the first elongated member defining an interior hollow portion of the diffuser, 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 and a third elongated member having a third sidewall having a plurality of microscopic openings, said third member being disposed coaxial with the first and second members. An end cap is disposed to seal a first end of the third elongated member, and being in contact with the second elongated member forms a chamber.
