Abstract: A method of treating a site containing perfluoroalkyl compounds (PFCs) is described. The method and apparatus treats the site with fine oxygen/ozone gas bubbles delivered with a hydroperoxide coating and solution which is activated by self-created temperature or applied temperature to raise the oxidation potential above 2.9 volts. Once begun, the reaction is often self-promulgating until the PFC is exhausted, if PFC concentrations are sufficiently elevated.

Abstract: A method for treating contaminants includes emitting plural streams of a fluid into a soil formation with the streams having different radii of influences in different directions. A directional microporous diffuser directionally emits microbubbles. Solenoid controlled valves control fluid or air distribution to inlets to provide directional control of bubble emanation.

Abstract: A method of treating a site containing contaminants and apparatus are described The method and apparatus sparges the site with an air/ozone gas stream delivered with a hydroperoxide, which is a substantial byproduct of a reaction of a contaminant present in the aquifer or soil formation with the ozone.

Abstract: 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.

Abstract: Permanganate is delivered by a device that allows delivery of the permanganate and an air-ozone mixture to a soil formation. The permanganate can be delivered as a coating over microbubbles including the air/ozone gas stream.

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: 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: Apparatuses for removal of volatile organic compounds in a soil formation include a microporous diffuser for injecting air and gaseous ozone as bubbles into water in the soil formation. The gaseous ozone is present at concentrations to effect removal of volatile organic compounds by the gaseous ozone reacting with the volatile organic compound(s). Injection of air and gaseous ozone is controlled by a timer to allow separation of bubbles by size. In various embodiments, a plurality of microporous diffusers may be controlled by a single timer or each of the plurality of microporous diffusers may be controlled by one of a plurality of timers.

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 ozonophilic bacteria at the site and introducing ozone to the site. The ozonophilic bacteria are introduced to the site if the ozonophilic 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 ozonophilic bacteria. Other oxidants can also be used.
