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.

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.

Disclosed is a new form of reactive ozone and techniques for producing nanobubble suspensions of the reactive ozone. The bubbles entrap a high concentration of ozone, with the ozone orienting a net negative charge outwards and a net positive charge inwards.

Enhanced reactive ozone

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.

Directional microporous diffuser and directional sparging

Bubble generator devices to produce a fluid stream of bubbles are described. Apparatuses that include any of the described bubble generator devices to treat waste and/or frac-water are also described.

Nano-bubble generator and treatments

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.

Groundwater and subsurface remediation

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.

Soil and water remediation system and method

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.

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.

Permanganate-coated ozone for groundwater and soil treatment with in-situ oxidation

Method 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.

Deep well sparging

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.
