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.
Claims20
A method of treating a site comprises:
- sparging the site with an air/ozone gas stream, and delivering a hydroperoxide, which is a substantial byproduct of a reaction of a contaminant present in an aquifer or soil formation at the site with the ozone.
An apparatus for treating subsurface water comprises:
- at least one microporous diffuser disposed in the subsurface water to deliver at least a first one of a first and second fluids with one of the fluids forming a coating over the other of the fluids;
- an ozone generator;
- an air compressor and compressor/pump control mechanism to deliver ozone (O3) from the ozone generator to the microporous diffuser as one of the fluids;
- a source of the liquid hydroperoxides, the liquid hydroperoxide selected from the group consisting of formic peracid, hydroxymethyl hydroperoxide, 1-hydroxylethyl hydroperoxide, and chloroformic peracid or their derivatives;
- and
- a feed mechanism to deliver the selected liquid hydroperoxide to the microporous diffuser as the second one of the fluids.
