2. The apparatus of claim 1 wherein a liquid decontaminating agent is supplied to an inlet of said inlet cap to produce bubbles coated with a laminate of a liquid decontamination agent.
3. The apparatus of claim 2 further comprising:
an ozone generator to supply ozone as the gas to the second microporous diffuser; and
a liquid inlet to supply liquid to the second microporous diffuser to produce bubbles of ozone/air with a liquid laminate over the bubbles.
4. The apparatus of claim 3 wherein the liquid is hydrogen peroxide.
5. The apparatus of claim 2 wherein the first and second microporous diffusers are coupled to a plurality of additional microporous diffusers that are fed ozone and liquid, with the liquid comprising hydrogen peroxide.
6. The apparatus of claim 1 further comprising: an ozone generator, to supply ozone as the gas, coupled to the first microporous diffuser.
7. The apparatus of claim 6 wherein the first and second microporous diffusers are disposed at the bottom of the container.
8. The apparatus of claim 6 wherein the first and second microporous diffusers are coupled to a plurality of additional microporous diffusers that are fed ozone.
9. An apparatus for treatment of contaminated water comprises:
a container divided into a plurality of partially closed chambers by a plurality of walls each of which partially separates adjacent chambers;
wherein the container includes an inlet for receiving water into the container and an outlet for outputting water from the container;
a plurality of microporous diffusers arranged in the corresponding plurality of chambers, the microporous diffusers coupled to a gas feed arrangement and
wherein each microporous diffuser comprises: a first hollow cylindrical tube having a sidewall comprising a plurality of microscopic openings;
wherein of the microporous diffusers further comprise a second hollow tube having a sidewall comprising a plurality of microscopic openings, wherein the second hollow tube is disposed through the first tube; the tubes comprising an end cap to seal of the tubes; and an inlet cap disposed to provide inlets to interior portions formed by sidewalls of the tubes.
10. The apparatus of claim 9 wherein liquid decontaminating agent is supplied to an inlet of said inlet cap to produce bubbles coated with a laminate of a liquid decontamination agent.
11. The apparatus of claim 9 wherein the gas feed arrangement is coupled to an inlet of said inlet cap for feeding gas to the microporous diffusers.
12. The apparatus of claim 10 wherein the inlet cap includes a first fitting that permits the gas to be injected through the second tube in the microporous diffuser.
13. The apparatus of claim 10 wherein the inlet cap has a second fitting disposed to permit a liquid to be injected through a region defined between the first and second tubes of the microporous diffuser.
14. An apparatus comprises:
a container divided into at least two chambers by a wall that partially separates the two chambers, the container having an inlet at a first one of the chambers and an outlet at a second one of the chambers;
at least two microporous diffusers with one of the microporous diffusers disposed in a corresponding one of the at least two chambers of the container; and
wherein each microporous diffuser comprises:
a first hollow cylindrical tube having a sidewall comprising a plurality of microscopic openings;
a second hollow tube having a sidewall having a plurality of microscopic openings, the second tube being disposed through said first tube; and
an inlet cap disposed to provide inlets to interior portions formed by sidewalls of said tubes; and
fittings disposed to permit a liquid to be injected through a region defined between the first and second tubes of the microporous diffuser, and a gas to be injected within the region defined by the second tube.
15. The apparatus of claim 14 wherein the microporous diffusers produce bubbles coated with a laminate of a liquid decontamination agent.
16. The apparatus of claim 14 further comprising: an ozone generator coupled to the microporous diffusers to supply ozone as the gas.
17. The apparatus of claim 14 further comprising a liquid inlet also coupled to the first microporous diffuser to produce bubbles of ozone with air having a liquid laminate over the bubbles.
18. The apparatus of claim 17 wherein the liquid is hydrogen peroxide.
19. The apparatus of claim 14 wherein the first and second microporous diffusers are coupled to a plurality of additional microporous diffusers that are fed the gas and the liquid.
