Abstract

A method of treating fluids, including for recovery of water apart from impurities or undesired matter, utilizes application of shock waves to the fluids.

First claim

What is claimed is:

1. A method of removing contaminants from liquid comprising:
providing a liquid including contaminants into a containment;
applying acoustic pressure shock waves to the liquid with a shock wave applicator comprising a reflector guiding the liquid to push contaminants downward in a direction of gravity; and
collecting decontaminated liquid from the containment.

2. The method of claim 1 , wherein the contaminants include particulate matter.

3. The method of claim 2 , wherein the contaminants include particulates selected from the group consisting of sand, dissolved solids and minerals.

4. The method of claim 3 , further comprising providing gas bubbles to the liquid including contaminants.

5. The method of claim 2 , wherein the liquid is water.

6. The method of claim 5 , further comprising providing gas bubbles to the liquid including contaminants.

7. The method of claim 2 , further comprising providing gas bubbles to the liquid including contaminants.

8. The method of claim 1 , wherein the contaminants include one or more of soluble organics, microbial pollutants, dissolved gases and radioactive materials.

9. The method of claim 8 , wherein the liquid is water.

10. The method of claim 8 , further comprising providing gas bubbles to the liquid including contaminants.

11. The method of claim 1 , further comprising providing gas bubbles to the liquid including contaminants.

12. The method of claim 11 , further comprising removing at least one of froth and foam from a surface of the liquid.

13. A system for removing contaminants from liquid comprising:
a liquid containment;
one or more acoustic pressure shock wave applicators including a reflector guiding the liquid, positioned to apply shock waves into the containment in a direction of gravity; and
at least one of a channel and an outlet coupled to the containment for receiving decontaminated liquid.

14. The system of claim 13 , further comprising a contaminated liquid inlet into the containment.

15. The system of claim 14 , further comprising a gas feed coupled to the containment.

16. The system of claim 15 , further comprising a liquid surface scraper.

17. The system of claim 13 , further comprising a sludge outlet from the containment.

18. The system of claim 17 , further comprising a gas feed coupled to the containment.

19. The system of claim 13 , further comprising a gas feed coupled to the containment.

20. The system of claim 19 , further comprising a liquid surface scraper.
