Abstract

A liquid remediation system is disclosed comprising a reaction chamber having an inlet in communication with a source of liquid. A pump directs the liquid through the reaction chamber. A reactive medium, that chemically reacts with a contaminant is dispersed throughout the reaction chamber. At least one discharge loop may direct the liquid back to the source from the reaction chamber after the liquid has undergone a level of remediation. Also disclosed is a method of remediating a liquid. In the method a reaction chamber is provided, having an inlet in communication with a source of liquid. The liquid is directed through the reaction chamber by a pump. A contaminant in the liquid is chemically reacted with a reactive medium that is dispersed throughout the reaction chamber. The liquid is then directed back to the source from the reaction chamber through at least one discharge loop after the liquid has undergone a level of remediation.

Claims

1. A liquid remediation system, comprising:

a) a reaction chamber, defined by a well casing, having an inlet in communication with a source of liquid;

b) a pump for directing the liquid through the reaction chamber;

c) a reactive medium, that chemically reacts with a contaminant, dispersed as a slurry throughout the reaction chamber; and

d) at least one discharge loop for directing the liquid back to the source from the reaction chamber after the liquid has undergone a level of remediation.

2. The liquid remediation system of claim 1, wherein the reaction chamber further comprises an upper reaction chamber and a lower reaction chamber opening into the upper reaction chamber.

3. The liquid remediation system of claim 2 wherein the upper reaction chamber forms at least one horizontal extension that extends along a plane that is substantially perpendicular to the lower reaction chamber.

4. The liquid remediation system of claim 3, wherein the upper reaction chamber further comprises at least one vertical extension that is perpendicular to the horizontal extension and is in communication with the horizontal extension at an end of the horizontal extension opposite the lower reaction chamber opening.

5. The liquid remediation system of claim 2, wherein the upper reaction chamber further comprises:

a) a horizontal extension;

b) a conduit, being in communication with the lower reaction chamber and extending into the horizontal extension; and

c) a plurality of openings in a bottom side of the conduit for initially directing the liquid in a downward direction inside the horizontal extension.

6. The liquid remediation system of claim 2, wherein the upper reaction chamber forms a cross configuration.

7. The liquid remediation system of claim 2, wherein the upper reaction chamber forms a T configuration.

8. The liquid remediation system of claim 2, wherein the upper reaction chamber forms a horizontal configuration.

9. The liquid remediation system of claim 2, wherein the pump includes a discharge portion that is equipped with a slurry suspending nozzle.

10. The liquid remediation system of claim 1, further comprising at least one recirculation pipe having one end in communication with the reaction chamber, and another end proximate to the inlet.

11. A method of remediating a liquid, comprising the steps of:

a) providing a reaction chamber, defined by a well casing, having an inlet in communication with a source of liquid;

b) directing the liquid through the reaction chamber by a pump;

c) chemically reacting a contaminant in the liquid with a reactive medium that is dispersed as a slurry throughout the reaction chamber; and

d) directing the liquid back to the source from the reaction chamber through at least one discharge loop after the liquid has undergone a level of remediation.

12. The method of claim 11 wherein the reaction chamber further comprises an upper reaction chamber and a lower reaction chamber opening into the upper reaction chamber.

13. The remediation method of claim 12, wherein the upper reaction chamber forms a horizontal extension that is substantially perpendicular to the lower reaction chamber.

14. The remediation method of claim 12, wherein the upper reaction chamber further comprises a vertical extension in communication with the horizontal extension at an end of the horizontal extension that is opposite the lower reaction chamber opening.

15. The remediation method of claim 12, wherein the upper reaction chamber further comprises:

a) a horizontal extension;

b) a conduit, being in communication with the lower reaction chamber and extending into the horizontal extension; and

c) a plurality of openings in a bottom side of the conduit for initially directing the liquid in a downward direction inside the horizontal extension.

16. The remediation method of claim 12, wherein the upper reaction chamber forms a cross configuration.

17. The remediation method of claim 12, wherein the upper reaction chamber forms a T configuration.

18. The remediation method of claim 12, wherein the upper reaction chamber forms a horizontal configuration.

19. The remediation method of claim 11, further comprising the step of recirculating the liquid through a recirculation pipe having one end in communication with the reaction chamber, and another end proximate to the inlet.

20. The remediation method of claim 11, wherein the pump includes a discharge portion that is equipped with a slurry suspending nozzle.

21. A liquid remediation system, comprising:

a) a reaction chamber, defined by a well casing, having an inlet in communication with a source of liquid;

b) a pumping means for directing the liquid through the reaction chamber;

c) a reactive medium, that chemically reacts with a contaminant, dispersed as a slurry throughout the reaction chamber; and

d) at least one discharge outlet for allowing the liquid out of the system after the liquid has undergone a level of remediation.
