Abstract

An electrochemical reactor for removing mining constituents from a fluid is disclosed. The electrochemical reactor includes a housing defining a flow path and a pump configured to continuously move fluid through the flow path at a flow rate. The electrochemical reactor also includes a power supply coupled to the housing, an anode and a cathode coupled to the power supply, and a controller configured to selectively engage the power supply power supply. The power supply applies an electrical potential between the anode and the cathode when engaged.

First claim

What is claimed is:

1. An electrochemical reactor for removing mining constituents from a fluid, comprising:
a housing including a plurality of channels defining flow paths, wherein each of the plurality of channels includes a top plate, a bottom plate, and a plurality of sidewalls coupling the top plate to the bottom plate, wherein the top plate, the bottom plate, and the plurality of sidewalls thereby enclose the flow paths;
a power supply coupled to the top plate and the bottom plate of at least one of the plurality of channels;
an anode and a cathode coupled to the power supply, wherein the top plate of the at least one of the plurality of channels is coupled to a current receiving lead of the power supply thereby forming the cathode, and wherein the bottom plate of the at least one of the plurality of channels is coupled to a current delivering lead of the power supply thereby forming the anode; and
a controller configured to selectively engage the power supply, wherein the power supply applies an electrical potential between the anode and the cathode when engaged.

2. The apparatus of claim 1 , the top plate of the at least one of the plurality of channels defining a first top plate and the bottom plate of the at least one of the plurality of channels defining a first bottom plate, wherein the first bottom plate is electrically and structurally coupled to a second top plate of a second channel.

3. The apparatus of claim 2 , wherein a second bottom plate of the second channel is coupled to the current receiving lead of the power supply thereby forming the cathode.

4. The apparatus of claim 1 , wherein the at least one of the plurality of channels includes an elongated member disposed along a longitudinal axis of the housing.

5. The apparatus of claim 4 , wherein the elongated member comprises a wire.

6. The apparatus of claim 4 , wherein the elongated member is positioned along a central axis of the at least one of the plurality of channels.

7. The apparatus of claim 1 , wherein the plurality of channels are distributed in a rectangular array within the housing.

8. The apparatus of claim 1 , wherein the plurality of channels are distributed in a hexagonal array within the housing.

9. The apparatus of claim 1 , wherein the at least one of the plurality of channels is electrically insulated from a second of the plurality of channels.

10. The apparatus of claim 9 , wherein the controller is configured to apply a first electrical potential within a first channel and a second electrical potential within a second channel.

11. The apparatus of claim 1 , further comprising a fluid disposed within the housing.

12. The apparatus of claim 11 , wherein the fluid includes a constituent.

13. The apparatus of claim 12 , wherein the constituent comprises an ion having an electrical mobility.

14. The apparatus of claim 13 , wherein the fluid includes a second ionic constituent having a second electrical mobility.

15. The apparatus of claim 12 , wherein the fluid includes a second constituent.

16. The apparatus of claim 1 , wherein the at least one of the plurality of channels includes a first region extending along a first length of the flow paths and a second region extending along a second length of the flow paths.

17. The apparatus of claim 16 , wherein the power supply is configured to apply a first current level in the first region and a second current level in the second region.

18. The apparatus of claim 16 , wherein the power supply is configured to apply a first potential in the first region and a second potential in the second region.

19. An electrochemical reactor for removing mining constituents from a fluid, comprising:
a housing including a plurality of channels defining flow paths, wherein each of the plurality of channels includes a top plate, a bottom plate, and a plurality of sidewalls coupling the top plate to the bottom plate, wherein the top plate, the bottom plate, and the plurality of sidewalls thereby enclose the flow paths;
a power supply coupled to the top plate and the bottom plate of at least one of the plurality of channels;
an anode and a cathode coupled to the power supply, wherein the top plate of the at least one of the plurality of channels is coupled to a current delivering lead of the power supply thereby forming the anode, and wherein the bottom plate of the at least one of the plurality of channels is coupled to a current receiving lead of the power supply thereby forming the cathode; and
a controller configured to selectively engage the power supply, wherein the power supply applies an electrical potential between the anode and the cathode when engaged.

20. The apparatus of claim 19 , the top plate of the at least one of the plurality of channels defining a first top plate and the bottom plate of the at least one of the plurality of channels defining a first bottom plate, wherein the first bottom plate is electrically and structurally coupled to a second top plate of a second channel.

21. The apparatus of claim 20 , wherein a second bottom plate of the second channel is coupled to the current delivering lead of the power supply thereby forming the anode.

22. The apparatus of claim 19 , wherein the at least one of the plurality of channels includes an elongated member disposed along a longitudinal axis of the housing.

23. The apparatus of claim 22 , wherein the elongated member comprises a wire.

24. The apparatus of claim 22 , wherein the elongated member is positioned along a central axis of the at least one of the plurality of channels.

25. The apparatus of claim 19 , wherein the plurality of channels are distributed in a rectangular array within the housing.
