Filed:

Jul 31, 2001

Appl. No.:

09/920453

Inventors:

Edward C. Weakly - Morrison CO
Joseph N. Ignat - Cheyenne WY
Henry L. DiCamillo - Pahrump NV

Assignee:

Hydro-Met of Colorado, Inc. - Littleton CO

International Classification:

B01J 1908

US Classification:

42218604, 204671, 204665

Abstract:

An apparatus and process for recovering metals from aqueous solutions by passing an aqueous solution, which contains dissolved metals, into a space between two elongated electrodes of a treatment chamber. A very high voltage electric field is created in the treatment chamber and is accompanied by a very small trickle current charge to enhance adsorption, polarization, ion exchange or to otherwise agglomerate the dissolved metal, which is then recovered by filtering, adsorbing, exchanging or otherwise separating the metal from the water.

International Classification:

C02F 1461

US Classification:

205742

Abstract:

A system and process for removing metal from a directed flow of an aqueous solution by exposing the directed flow to a high voltage electrical field in the direction of the directed flow. In one embodiment, seven electrode chambers are provided, each connected in fluid communication end-to-end, and each having an electrode encapsulated by a layer of an electrically insulating material. Either DC or AC (preferably 60 Hertz) current may be used. Each electrode is surrounded by a grounded stainless steel lined PVC hollow tube, and a flow passageway is formed between the inner wall of the hollow tube and the outer layer of insulating material. The aqueous solution flows through the flow passageway, thereby being exposed to the high voltage electrical field adjacent to the electrode. The flow is directed into two tubular secondary grounds. Each ground is connected in flow communication end-to-end and has a quantity of stainless steel wool through which the flow is directed.
