Abstract
Abstract An assembly of electrodes suitably for use in electrochemical processes, comprising a plurality of elongated conductive elements as electrodes arranged substantially in parallel in a vertical plane and spaced apart from each other. At least one elongated non-conductive element is interposed between every two adjacent conductive elements. Preferably, both the conductive and non-conductive elements are flexible and the assembly comprises a base fabric of non-conductive material and a plurality of conductive elements incorporated in said base fabric.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
131 words
A continuous process for the removal of solutes from an aqueous solution containing the same dissolved therein, said solutes being capable of forming insoluble materials depending upon the pH of the solution, which process comprises the steps of causing said aqueous solution to flow gravitationally downwards in the form of thin films over a vertical fabric of non-conductive material in which a plurality of elongated conductive elements are incorporated so as to be substantially horizontal parallel and spaced apart from each other and applying a potential to said conductive elements so as to produce a suitably steady pH distribution in the thin films of the solution flowing downwards over the fabric, whereby said solutes are insolubilized and deposited on predetermined zones of said fabric irrespectively of any anodic and cathodic reactions.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
23 words
A process in accordance with claim 1, wherein said conductive elements in said fabric are connected so as to provide a multi-bipolar system.
