An electrode, electrochemical cell, and electrochemical processes are disclosed. The electrode is a porous, multi-layered electrode which can have an element in flexible, strip form wound around a central, usually flat plate core, which core may serve as a current distributor. In any form, each layer can be represented by a very thin, highly flexible metal mesh. This can be a fine, as opposed to a coarse, mesh which has extremely thin strands and small voids. The electrode will have an active coating. For utilizing this electrode, the cell in one form will be a monopolar cell providing upward, parallel electrolyte flow through the porous, multi-layered electrode. A representative cell can have such electrode at least substantially filling an electrode chamber. The cells can be contained in a cell box that will provide the desired flow-through relationship for the electrolyte to the electrode. In cell operation, electrochemical processes which can be carried out include metal ion oxidation or reduction, oxidation of organic substituents, nitrate reduction as well as salt splitting.

A bipolar battery having a consumable metal anode and being of the filter-press type is described. Internal battery contact is obtained by pressure connection transmitted virtually all, to completely, by end bulkheads. A multitude of adjoning cells can be placed together in a bipolar assembly cell stack. Yet the battery is compact and lightweight.

The present invention resides in a process and apparatus for the electrolytic production of strong solutions of halogen oxyacids, more specifically for the production of such acids having a normality of about 0. 1 to about 3. 6 from the corresponding alkali metal salts of such acids. The present invention comprises establishing a solution of the corresponding alkali metal salt having a molar concentration less than that at which precipitation of said salt occurs. An electrolytic cell is provided comprising an anode compartment containing an anode, a cathode compartment containing a cathode, and a middle feed compartment intermediate the anode compartment and cathode compartment. The feed compartment is separated from the anode compartment by a diaphragm and from the cathode compartment by a cation-selective membrane. Means are provided for introducing said alkali metal salt solution into said middle feed compartment and for applying a voltage between the anode and cathode. Under the influence of the applied voltage, the alkali metal ions migrate through the cation-selective membrane to the cathode, reacting with hydroxyl ions to form alkali metal hydroxide, and the oxyhalogen ions migrate through the diaphragm to the anode reacting with protons to form halogen oxyacid.

The present invention comprises a closed-loop filter system for continuously removing a metal hydroxide precipitate from an alkali metal hydroxide solution. The filter system comprises a filter having a filter surface and a plurality of small diameter openings in said surface. The alkali metal hydroxide solution is impacted onto said filter surface, metal hydroxide precipitate agglomerating on said surface. The filter surface openings have an average diameter effective for said agglomerating. Means are provided to remove the agglomerated precipitate from said filter surface, and to separate the agglomerated precipitate from the alkali metal hydroxide solution, the agglomerated precipitate having a particle weight to surface area ratio effective for said separation.

A pressure feeder for controlled addition of dissolvable agent into a flowing liquid has been designed which provides constant concentration of the agent in the treated liquid. This concentration is independent from the flow rate and the pressure of the liquid and also slugging of the agent at zero flow rate is avoided. A feeder according to the invention comprises a dissolution chamber connectable to a point of slightly increased pressure in the main circuit in which dissolution chamber the liquid is brought in controlled contact with stacked tablets of the agent. A linear weir controls the height of the liquid level in the dissolution chamber such that is proportional to the flow rate. The provision of a holding chamber for treated liquid which is connected to the dissolution chamber incorporates a gas volume that automatically adjusts for pressure differences and enables the liquid level in the dissolution chamber as well as the concentration of the agent in the treated liquid to be pressure independent. The holding chamber in turn is connected to a point of slightly decreased pressure in the main circuit.
