Abstract:
This process can be carried out in an electrolytic cell which is non-partitioned or partitioned by at least one separator and has at least one porous electrode. The electrolyte enters parallel to the surface of the electrode and is forced by at least one restriction point to flow through the porous electrode parallel to the flow of charge.
Abstract:
An improved water purification system. The system utilizes an electrolytic cell and maintains a generally constant current flow through the electrolytic cell when the electrical resistance of water being treated by the cell varies. The relationship between current flow through the electrolytic cell and the temperature of water moving through the cell can generally be represented in linear graphical form.

The electrode comprising a plurality of metallic filaments consisting of carbon fibers coated with a metal, each of the metallic filaments being in electrical contact with at least several of the other metallic filaments for transmitting an electrical potential substantially throughout the electrode when the electrode is in use in the reactor.
Abstract:
The invention provides an electrode for use in an electrochemical reactor. The electrode comprising a plurality of carbon fibers in close proximity to one another, each of the fibers being in electrical contact with at least several of the other carbon fibers for transmitting an electrical potential substantially throughout the electrode when the electrode is in use in the reactor.
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.
Abstract:
An arrangement is provided for moving at least one aluminum anode with respect to a cathode, to maintain a fixed determined distance between the anode and cathode. An emulsion or contaminated water to be treated is run in the region between the electrodes, and means are provided for preferably running the emulsion or water along the aluminum anode before it reaches the space between the electrodes. The flock is then removed from the resultant flocculated liquid.
Abstract:
The conformation of the apparatus is broadly that of a shell-and-tube heat exchanger that can be of the single pass or multipass variety, and it can have substantially straight or bent tubes, including tubes with return bends. However, in this apparatus tubes are electrodes, and they are microporous. Electrode means of polarity opposite the tubes are provided; e.g., in the form of one or more charged heads or elements between such head or heads and the tube ends proximate thereto. Preferably the counter electrodes actually extend into the tubes. Appropriate fluid inlets and outlets and electrical terminals are provided.
