Abstract:
Polarizing conductive conduits are mechanically and electrically mounted to respective ones af a pair of electrodes to which a voltage source is connected to establish an electric field between the electrodes. Liquid to be purified is first passed through one or more of said conduits and then passed between said electrodes to precipate or coagulate materials contained in said liquid.
Abstract:
A method of installing a pool purifier is provided in which an existing water pipe in communication with the pool is used as a conduit for an electrical wire. The wire connects the pool purifier to a source of electricity located outside the pool to energize the pool purifier. A reel for installing the electrical wire through the water circulation line is also provided. The reel comprises a central housing and a tubular junction fitted to the housing. A spool of line is contained within a water tight chamber defined by the central housing. The other end of the tubular junction is fitted to a hole drilled in the water circulation line of a pool, and water from the circulation line is allowed to fill the chamber of the reel. The spool floats freely within the chamber as line unwinds from it and passes through the tubular junction to the water circulation line and out into the pool. The electrical wire is then fastened to the end of the line and pulled back through the water circulation line.
Abstract:
A method and apparatus for destroying organic compounds is described. The apparatus utilizes a mixture of oxidants to "burn" the organic compound. The oxidants can be generated in a separate apparatus and then added to the organic compound. If the organic compound is present in the form of an aqueous solution, the oxidants can be generated in the aqueous solution itself.
Abstract:
A method and an apparatus for treating water by passing the water through an electrolytic bath provided with an anode and a porous cathode. The water is qualified by the decomposition and the reduction of chloride compounds in the water while the water passes through the porous cathode that occupies full area of a cross section of the flow path of the water.
Abstract:
A device for precipitating metals out of a liquid by applying an electric field to a flowing liquid makes use of two spaced apart insulating plates provided with mutually facing grooves, and two pieces of metal flat stock sealably mounted between the plates in spaced apart relationship. The liquid flows into and out of the space between the pieces of flat stock through inlet and outlet openings in one of the insulating plates. The pieces of flat stock function as electrodes and are respectively connected to the output terminals of an electric power supply.
Abstract:
An improved electrolytic system for treating aqueous solution which passes the solution along an inner helical insulator wrapped around a centrally located anode solid rod and an enclosing inner cathode tube, then along a cathode tube wrapped or spaced with another helical insulator and an enclosing outer anode tube. The solid rod can be replaced with an innermost tube in order for the solution to initially pass through a cathode portion of the system. Also, the innermost cathode tube can have a plurality of apertures as passageways for the solution. A DC voltage is applied, in one direction or in sequential fields of different directions across the plurality of metal rods and tubes, thereby effectively removing both suspended materials and dissolved solids from the aqueous solution to be treated. The power supply required from the DC voltage can be decreased by treating specified tubes or rods. Various materials may be removed from waste water, either with the improved apparatus and method of the new apparatus of this invention or with the Liggett device, including removal of organics, or rendering plant fats, colloids, salts or the recovery of certain metals including gold.
Abstract:
System for softening and dealkalizing water by feeding said water to both chambers of an electrolytic cell which chambers are separated by a cation exchange membrane, applying DC voltage to the electrodes of the cell, at intervals, reversing the applied polarities, and drawing soft dealkalized water from the anodic compartments.
Abstract:
The treater has one of its electrodes rotating within the treating chamber, and the other electrode is specially configured to not only serve as means for cooperating in the production of the electric field, but also to serve as an inlet nozzle for incoming fluid into the treating chamber. The inlet nozzle of the specially shaped electrode is directed toward the rotating electrode and is located in closely spaced proximity thereto so that the rotating electrode is cleaned by the jet action liquid issuing from the other electrode.
Abstract:
The known method of removing heavy metal and cyanide ions from plating waste solutions wherein the solution is passed through flow-through, high surface area electrodes to precipitate heavy metal ions and to oxidize cyanide is improved through the use of a novel stationary bed dual electrode capable of reducing heavy metal and cyanide ion concentration. The process promotes economical electrolytic purification because it can be accomplished at relatively high current efficiencies. The metals removed from the solutions are recovered in a concentrated form suitable for purification.
Abstract:
Prior art electrolysis cells used for producing chlorine for sanitizing and sterilization purposes deteriorate due to accumulation of scale on the electrodes thereof. This problem is solved by an improved cell comprising an outer electrode having an in-facing surface which falls generally on a first cylindrical surface and an inner generally coaxial electrode having an out-facing surface which falls generally on a second cylindrical surface, the second cylindrical surface falling inward radially of the first cylindrical surface, the outer and inner electrodes being longitudinally coextensive for at least a substantial portion thereof. The inner and outer electrodes are rotated relative to one another. An abrading structure is mounted to one of the electrodes with an abrasive portion thereof in abrasive contact with the other of the electrodes. The abrading structure is electrically insulated from at least one of the electrodes. The electrodes are supported in electrically insulating relation relative to one another within a cell cavity.
