Abstract:
This invention provides an electrochemical water treatment device for producing hydroxyl free radicals and decomposing by oxidation chemical substances dissolved in water. It utilizes a novel electrode which is capable of operation at sufficiently positive anodic potential to produce hydroxyl radicals.
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:
Water purification is accomplished in a swimming pool, spa or decorative pool body of water by adding salt in quantities sufficient to make the water slightly conductive and by circulating that water through the electric field between a pair of electrode plates where the dissociated ions of salt and water are converted to oxidizing agents capable of destroying organic matter and are converted to substances that can be removed in such a mechanical filtration system. That process results in economical and effective purification which is augmented in one form of the invention by the inclusion in the water circulation path of dissimilar metals which aid in the destruction of organic matter. The process is facilitated by the use of a special electrochemical processing unit in which the electrode dissociation is accomplished.

Abstract:
A purification unit includes an electrolytic cell adapted to hold a body of water to be purified and provided with two electrically insulated electrodes, a pump supplying the water to be purified to the cell through a filter and driving purified water out of the unit, a power supply for supplying electrolyzing current to the electrodes, a control circuit which generates a sensible signal indicative of the operating conditions of the pump, the power supply, and the filter, and a housing which encloses the cell, the pump, the power supply, and the control circuit. The housing is partly received in a container for the raw water. The portion of the housing projecting from the container carries a discharge spout for purified water, a connector for an external source of current, and the signal display elements of the control circuit.
Abstract:
An electrostatic water treatment system in which the high voltage d.c. supply for the charging electrode is alternately turned on and off at lower and upper voltage limits and is turned off whenever the current exceeds the desired value. The alternating voltage produced by the on-off operation of the high voltage supply is utilized to check the control circuit and provide an indication whenever the circuit is operating improperly.
Abstract:
There is provided an improved apparatus and method for relatively low volume batch treatment and disposition of sewage or toilet wastes especially from passenger vehicles such as railway cabooses, motor houses, or other passenger-carrying vehicles. The apparatus is characterized by the ability to operate without moving parts for sterilizing, disintegrating, and discharging an aqueous sewage composition including human feces and includes an enclosed chamber having an inlet for the sewage composition at the top of the chamber, separate electrodes in the lower portion of the chamber, a standpipe having an inlet from the chamber and communicating with the upper portion of the chamber and discharging exteriorly of the chamber, and means for impressing a potential difference across the electrodes. The method is characterized by impressing a potential difference across the electrodes sufficient to effect electrolytic discharge of gas at at least one of the electrodes and impressing a current across the electrodes sufficient to cause ebullient roiling action in the composition to disintegrate the solid waste material and suspend the resulting particles in the roiling medium. This operation results in the formation of a solids-containing evolved head of lesser density above the aqueous sewage composition. The roiling action is continued whereby the head is continuously added to and expands for communication with and discharge through the standpipe.
Abstract:
The present invention relates in general to a new and improved process and apparatus for removing metallic ions from an electrolytic solution, and it relates more particularly to a process and apparatus which may be used to economically purify an electrolytic solution containing only minute amounts of metallic ions. Those knowledgable in the metal plating art will readily understand the application of this process and apparatus for the final treatment of metal finishing waste fluids. As is explained more fully hereinafter, the process and apparatus of the present invention is also effective in removing organic compounds and phosphates from the electrolytic solution under treatment.
Abstract:
Water treatment apparatus for use in aquariums and the like comprising the serial arrangement of spaced apart paralled disposed plates positioned in the water being treated. Consecutive plates are oppositely polarized at a relatively low voltage. The polarization of the plates is periodically or randomly reversed. The apparatus acts to kill bacteria, aerate and increase the circulation of the water thereby improving the general environment of the aquarium.
Abstract:
A device for supplying drinking water comprises a negative electrode chamber, a positive electrode chamber, and a porous partition for the chambers and through which cation particles are carried to the negative electrode chamber by the electroosmosis. By the supplying device, a water body including a plurality of cation particles is produced from a natural water body. The supplying device particularly includes an automatic control system with an actuating mechanisms adapted to cause the chambers to be supplied with the natural water and after the intermediary operations, to result in the production of alkalified water.
