Abstract:
A high-purity water producing equipment comprises a primary purification treatment system, a primary deionized water tank, a secondary purification treatment system for producing high-purity water from a primary deionized water, a circulatory system pipe for returning the produced high-purity water to a primary deionized water tank and a branch water feed system branched off from the circulatory system for feeding the high-purity water to a use point. An electrolytic unit for producing the anolyte EIW (electrolytic ionized water) to be catholyte EIW from the electrolysis of the high-purity water is provided as a bypass midway along the circulatory system. The anolyte EIW is added to the circulatory pipe downstream of the branching point toward the use point, when cleaning of units is necessary.
Abstract:
A bone lengthening mechanism is placed into a bone which is then lengthened by extending the mechanism. The mechanism is extended by effecting a rotational movement in a drive bolt which mates with a threaded portion in a section of the mechanism. The threads convert the rotational movement to a longitudinal force thereby lengthening the bone.

Abstract:
A halogen generator produces a halogen sanitizing agent to sanitize water in a spa or other water feature. A coaxial wall fitting desirably couples the halogen generator to the water feature. The halogen generator desirably includes a bipolar electrolytic cell in which a center electrode plate rotates between stationary anode and cathode plates. The bipolar electrode includes a plurality of vanes which motivate water flow between the anode and the cathode. The vanes on the rotating electrode also produce a flow of water through the generator. In this manner, the bipolar electrode functions as a impeller to pump water through the halogen generator. The vanes are positioned between the electrode and cathode, and are sufficiently spaced from the cathode to inhibit scale formation on the cathode. The vanes, however, generally do not contact the cathode when rotating. The rotational direction of the electrode relative to the cathode may be reversed periodically and/or the gap spacing between electrode and the cathode may be decreased periodically to enhance removal of scale.
Abstract:
An apparatus for electrochemical purification of water and for regulation of acid-alkaline properties, Red-Ox characteristics and catalytic activity of water that can be used for obtaining washing and disinfecting solutions. The apparatus includes at least one electrochemical cell which contain vertical coaxial cylindrical and rod electrodes made from material nonsoluble during electrolysis and an ultrafiltration ceramic diaphragm installed in the bushings between the electrodes to create inter-electrode space in the electrode chambers. The lower and upper bushings have a channels for the treated solution supply into and discharge from the electrode chambers. The channels are connected to the feeding and discharging adjustment lines. There is also a metering pump on the water line for sodium chloride dosing into the water to be treated. The water line contains a flow regulator connected to the feeding and discharging adjustment lines. Poles of the power supply are connected to the electrodes. The feeding line is connected to the inlet of the negative electrode chamber and the output of the negative electrode chamber is connected to the inlet of the positive electrode chamber by a special line which has an adjustment for discharging a part of the degasified treated solution from the chamber of the negative electrode. A catalyst chamber can be installed on the special line. The catalyst chamber contains a mixture of particles of carbon and manganese dioxide. A separator with a tangential inlet is used for discharging a part of the degasified processed solution.
Abstract:
An apparatus for destroying bacterial pathogens including at least one pair of electrodes secured in a housing configured to constrain flow of water through the region between the electrodes. In one construction, the electrodes are supported in a tube with sides of each member of an electrode pair conforming to the inner surface of the tube and electrode surfaces form a slotted space through which the water passes. The electrodes and space between the electrodes are also subject to a magnetic field which reduces rate of deposition of calacerous deposits on the electrode surfaces thereby extending the period of time between required cleaning of the electrodes. The electrodes can be simple slabs or screens or both. The electrodes are preferably tin, titanium, brass, iron or stainless steel.
Abstract:
The present invention is directed to an apparatus for electrolyzing water. The electrolyzing apparatus includes a rectangular parallelpiped shaped casing having first and second chambers through which water flows. An inlet port at the first chamber conducts water into the first chamber from outside of the apparatus. Separate first and second outlet ports at the second chamber conduct the water to outside the apparatus from the second chamber. The first and second chambers are partioned by a wall. A communication path through the wall provides communication from the first chamber to the second chamber. Anode and cathode plates are disposed within the second chamber to generate a potential difference therebetween, so that the water which flows through the second chamber is electrolyzed. The communication path includes a fluid friction generating device, such as a plurality of circular holes having various diameters which are aligned along a line perpendicular the direction of the water flow. When the water passes through the circular holes, the fluid friction is generated along this line, so that the distribution of flow speed of the water in the second chamber becomes substantially uniform with respect to this line.
Abstract:
A zebra mussel control device uses a combination of electrical current and air bubbles to kill or disable mussels entering water intakes. The current is fed between electrodes that extend radially at equiangular positions around a cylindrical inlet of the water intake. Bubbles are created by an annular air chamber of the water intake below the cylindrical inlet. The bubbles rise, and pass through the gaps separating adjacent electrodes. Mussels entering the gaps are moved upwardly in the gaps by the action of the bubbles, thus increasing the normal transit time of the mussels through the gaps. In the result, the mussels are subjected to electrical current for a longer time than would be the case without the bubbles, and are disabled for a time sufficient to ensure that they pass through the water intake without attaching. The bubbles also drag any drifting mussels away from the water intake. This arrangement has been shown to be a very effective way to control zebra mussel blockage of water intakes.

An apparatus for producing electrolyzed water comprising an electrolytic cell, wherein the electrolytic cell includes an anode plate having a through-hole, a cathode plate having a through-hole and a sealing member. The electrolytic cell is constructed of the anode plate, the cathode plate, and the sealing member with the sealing member interposed between the anode plate and the cathode plate. Thereby a electrolytic chamber for electrolyzing subject water to be electrolyzed is defined between the anode plate and the cathode plate. One of the through-holes of the anode plate and the cathode plate serves as an inlet for introducing the subject water into the electrolytic chamber, the other through-hole serves as an outlet for discharging the subject water into the electrolytic chamber.
