Abstract:
In order to reduce the number of structural components, the size and the cost of an electrolyzed water producing apparatus, an electrolyzed water producing apparatus is equipped with a system in which the start and stop of the operation of an electrolyzer cell in the apparatus is controlled in accordance with the open/close operation of a water feed valve interposed in a raw water feed conduit for feeding raw water to the electrolyzer cell. An electrolyzed water producing apparatus comprises: an electrolyzer cell subdivided into an electrolyzing anode chamber and an electrolyzing cathode chamber with a partition membrane; a raw water feed conduit for feeding raw water from a water supply source to the electrolyzing chambers of the electrolyzer cell; a water feed valve interposed in the raw water feed conduit; a brine feed conduit connected to the raw water feed conduit; a brine feed pump interposed in the way of the brine feed conduit; a control means for start/stop controlling the operation of the electrolyzer cell in accordance with on/off condition of the water feed valve and for controlling the operation of the brine feed pump in order to regulate the concentration of water to be electrolyzed as fed to the electrolyzer cell; a diluting water feed conduit bifurcated from the raw water feed conduit at a point downstream of the water feed valve; and a communicating conduit connecting one of the electrolyzing chambers to the diluting water feed conduit for diluting electrolyzed water discharging from the one of the electrolyzing chambers with the raw water diverging from the raw water feed conduit and flowing through the diluting water feed conduit when the electrolyzer cell is in operation, wherein a percentage of the raw water diverging from the raw water feed conduit into the diluting water feed conduit is regulated to accordingly regulate a concentration of the diluted electrolyzed water to be taken out.
Abstract:
The softener is based on a capacitive-deionization (CDI) cell, in which the hardness ions are extracted, and disposed of still intact, in concentrated form. The softener is combined with a chelate to inhibit precipitation, in the appliance, from the concentrated effluent. The chelate being citric acid, the acidity is effective to keep the hardness ions in solution. The purify and regenerate modes of operation of the softener can be timed to coincide with the washing and rinsing cycles of the appliance, whereby the presence of the softener does not affect the speed and performance of the appliance.

Abstract:
A device and process are disclosed for the separate removal of oppositely charged ions from electrolyte solutions and recombining them to form new chemical compositions. The invention provides the ability to create multiple ion flow channels and then form new chemical compositions therefrom. The process is accomplished by selectively combining oppositely charged ions of choice from different electrolyte solutions via the capacitive behavior of high electrical capacity electrodes confined in insulated containers.
Abstract:
An electrolytic water treatment system improving upon the electrode life of electrolytic oxygen generators by reducing mineral precipitation and fouling that typically occurs in water treatment systems. The electrolytic water treatment system can include a softened water bypass stream into which a flow-through electrolytic element can be positioned. By eliminating exposure of the electrolytic element to hard water, scale formation on electrodes can be significantly reduced such that polarity reversal cycles of the electrolytic element decrease in frequency.

A system to prepare an antimicrobial solution by the electrolysis of brine is presented where the antimicrobial solution is a solution comprising HOCl that contains a HOCl concentration of 100 ppm or more at a pH of approximately 6.5. The system includes an electrolysis cell that is provided with a constant current by a digital DC power supply controlled by a microprocessor and a controlled brine concentration at a controlled rate, which can also be controlled by the microprocessor to deliver a fluid that is continuously observed by a pH probe and an ORP probe that provides input to the microprocessor to adjust voltage, pump rate and/or flow rate in a programmed manner by the microprocessor. A method to produce the antimicrobial solution, including a sporicidal solution, by the novel system is presented.

Abstract:
The present invention provides a method for automatically producing nano-gold/silver ionized water, the method including: a raw water supply step in which raw water is filtered by a filter F, passed through a flow control valve V for controlling the amount of raw water, and supplied after the amount of raw water is measured by a flow meter M in real time; a nano-gold/silver ionized water production step in which after the amount of the raw water is measured by the flow meter M, the raw water is passed through a nano-gold/silver ionized water producer P to produce nano-gold/silver ionized water; a control step in which a controller C connected to the nano-gold/silver ionized water producer P controls a microprocessor and a driver, which control the filter F and the flow meter M, a current/voltage driver, and the opening/closing of a valve; and a sensing step in which a sensor I connected to the controller C measures the amount and concentration of ionized water passing through the nano-gold/silver ionized water producer P to optimally supply the nano-gold/silver ionized water. Moreover, the present invention provides an apparatus for automatically producing nano-gold/silver ionized water having a simplified structure. Therefore, the apparatus can be easily fabricated with low cost. Since the ionized water is continuously produced using a waterway through which raw water flows, differently from the conventional techniques in which the raw water stays in a reservoir, it is possible to solve problems such as settlement of ionized water, and thus it is possible to produce nano-gold/silver ionized water having a desired concentration of gold/silver ions within a short period of time. As a result, the antibacterial and sterilizing activity which is an intrinsic property of the nano-gold/silver ions is improved, and the thus produced ionized water having strong detergency can be used as antibacterial and sterilizing water.
