Abstract:
This invention relates to an electrolytic ion water generator for producing alkali ion water containing alkali ions and acid ion water containing acid ions by introducing tap water or the like into an electrolytic cell comprising electrodes and ion exchange membranes arranged alternately which electrolyze the electrolytes in the water.Electrolytic cell unit panels having the same shape are constructed by attaching the electrode plate and ion exchange membrane onto each synthetic resin frame. The electrolytic cell unit panels are layered in a water-tight manner facing the front sides to front sides and the rear sides to rear sides via O-rings. A water-inlet external cover is attached at one end of the layered electrolytic cell unit panels, and a water-outlet external cover is attached at the other end of the layered electrolytic cell unit panels in a water-tight manner to secure the total assembly.Since the electrolytic ion water generator of this invention can be assembled just by layering electrolytic cell unit panels of the same shape, the assembly process is simplified and the whole device is compact. By adjusting the number of layered electrolytic cell unit panels, it is simple to manufacture a generator having the required ion water production capacity.When the flow-path switching mechanism which is actuated in response to the change of polarity of the electrode plate is installed within a separate panel inserted in the water-outlet external cover or between the water-outlet external cover and the electrolytic cell unit panel, the scale deposited on the cathode plate during operation can be removed without interrupting the generation of ion water.
Abstract:
A controlling apparatus which can control a continuous electrolytic ion water producing apparatus so that the electrolyzing capacity of an electrolytic cell is kept fixed against a variation of the flow rate or the quality of water upon passage of water to always achieve optimization and stabilization of electrolytic ion water produced. When water flows through the electrolytic cell, it is energized by a power source circuit to electrolyze the water to obtain electrolytic ion water. When a range change-over switch is manually operated, a dc voltage of the power source circuit is controlled in response to the range change-over switch by a control unit and a switching regulator to produce an electrolyzing voltage corresponding to the operated position of the range change-over switch. The water is thus electrolyzed with an electrolyzing strength of the electrolyzing voltage. During such electrolyzing operation, if the flow rate or the water temperature varies, then the pulse width of the switching regulator is corrected to automatically adjust the electrolyzing strength in accordance with the varying condition thereby to always keep the electrolyzing capacity of the electrolytic cell fixed.
Abstract:
An electrolytic ionized water producer of a continuous type is disclosed which does not require users to perform complicated operations and which makes it possible to obtain ionized water easily with a simple operation, to remove the fear of obtaining unnecessary ionized water in the case of reversing polarity and, further, to maintain a stable electrolyzing capability for a long time while removing scale in an optimum way in every water supplying operation. Specifically, the electrolytic ionized water producer is provided with a control circuit which operates at least a polarity reversing relay provided in a circuit for applying a DC voltage to a positive electrode and a negative electrode, detects water supply and zero flow water supply with a signal from a flow rate sensor and applies a DC voltage to the respective electrodes at a normal connection position when water is supplied to produce ionized water, sets a scale removing period of time corresponding to a water supplying period of time corresponding to integrated signals from the flow rate sensor, and applies a DC voltage to the respective electrodes at a reverse connection position only for a set period of time of scale removing operation in every water supplying operation.
Abstract:
A waste metal extraction apparatus is disclosed which includes a tank (1) having a plurality of oppositely disposed arcuate baffles (14) disposed on the sidewalls. The baffles are placed in an offsetting relation in order to direct the flow of a fluid through the cell in essentially a serpentine fashion. The arcuate baffles facilitate maintaining a maximum velocity through the turning radius of the fluid passing therethrough to prevent a solids buildup. In addition, the tank is placed at an angle of at least 6 degrees downwardly sloped ind the direction of flow. The tank bottom (6) includes a plurality of sockets (20) sized to engage a plurality of cathode supports (21) placed therein, with each support including a mating end (22) for mating with the socket. Each post includes a slot (23) extending substantially therethrough for accepting a cathode (13) therein. A conductive metal fork (31) is disposed over the post having legs (32) which extend the length of the cathode, providing uniform electrical properties across the surface of the cathode thereby providing for optimum, uniform metal removal. The tank further includes a sludge gate (36) at the outlet end thereof with the sludge gate provided for removing any solids which settle as the waste stream follows the serpetine path provided by the arcuate baffles, the sludge gate removing a concentrated solids-containing stream which may be filtered and recycled to the tank inlet. Utilizing the combination of flow modifying baffles, a sloped bottom and enhanced electrical contacting means provides for use of electrolytic cells for removing heavy metals from streams containing about 1-15% solids without requiring frequent down time for tank cleaning.
Abstract:
A device for regulating drinking water includes an electrolyzer divided into a negative electrode chamber and a positive electrode chamber by an unglazed partition, and electrodes disposed in the chambers and adapted to be energized by direct current for a prescribed period of time for separating water in the electrolyzer into two components having a hydroxyl radical in different densities, due to the electrolysis and electroendosmose. The negative electrode has a heating element disposed in a hollow space formed in the negative electrode to warm up the water body in the electrolyzer at each time of the electrolysis. A thermistor, or the like, is electrically connected to the heating element to control the temperature of the water body in the electrolyzer and to prevent overheating of the negative electrode.

An electrolytic water purification system operated from a battery includes an electrolytic cell which may purify water properly only when an applied voltage exceeds the battery output voltage. A power supply circuit energized by the battery furnishes the necessary higher voltage. An electrically driven pump is directly energized by the battery for pumping the water to be purified through the cell. The pump is automatically deenergized when the conductivity of the water or the available voltage is outside prescribed limits.

Abstract:
Apparatus and process for removing colloidal, oxygen demanding and odor causing organic materials, inorganic materials and other pollutants from waste water is provided. The initial pH and resistivity of the water is measured and adjusted to predetermined values. The color of the water is then measured and organic and inorganic materials are caused to precipitate from the water which is then subjected to a predetermined density of electrical current. The electrolysis coalesces colloidal materials which are removed mechanically and causes additional material precipitation, as well as acting to kill bacteria, viruses and other organic matter. Additional inorganic matter precipitation is induced and the water has a final pH, color and resistivity adjustment. An oxidizing agent is added to further reduce oxygen demanding and odor causing organic material and act on bacteria and other organic matter remaining. The water is then reusable or may be discharged into streams or sewer facilities.
