  • Patent number: 9340883
    Abstract: Exemplary electrolytic methods are disclosed relating to preparation of useful products, e.g., disinfectants, from aqueous solutions of electrolytes. Disinfectant production with a capacity of a single electrolyzer may amount to 1200 liters per hour and up to 600 grams of active chlorine per hour by utilizing 3-7 gram sodium chloride (NaCl) for the production of 1 gram of active chlorine on the basis of a reliable and safe hydraulic structure. A fresh water supply may initially be directed into an internal tubular cathode chamber for cathode cooling purposes, before the participation in final disinfectant production process. A coolable cathode may increase the hold-up time of the electrolyte in the electrode chamber without application of circulation circuits, improving significantly the efficiency of sodium chloride utilization. The simplicity of the method makes it possible to increase both the productivity of a single electrolyzer and the efficiency of the process.

Specifically, by using multiple anodes, each with different types of soluble metals, the system and method avoid the need for periodic plating bath replacement and also allow the ratio of metals within the deposited alloy to be selectively varied by applying different voltages to the different metals. The system and method further avoids the uneven current density and potential distribution and, thus, the non-uniform plating thicknesses exhibited by prior art methods by selectively varying the shape and placement of the anodes within the plating bath. Additionally, the system and method allows for fine tuning of the plating thickness by using electrically insulating selectively placed prescribed baffles.

    Abstract: A method of producing disinfectants by diaphragm electrolysis of an aqueous solution of sodium chloride is disclosed. Such disinfectants are used in agriculture, public health care and medical institutions, public water supply systems and elsewhere. A method for producing disinfectants is disclosed which permits adjustment of the range of the pH value from 2.5 to 8.5 by using devices with various capacities ranging from 1 to 600 g active chlorine per hour, while decreasing the consumption of electric energy and sodium chloride for the production of 1 g of active chlorine, and reducing the consumption of fresh water for producing of waste catholyte. The disclosed method processes the concentrated aqueous solution of sodium chloride in anode and cathode compartments at a lower flow rate, using the flow of fresh water through the inner space of a tubular cathode for cooling the solution.

  • Publication number: 20120152750
    Abstract: Disclosed are embodiments of an electroplating system and an associated electroplating method that allow for depositing of metal alloys with a uniform plate thickness and with the means to alter dynamically the alloy composition. Specifically, by using multiple anodes, each with different types of soluble metals, the system and method avoid the need for periodic plating bath replacement and also allow the ratio of metals within the deposited alloy to be selectively varied by applying different voltages to the different metals. The system and method further avoids the uneven current density and potential distribution and, thus, the non-uniform plating thicknesses exhibited by prior art methods by selectively varying the shape and placement of the anodes within the plating bath. Additionally, the system and method allows for fine tuning of the plating thickness by using electrically insulating selectively placed prescribed baffles.

  • Publication number: 20120061254
    Abstract: A method for obtaining a disinfectant from an aqueous solution of sodium chloride by using a diaphragm electrolyser is disclosed. The method comprise channeling a fresh water flow inside a tubular cathode, separating 0.4-0.8% of the quantity of the fresh water flow and channeling the separated fresh water flow into the cathode chamber. Next, 16-20% of sodium chloride at the concentration of 0.02-1.2% is channeled to the anode chamber after a sodium chloride mixer. Fresh water flow is channeled from inside the cathode to a branch of an anode chamber in a cover-mixer of an electrolyser. The flow, originating from the cathode chamber, is discharged for utilization, wherein an anolyte flow from the anode chamber is channeled to the branch of the anode chamber. The concentration of active chlorine in the anolyte is reduced by employing a water supply to a predetermined level required of a disinfectant and the disinfectant with a pH level of 5.5-7.5 is discharged from the electrolyser.
