  4. DESIGN AND OPERATION PRINCIPLE

  The main part of the plant is an electrochemical reactor that comprises a battery of electrolytic elements PEM-3 connected hydraulically in a parallel-series manner, each of the elements being an independent flow-through electrochemical reactor. The reactor battery is compactly accommodated in the plant body together with the current converter. A water-jet pump that serves as a salt solution metering device is built into the hydraulic system of the plant.

  The reactor battery is powered by a stabilized current converter. The converter is a pulsed high-frequency rectifier equipped with a monitoring ammeter "A" and a voltmeter "V" located on the front panel of the plant. The body of the plant accommodates "CATHOLYTE" valve for controlling catholyte flow rate and "SOLUTION" for controlling the amount of salt solution fed to the plant. The current rectifier is turned on automatically by water flow through the plant.

  The operating principle of the plant consists in electrochemical synthesis of activated solutions (catholyte and anolyte), respectively, in the cathode and anode chambers of electrolytic element PEM-3 from salted water. During flowing, every micro-volume of water contacts the electrode surface. As a result, non-equilibrium change in water structure takes place, and water is enriched with electrochemical reaction products.

  5. SAFETY MEASURES

  Operation and repair of the plant must be carried out in compliance with the present certificate and the safety rules.

  During operation, to avoid the plant failure, the following is prohibited:
  • to perform maintenance of the electrochemical battery when the plant is connected to the electric mains;
  • to feed water with mechanical impurities through the plant;
  • to turn on the plant if the inlet water temperature exceeds 35°Ñ;
  • to store and transport the plant with remaining water at temperatures lower than 0°Ñ;
  6. PRE-STARTING PROCEDURE

  Install the plant in a ventilated room equipped with combined extract and input ventilation, in the immediate vicinity of a tap of a pressure water supply line, a drain to the sewerage system and an electric outlet.

  Connect the plant to the water tap by means of the sectional muzzle and direct the hoses marked, respectively, "ANOLYTE" and "CATHOLYTE" to the sink for draining. (To fit the sectional muzzle to the smooth outlet of domestically manufactured tap, proceed as follows: slip a serrated fastening nut on the tap, than slip on a rubber sealing bush, its cone upwards, or a rubber sealing ring; after that screw the adaptor bush and the nut together to a stop. For a tap outlet with inside thread, the muzzle with a threaded adaptor bush and two sealing washers is used. If the tap has outside thread, the muzzle is mounted without a threaded adaptor bush, with one sealing washer).

  Immerse the end of the hose having a filter and marked "SOLUTION" on the plant body into a tank with prepared solution of sodium chloride (kitchen salt) in tap water. Set the knob of the "SOLUTION" valve to "SHUT" position (clockwise).

  Connect the plant to the electric outlet.

  7. OPERATING PROCEDURE

  By means of the cock of the pressure water supply line and the valve "CATHOLYTE", adjust the hydraulic operating mode of the plant (set the required volumetric flow rate from "ANOLYTE" and "CATHOLYTE" hoses) in accordance with Appendix 1, which is a process mode chart of the plant. (Filling of a 250 ml measuring vessel during 22 s from "ANOLYTE" hose will correspond to the plant output of 41 l/h in terms of anolyte. See Table 1).

  Turning-on of the current converter is checked visually by the presence of voltage across the reactors as indicated by the voltmeter "V".

  By rotating the knob of the "SOLUTION" valve counterclockwise, feed sodium chloride solution to the plant in an amount required for setting a maximum current as indicated by the ammeter "À" (8-10À.). Adjusting the amount of sodium chloride supplied to the plant by means of the knob of the "SOLUTION" valve, set the voltage as indicated by the voltmeter "V" in accordance with the operating mode selected on the basis of the process mode chart of the plant (Appendix 1).

  After the plant has reached steady-state operation, direct the hose marked "ANOLYTE" (Anolyte out) to the plastic container for anolyte collection.

  On completion of the plant operation, disconnect it from the electric mains, open the valves "CATHOLYTE" and "SOLUTION". Take out the hose with the filter at its end from the tank with sodium chloride and put it in a tank containing water. Flush the plant with tap water during 2-3 minutes.

  8. MAINTENANCE

  After every 10-12 hours (in total) of operation, routine maintenance must be carried out including reactor washing with acid solution in order to remove cathode deposits on electrodes.

  The washing procedure is as follows:
  • disconnect the plant from the electric mains;
  • stop water supply to the plant from the pressure water supply line;
  • set the knob of the "Solution" valve to "Shut" position, and the knob of the "Catholyte" valve to "Open" position;
  • prepare 1-1.5 litre of 10% solution of hydrochloric acid (HCl) in a standard plastic container (bottle);
  • screw the adaptor bush (3) assembled with the blower (4) on the plastic container (5) with acid solution;
  • screw the adaptor with the hose from the connection of the "Water" inlet line (inlet) on the bush;
  • place anolyte and catholyte outlet hoses in an empty plastic container;
  • by compressing the air blower (4), provide feeding of acid solution through the electrochemical reactor to the empty plastic container; the characteristic reaction with foaming of the outgoing acid solution and gas release indicates the normal course of the washing process. Precautions against splashing of acid solution must be taken.
  • leave acid solution in the reactor for 15-20 min.;
  • if necessary, repeat the washing operation; to do this, place the adaptor bush of the inlet line on the plastic bottle containing pumped acid solution;
  • on completion of washing, connect the inlet of the plant to the tap of the pressure water supply line, flush the plant reactor with water to remove remaining acid, bring the plant to the condition corresponding to the operating mode.
