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. Hydrogen is channeled to an exhaust outlet from the cathode chamber. An electrolyser for use with the method is also disclosed. |
