<p>The present invention pertains to the field of water processing and more precisely to that of water purification using electrical power. This invention relates to a method for the electro-chemical treatment of aqueous solutions as well as to a device for realising the same. The present invention may be used for improving the cost-performance ratio of electrolysers and comprises simplifying their power supply systems and reducing the energy loss therein. The power supply device of the electrolysers comprises a capacitive power-dosing unit, a depolarising current circuit as well as an alternative current power supply. These elements are used for feeding DC pulses through the electrolysers and the constant component of the current is modified according to the formula Io = 4fC(UM - Uo / K), wherein f is the modification frequency in Hz of the current from the AC power supply, C is the capacitance of the capacitor in νF, UM is the amplitude value of the power supply voltage in V, Uo is the constant component of the voltage drop in the electrolyser in V and K is equal to 1, 2, etc. and represents the coefficient between the transmission and the voltage of the current pulse generator.</p> |
