The article presents a comparative analysis of chemical substances which are formed in natural waters with different concentrations of humic and fulvic acids under the influence of ozone and chlorine, as a result of electrochemical processing. The authors present thermodynamic evaluation of the probability of the formation of transformation products under the influence of oxidizing reagents and during anode oxidation, and demonstrate the effectiveness of electrochemical purification of natural waters from humic compounds by cathode activated carbon. The scheme of a device to perform this process has been developed.
