It has been established that the preliminary electrochemical decontamination of water significantly reduces the microbiological contamination of polypropylene and coal filtration elements. It has been shown that the previous electrochemical activation normalizes the pH and redox potential, reduces the mineralization of water, its turbidity and color. A significant increase in the number of hydrophilic pores on the surface of activated carbon as a result of its interaction with activated aqueous solutions was established. The characteristic changes of the impedance hodograph in the low-frequency region that characterize the degree of filter contamination were revealed. Characteristic changes of the hodograph in the low-frequency region are revealed which characterize the degree of filter contamination. A structural scheme of a filtration unit with a module of electrochemical disinfection, frequency sensors of pollution and a microprocessor control system was proposed.
