Abstract

A portable device for the electrochemical processing of liquids which comprises a dielectric casing with cylindrical and coaxially aligned electrodes and an inter-electrode diaphragm partitioning the inter-electrode space into an anode and a cathode chamber, and current lead-ins. The cylindrical diaphragm made of ceramics on the basis of aluminum and zirconium oxides is installed coaxially to the electrodes. The electrodes and diaphragm are tightly fixed to make up an electrode-diaphragm unit whose anode and cathode chambers have elements for inputting and outputting liquids being processed, and the electrode-diaphragm unit itself is tightly fixed within the casing. The casing has ports in which hydraulic connector and an electric connector are tightly installed. Quick-disconnect hydraulic connections are connected on the casing's inner surface with the input and output elements of the electrode-diaphragm unit's anode and cathode chambers. The electric connecter is connected on the casing's inner surface with the current leads-in.
