An electrodic support structure for coaxial electrolytic cells suitable for operating in both monopolar and bipolar configuration is provided. The electrode support structure has a support plane made of an isolating material provided with a plurality of housing seats suitable for housing a plurality of electrodes arranged homothetically to each other, and a partition member made of insulating material, provided with a plurality of electrode positioning means, integral with or mechanically connected to the support plane and arranged orthogonally thereto.

Electrodic support structure for coaxial electrolytic cells

The invention relates to an electrode suitable for decreasing the chemical oxygen demand of waste-water comprising: a) a permanent component; and b) a sacrificial component arranged face-to-face and releasably attached to the permanent component and in electrical contact therewith, said permanent component consisting of a Substrate of a valve metal equipped with a catalytic coating containing noble metals or oxides thereof, said sacrificial component containing elemental iron. Further the invention relates to a method for abatement of the chemical oxygen demand in an aqueous waste containing oily compounds, glycols or waxes, optionally consisting of a foundry waste, by an electrolytic process involving anodic chlorine evolution in the presence of trivalent iron. Chlorine evolution may be carried out on the surface of an anode consisting of a catalytically activated-valve metal permanent component coupled to an iron-containing sacrificial component.

Electrode for electrochemical abatement of chemical oxygen demand of industrial wastes

The invention relates to an electrochemical device which simultaneously carries out the production of an oxidising solution at controlled composition containing hypochlorous acid and the sprinkling thereof in a continuous process, useful for biocide treatments in agricultural fields. The device can be installed on motor vehicles or mobile means in general.

Electrochemical device for biocide treatment in agricultural applications

There is disclosed a treatment process of wastes containing organic molecules with electron-withdrawing groups on conjugated unsaturated bonds, for instance belonging to aromatic rings. The process comprises an electrochemical reduction step and a simultaneous or subsequent oxidation step, optionally also of electrochemical nature.

Method for treating industrial waste waters

A bipolar electrolytic cell particularly useful for electrochemical processes carried out with periodic reversal of polarity is provided. The cell is equipped with a series of concentric electrode pairs, the innermost pair and the outermost pair being connected to the poles of a DC generator and the intermediate pairs acting as bipolar electrodes. The different pairs of electrodes are arranged and connected in such a way that, at each stage of the process, the overall cathodic area is equal to the anodic area.
