Electrochemical Treatment

Any chemical reaction that involves the transfer of electrons between two substances—usually a liquid and a solid—and is either triggered by or accompanied by the flow of an electric current. An oxidation-reduction (redox) reaction drives the movement of electrons in an electrochemical reaction from one chemical compound to another. When electrons are moved from one substance that is being reduced to another that is being oxidised, a redox reaction takes place. The anode and cathode, the two conducting electrodes of electrochemical cells, are used. The electrode at which oxidation takes place is known as the anode. Reduction happens at the cathode electrode. One or more advantages like - Materials that are affordable and non-toxic. And the drawbacks are like:

Lack of recycling and potential leakage are (weak acid electrolyte reacts with zinc) limited timeframe inconsistent voltage.
