Why Traditional Carbon Anode is Not a Good Choice for Electrochemical Wastewater Treatment? Traditional carbon based anodes, such as graphite and glassy carbon, have the advantages of being a low-cost anode material. They can also be made with a large surface area, in the form of reticulated carbon or a packed bed. Their use is limited because carbon based anodes are known to be consumed during the electrolysis, which adds to the increase in the inter-electrode gap with a subsequent increase in solution resistance and a waste of

How Platinum Anode is Used for Electrochemical Wastewater Treatment? Platinum, widely used as an industrial catalyst, the platinum anode has been studied to use in electrochemical wastewater treatment to decompose bio-refractory compounds such as phenol, bisphenol-a, and wastewater from the tannery and textile industries. The main advantages of using the platinum metals include long service life and excellent catalysis towards certain reactions. However, its use is limited for a number of reasons. Foremost is the

What Anodes are Used for Electrochemical Wastewater Treatment? The selection of the anode material is probably the most important factor affecting the effectiveness of the electrochemical treatment of wastewater. The anode material can determine the current efficiency and overpotential, Inappropriate anode materials can cause problems of dissolution or passivation during operation. Many types of anodes are readily available for the oxidation of organic compounds including some surface modified composite materials. Certain anodes

What Anodes are Used for Electrocoagulation? Fe anode and Al anode are typically used for electro-coagulation processes, as their anodic dissolution products, Fe(OH)3 and Al(OH)3, can adsorb the suspended solids in the wastewater. The in situ generation of the coagulant has the advantages of simple equipment and less handling of chemicals. Moreover, since these coagulants have low solubility, so they can be easily removed from the treated water. Fe → Fe2+ + 2e-   Al → Al3+ + 2e-  The dissolution reaction
