High Performance and Drawback of Pbo2 Anodes in Wastewater Treatment The development of PbO2 anodes for the oxidation of organics has gained great interest in recent years because of their good conductivity and large overpotential for oxygen evolution in acidic media, which enable the production of hydroxyl radicals during water discharge. PbO2 as itself has been used in the electrochemical treatment of wastewater and also in its doped form. On adding suitable dopant, PbO 2 exhibits exceptional electrochemical properties. Ni, Bi

Electrooxidation, Electrocoagulation, and Electro Fenton Method for Wastewater Treatment Electrooxidation (EO), electrocoagulation(EG) and electro-Fentonare(EF) are widely used electrochemical technologies. They are known as high efficiency, effective, eco-friendly, and cost-effective processes for the treatment of organic pollutants and it yields a very effective reduction result. What are the differences between these different electrochemical processes?   Electrooxidation In the electrooxidation process, pollutants

Boron-Doped Diamond (BDD) Electrodes For Wastewater Treatment Boron-doped diamond (BDD) electrodes have high O2 overpotential, make them better suited for the direct oxidation of contaminants than metal oxide anodes. The high activity of the BDD anode toward organics oxidation has been explained by the presence of weakly adsorbed •OH formed by water electrolysis at the anode surface. In addition to oxidizing organic contaminants, BDD anodes can generate ozone, H2O2, as well as ferrate. BDD can also produce peroxydicarbonate, p

Physical-chemical and Electrochemical Methods for Landfill Leachate Treatment Landfill leachate contains various contaminants (i.e. organic and inorganic pollutants), of which the composition and content vary with geographic location, waste composition, age, pH, moisture content, and other landfill site characteristics.  Leachate requires pretreatment on-site to meet standards to discharge to wastewater treatment plants or directly into surface water.    Due to the variable composition of landfill leachate, it conta
