In case of wastewater, the various pollutants become electrolytes and lower the electrical resistance in water. The electrolytes disassociate into cations, which move to the cathode, and anions, which travel to the anode, thus allowing continuous electrical flow in the water. An anion from the electrolyte will lose an electron and be oxidized when the electrolyte anion has less standard electrode potential than the hydroxide. A cation with a greater standard electrode potential than the hydrogen ion will also be reduced [More]

The Electro coagulation model comprised with Ericohrome Black T and oil/water emulsion where the primary mechanism operated were aluminum hydroxide precipitate and charge neutralization of developed model for wastewater pollution considering hydrodynamic conditions using chemical reaction of reagents and pollutants, where a multivariable modeling of anodes was described. The model combined a macroscopic/maximum gradient approach for all processes with pseudo equilibrium. [More]

Isotherm kinetics for arsenic removal from aqueous solutions by means of electrocoagulation through response surface methodology. It concluded that COD and Colour removal of 81.6% and 98.4%, respectively, were capable of treating bio-digester effluent within an electrocoagulator. [More]

Waste Water Treatment Electro coagulation & Electro Oxidation design optimized Cl ions, temperature in degrees Celsius, pH, intensity of current, time of electrolysis. From the results, the authors observed that current intensity, COD (chemical oxygen demand), TOC (total organic carbon), and electrochemical oxidation were major parameters [More]

In the Coagulation Reactor, when the cathode electrode makes contact with the wastewater, the metal is emitted into the apparatus. Then the particulates are neutralized by the formation of hydroxide complexes for the purpose of forming agglomerates. These agglomerates begin to form at the bottom of the tank and can be siphen out through filtration. [More]
