Title : Treatment of resin effluent by electrochemical oxidation
Author Name : D.Prabhakaran, T.Kannadasan , C.Ahmed Basha
Synopsis :
Electro oxidation processes are developed throughout the world for ambient temperature destruction of organic wastes. Several of these processes are based on Mediated Electrochemical Oxidation (MEO). This article presents the experimental results of electro chemical study based on MEO process conducted for synthetic organic ion exchange resin materials. Investigation was carried out using the traditional noble metal oxide coated anode, RuO2/Ti and the mediators used for the experiment were in situ generated OCl- ion and the Fenton’s reagent (Fe2+/Fe3+ + H2O2),OHo.
The experiment was carried out in constant stirring batch reactor with current densities 1.25, 2.5, 3.75, 5.00 A/dm2 for various flow rates 20, 40, 60, 80, 100 L/H. The results of the experiments shows that the best effect of TOC reduction was found to occur at 3.75 A/dm2 in batch setup with flow rate of 20 L/H.
