Abstract Papastavrou H, Mantzavinos D, Diamadopoulos E:
"Advanced treatment of stabilized landfill leachate by coagulation, activated carbon adsorption and electrochemical oxidation",
In HazWasteManagement: C6.4, (Oct 2008)


Keywords    
Abstract   This work investigated the treatment of a landfill leachate that had previously undergone biological treatment. Coagulation with alum resulted in a 50% removal of COD. The optimum aluminum dose was 3 mM Al3+. Activated carbon adsorption of stabilized leachate that had been previously treated by coagulation resulted in an overall 80% removal of COD. However, a significant part of the organic matter (corresponding to 160 mg/L) was nonadsorbable. Electrochemical oxidation over boron-doped diamond electrode led to about 90% COD removal in 360 min with the resulting stream having a COD content of as low as 40 mg/L. Increase of current intensity from 15A to 21A did not increase the overall COD removal, yet it resulted in faster kinetics.
