Ceramic Raschig Rings-Improving Removal of Organic Compounds from Landfill Leachate by Perozone (O3/H2O2)
For improving the treatment of landfill leachate by combination O 3 /H 2 O 2 , ceramic Raschig rings (CRR) with different surface areas were added to enhance mass transfer of ozone into liquid phase. To determine optimal conditions of reaction, pH and reaction time was also studied. The optimal pH r...
