Batch and Column Studies for Removal of Sulphate from Real Wastewater Using Ion Exchange Resin

Abstract

In this study, sorption potential of anion exchange resin (Lewatit Monoplus M600) to remove sulphate from real wastewater was investigated. Kinetic studies were performed in batch experiments. A comparison of kinetic models applied to the sorption of sulphate onto resin was evaluated for the "infinite solution volume model" and "unreacted core model". Ratedetermining step is the liquid film control step of the unreacted core model. When pH values increased above 9, more than 80% sulphate removal was observed. Column sorption-elution experiments were performed for the removal of the sulphate from the wastewater by resin. The Thomas and the Yoon-Nelson models were applied to experimental data to determine the characteristic column parameters.
