ABSTRACT |
This study was conducted to evaluate the removal efficiencies of organic matter and pharmaceuticals and to identify the removal mechanism of pharmaceuticals using sand obtained from Hwangryong River in Jangsung. Batch and column studies were used to simulate managed aquifer recharge (MAR) systems. All experiments were performed using field effluent containing pharmaceuticals from Damyang Wastewater Treatment Plant as an influent. Based on the removal results of organic matter and pharmaceuticals from the batch and column experiments, soil organic matter (SOM) and microbial activity were found to effectively remove target contaminants. The removal of organic matter was found to increase under biotic conditions. Neutral and cation pharmaceuticals (iopromide, estrone, and trimethoprim) exhibited removal efficiencies higher than 70% from natural sand and baked sand media in batch and column studies. Carbamazepine persisted in the sand batch and column studies. Anion pharmaceuticals (ketoprofen, ibuprofen, and diclofenac) can be removed under conditions featuring high SOM and adenosine triphosphate (ATP) concentrations in the sand surface. Based on the experimental Batch and column results, biodegradation and sorption were found to be important mechanisms for the removal of pharmaceuticals within the simulated MAR systems. |
