dc.description.abstractAutochthonous carbon fxation by algae and subsequent deposition of particulate organic matter can have signifcant efects on redox conditions and elimination of trace organic chemicals (TOrCs) in managed aquifer recharge (MAR). This study investigated the impacts of diferent algae loadings (0-160 g/m2) and infltration rates (0.06-0.37 m/d) on overall oxygen consumption and elimination of selected TOrCs (diclofenac, formylaminoantipyrine, gabapentin, and sulfamethoxazole) in adapted laboratory sand columns. An infltration rate of 0.37 m/d in conjunction with an algae load of 80 g/m2 (dry weight) sustained oxic conditions in the sand bed and did not afect the degradation of TOrCs. Thus, the availability of easily degradable organic carbon from algae did not infuence the removal of TOrCs at an infuent concentration of 1 Ìg/L. In contrast, a lower infltration rate of 0.20 m/d in combination with a higher algae loading of 160 g/m2 caused anoxic conditions for 30 days and signifcantly impeded the degradation of formylaminoantipyrine, gabapentin, sulfamethoxazole, and diclofenac. Especially the elimination of gabapentin did not fully recover within 130 days after pulsed algae deposition. Hence, measures like micro-sieving or nutrient control are required at bank fltration or soil aquifer treatment sites with low infltration rates. © The Author(s) 2023en
