| Popis: | Groundwater pollution has increased in recent years due to the intensification of agricultural and livestock activities. This results in a significant reduction in available freshwater resources. Here, we have studied the long term assessment of a green technology (1-4 L/day) based on a photobioreactor (PBR) containing immobilised microalgae-bacteria in polyurethane foam (PF) followed by a cork filter (CF) for removing nitrates, pesticides (atrazine and bromacil), and antibiotics (sulfamethoxazole and sulfacetamide) from groundwater. The prototype was moderately effective for removing nitrates (58%) at an HRT of 8 days, while its efficiency decreased at a HRT of 4 and 2 days ( The authors wish to thank the financial support of the European Union through the project LIFE18 ENV/ES/000199 and the Spanish Ministry of Science, Innovation and Universities through Project CTM2017-91355-EXP. Finally, European Commission (Erasmus program) and Government of Chile for supporting Lorenzo Rambaldo and Héctor Avila Cortés's visit at IDAEA-CSIC in Barcelona, Spain. |
