Sammendrag
Mitigation of antibiotic resistance genes (ARGs) emissions has become a high priority and technologies able to effectively decrease their release to the environment are needed. Membrane filtration, in particular nanofiltration (NF) or reverse osmosis (RO) may be an effective technology. The study focused on mitigation of antibiotic resistance genes (ARGs) emissions to aquatic environment and the aim was to understand whether and to what extent ARGs can be removed by different membrane filtration processes. The specific objective was to assess the removal rate of the ARGs from ultrapure water and wastewater treatment plant (WWTP) effluent during experiments with ultrafiltration (UF), nanofiltration (NF) and reverse osmosis (RO) membranes. In addition, the potential of UV-LED at 265 nm for the treatment of the ARG-rich membrane concentrate was assessed.
