OMPs degradation in riverbank filtration systems
In this study we employ metagenomics to advance the understanding of microbial processes responsible for the removal of OMPs during riverbank filtration. Metagenomics enables comprehensive, culture-independent analysis of microbial communities by directly sequencing the total DNA present in environmental samples. This method allows for in-depth characterization of both taxonomic composition and potential functions, thereby offering unique insights into the metabolic pathways and ecological interactions that may contribute to the degradation or transformation of OMPs in sediment and soil environments. This information is crucial not only for identifying key microbial taxa and degradation pathways but also for developing mechanistic models of OMPs attenuation that combine microbial activity information with hydrogeochemical conditions. Ultimately, the integration of metagenomic data into the study of RBF systems will significantly enhance our mechanistic understanding and help optimize design and operation for micropollutant removal in wastewater-impacted settings. This study aims to (i) provide a comprehensive overview of the potential for RBF systems to remove OMPs from WWTP effluent, (ii) identify key knowledge gaps in the mechanistic understanding of RBF processes, and (iii) propose experimental frameworks to distinguish the contributions of sediment and soil microbial communities to the removal of OMPs. By addressing these objectives, this research seeks to establish a foundation for the development of sustainable, nature-based solutions for OMPs management in treated wastewater.
