Organic micropollutants are currently in the focus of those engaged in water research and management.
Small river systems in densely populated areas are particularly at risk. High wastewater loads and highly variable input patterns can exert considerable pressure on aquatic ecosystems.
Additional treatment methods at input pathways are required to reduce micropollutant loads in watercourses. Given the aim of finding the right measures to reduce micropollutants in watercourses the establishment of an emission and immission balancing is a precondition.
Retention soil filters (RSF) as a treatment technique is both low-cost and low in energy demand. Reduction capacities for individual organic micropollutants and especially the underlying physicochemical processes within the aerated soil filters have barely been studied up to now.
