Vegetation Filters (VFs) can be a sustainable solution to treat wastewater and to recover resources such as nutrients, water and biomass from small municipalities and isolated dwellings. However, under certain conditions, the leakage of nutrients, especially of nitrate, can represent a limitation. The latest published article of the SWQ group is entitled “Sustainable soil amendments to improve nature-based solutions for wastewater treatment and resource recovery”. It has been published in the Journal of Environmental Management. It assesses the treatment improvement through the addition of two amendments to the soil, woodchips and biochar, from the VF itself. A significant improvement in nitrate removal has been achieved when woodchips are amended to soil.
This research has been developed under the FILVER + Project framework. FILVER+ "Water reclamation by using a new concept of land application systems" (2017-2020) is funded by the State R&D&i Challenges Program of the Society of the Ministry of Economy, Industry and Competitiveness CTM2016-79211-C2-1-R (AEI/FEDER, UE). FILVER+ is coordinated by the researcher Dr. Irene de Bustamante Gutiérrez.
