Abstract
Phosphorus (P) losses from P-enriched agricultural land pose a long-term risk for the eutrophication of freshwaters. Current regulatory practices and mitigation measures to reduce P losses are considered insufficient to reduce P losses to biological threshold values in the foreseeable future. We propose a shift of paradigm and aim at developing filter technologies for trapping P in agricultural drainage discharge. The use of low-cost P sorbents, preferably recycled industrial products, in the construction of P filters, and the recycling of retained P to agricultural land makes the SUPREME approach sustainable and economically feasible. Optimizing filters for N removal by denitrification and exploring the filter functions for micropollutants further add to the benefits of applying filter technologies to drainage discharges. The interdisciplinary project comprises seven work packages: (i) High affinity sorption to industrial sorbents, nanocomposites and retention by precipitation techniques, (ii) hydro-kinetic P retention, filter substrate stability and life-time, (iii) development and exploration of four drainage filter technologies at field scale, (iv) N-removal by denitrification, (v) risk assessments of filters and function towards micro pollutants, and recycling of P-saturated filters, (vi) modelling of filter function and scenario analysis, and (vii) analysis of the cost-effectiveness of the filter technologies and strategies for filter implementation at the catchment scale. The SUPREME approach relies on a public-private partnership with more than ? participating industries. A strong collaboration with five international universities ensures scientific knowledge transfer, which is also strengthened by five PhD projects and one post doc. The project addresses an urgent requirement by environmental planners and land users by providing solutions for reconciling intensive agricultural production with European water quality goals.
