Assessing Nutrient Removal in Stormwater Runoff for Urban Farming with Iron filings-based Green Environmental Media

Urban Farm DB summary

This study assessed the nutrient removal efficiencies of Iron Filings-based Green Environmental Media (IFGEM) for stormwater runoff, using an isotherm study, a column study of reaction kinetics, and microstructure examination. IFGEM, made from recycled materials like tire crumb and iron filings, demonstrated over 90% nitrate removal and 50-70% total phosphorus removal under most inlet conditions. The ammonia byproduct allows for potential reuse of spent IFGEM as soil amendments in urban farming applications.
