Abstract/Contents

Abstract: We are advancing technologies that capture, treat, and recharge stormwater for groundwater replenishment and storage. Urban stormwater can be a significant source of pollutants, including nutrients, organic compounds, and pathogens. Work is ongoing to develop a novel treatment system for nutrient removal that includes iron filings to remove phosphorus and a woodchips to biologically degrade nitrate. These bioreactors host an endemic population of white rot fungi (WRF) that can also be harnessed to remove organic pollutants, pathogens, and to provide a multipurpose stormwater treatment technology. !
Previous laboratory studies show that up-flow woodchip bioreactors degrade nitrate. Current work focuses on optimizing nitrate removal by creating an advection-dispersion model, determining an algorithm for real-time control of denitrification based on external temperature, and augmenting woodchip bioreactors with biochar to control dissolved organic carbon (DOC) leaching. This project also examines the potential for amending woodchip bioreactors with WRF to enhance removal of organic pollutants present in stormwater.
