Black carbon amended engineered media filters for improved treatment of dissolved trace organic contaminants in stormwaterr runoff
Abstract/Contents
- Abstract
- Urban stormwater runoff threatens human and aquatic health by transporting anthropogenic pollutants into receiving water bodies. Recent attention has focused on opportunities for beneficial use of stormwater runoff. Most significantly, cities in drought-stressed regions are planning to incorporate stormwater runoff into their drinking water supply portfolios through capture and managed aquifer recharge. Improved stormwater treatment, specifically for harder-to-remove and potentially-toxic dissolved trace organic contaminants (TrOCs), is necessary to realize beneficial use of stormwater runoff and protect human and aquatic health. This dissertation focuses on understanding the performance and limitations of black carbon (BC) amended engineered media filters for improved stormwater treatment. Long-term column experiments with high-flow rates and contaminant transport modeling are used to elucidate the kinetic limitations of TrOCs removal for a high-temperature gasification biochar and regenerated activated carbon and push the boundaries of what is possible for stormwater treatment. Results from this work are used in the development of a design tool that incorporates long-term filter performance modeling into stormwater management design and sizing processes.
