This webinar is based on MPC project 597, Bacteria Removal from Stormwater Runoff Using Steel Byproduct Filters. This project addresses the fact that stormwater runoff is the one of the most common forms of non-point source pollution, which can degrade surface water quality. Fecal indicator bacteria such as Escherichia coli (E. coli) have been recognized as major contaminants that prevent the potable and non-potable reuse of stormwater runoff. This project aims at developing a low-cost media filtration technology using recycled steel byproducts to remove E. coli from stormwater. Recycled steel byproducts including steel chips and steel slag were evaluated in this study.
