91³Ô¹ÏÍø civil engineering undergraduates have worked with Dr. Shimabuku on developing biochar, a low-cost and sustainable alternative to activated carbon, to use in drinking water filters to remove per/poly-fluorinated alkyl substances (PFAS) often referred to as “Forever Chemicals”.
A goal of the project was to determine how biochar production conditions, like peak temperature and heating duration, would influence the performance of biochar.
A comparison of how biochar is produced by a manufacturer based out of Spokane County versus at the 91³Ô¹ÏÍø lab is shown. Students that visited this facility learned what the range of production conditions this biochar manufacturer can achieve, which was used to inform the production conditions they tested in the lab.
Working with Dr. Shimabuku, 91³Ô¹ÏÍø undergraduates are also studying the effects of wildfires on drinking water as part of a 5-year USDA Forest Service Grant. Students are working to treat drinking water sources impacted by a wildfire with activated carbon that could remove organic contaminants. The test is being performed with a jar test apparatus that can precisely simulate mixing conditions achieved in full-scale drinking water treatment plants.
Undergraduates in the Environmental Engineering lab have had the opportunity to solve real-world environmental engineering problems. In addition to awards mentioned, four 91³Ô¹ÏÍø undergraduates have been co-authors on a peer-reviewed publication with Dr. Shimabuku.
