CEE 225: Physical and Chemical Separation Processes

Covers fundamental and applied concepts of physical and chemical processes related to engineered and natural environmental systems.  Topics include basic colloid chemistry and introduction to DLVO theory, coagulation and flocculation, sedimentation, mechanisms of particle removal in filters and transport in porous media, adsorption, disinfection, and control of disinfection by-products.

Faculty Biography

Sharon WalkerSharon Walker received her Ph.D. in Environmental Engineering, from the Department of Chemical Engineering at Yale University in 2004. She earned her M.S. in Chemical and Environmental Engineering from Yale in 2000 and two Bachelor of Science degrees from the University of Southern California in Environmental Engineering and Environmental Studies in 1998.  Dr. Walker and her students are investigating the factors controlling bacterial and nanoparticle fate and transport as it pertains to water quality. Specifically, the fundamental mechanisms involved in aggregation, deposition, and adhesion occurring at the molecular scale between environmental particles and surfaces are being explored. The fate of these biotic and abiotic particles to surfaces in groundwater and marine environments are actively being studied. These mechanisms also apply to particles interacting with other surfaces including membranes, filter media, and biomedical materials.
