Presenter
Emily Briese (LinkedIn)
Emily is a fourth-year PhD student at Arizona State University in Environmental Engineering working with Dr. Paul Westerhoff. Ms. Briese is involved in the Nano-Enabled Water Treatment (NEWT) research center and the MEMCARE Superfund Research Center with Harvard. These research centers focus on removing heavy metals, like oxo-anions, from drinking water to reduce human exposure. Adsorption is a promising solution for contaminant removal as it is low-cost and can easily be implemented in Point-of-Use or full-scale systems.
In addition to her research, Ms. Briese is involved in leadership roles for each research center she is involved in. In NEWT, she holds a co-presidency in the Student and Postdoc Leadership Council and a position in the Student and Post-Doc Alumni Network within MEMCARE. After graduation, Ms. Briese is interested in a career in industry, designing and engineering solutions for water treatment challenges.
Presentation Synopsis:
Adsorbent Design for Arsenate and Vanadate Removal
As US EPA regulations become increasingly stringent, there is a need for adsorbent media screening and design for the selective removal of mixtures of oxo-anions. The primary focus of Emily’s research is to conduct predictive adsorption modeling for removing arsenate in the presence of competing species. This enables the evaluation of new and existing adsorbent material performance to exploit selectivity for varying water chemistries. In these predictive models, chemical equilibrium modeling through Surface Complexation Modeling (SCM) is used as an input to mass transport modeling through Pore Surface Diffusion Models (PSDM). This approach enables the predictive performance of various adsorbents in challenging water matrices to identify key variables in designing the next generation of adsorbents.
