Filtration of Gold Nanorods for Efficient Water Treatment System Design
Mentor: Dr. Ruth Baltus
Department: Chemistry and Biomolecular Engineering
Many pathogenic bacteria and viruses present in feed waters are non-spherical. Therefore, the design of efficient water treatment membrane systems for the removal of such particles requires an understanding of the impact of particle shape on particle rejection. Recent efforts in the Baltus lab have focused on developing a theoretical model of the rejection of capsule shaped particles from porous membranes. In this REU project, the student will carry out membrane filtration measurements using model particles as mimics of non-spherical organisms. The student will examine the impact of particle size, shape and filtration velocities on particle rejection from porous membranes. Experimental results will be compared to model predictions that have been developed by Dr. Baltus and her students.
