Director – Technical Services and R&D, Complete Filtration Resources (CFR)
Saagar Vijayaragavan is the Director of Technical Service and R&D at Complete Filtration Resources (CFR). He earned his PhD in Chemical Engineering from Michigan Technological University. Saagar’s doctoral work focused on viral protein purification using chromatography, functionalized membranes and solvent extraction techniques. Saagar also completed a Post-Doctoral Associate from South Dakota State University (SDSU). At SDSU, he worked in the state of the art dairy science facility performing industrial and application oriented research. At CFR, Saagar is a vital member of the technical team focusing on technical support, system optimization, designing and pilot research.
Dairy membrane industry offers a wide selection of membranes in low and high pressure operations. The polymer chemistry, configuration and construction are chosen to meet MWCO, minimize fouling, maximize area and flux. However, with new and expanding dairy ingredient portfolio, there appears to be a need for process engineers to broaden their horizon and laterally think of membrane selection and its accompanying operations. There is a need to understand and revisit flux-rejection concepts based on engineering variables (hydraulics, pressure, mechanical etc) and physicochemical properties (size, charge, interaction, solubility, temp etc). The goal of this presentation is to use examples and provide a lateral approach into membrane selection and relevant operating variables from an engineer’s point of view.
