John Chao, Ph.D.

Dr. Chao is a chemical engineer responsible for filtration R&D projects and large filtration system design. He works closely with sales and field engineers to identify filtration applications and configure desirable filtration processes for customized solutions. He designs lab apparatus for filter media testing to include all protocols to characterize parameters such as permeability, porosity, bubble point and surface properties.

Dr. Chao performed Post-Doctoral and Research at New Jersey Institute of Technology. Projects included characterization of ECTFE (Ethylene Chlorotrifluoroethylene) membrane which has excellent chemical resistance and very good insulation properties and is often used in the chemical and electrical industries. Dr. Chao established all protocols for tests performed, determining the porosity of the ECTFE membrane, studying the sorption behavior of the membrane in various solvents using Cahn C-31 microbalance. He worked with Nano-filtration apparatus to determine the permeate flux for pure solvents and permeate flux and the solute rejection of CMS-7 high flow membrane for solutions containing different dyes. Dr. Chao conducted research into pressure swing membrane absorption for pre-combustion CO2 capture from shifted Syngas (CO2/He). He developed numerical models using MATLAB to predict and validate the experimental pressure swing membrane absorption process results.

Dr. Chao received the North American Membrane Society (NAMS) Travel Award in 2013 and has more than 10 technical papers published and presented to professional organizations and conferences. He is affiliated with the American Institute of Chemical Engineers (AIChE) and North American Membrane Society (NAMS).

Dr. Chao earned a B.S. Chemical Engineering at the University of California-Berkeley, a M.S. Chemical Engineering at San Jose State University. Dr. Chao holds a Ph.D. Chemical Engineering from the New Jersey Institute of Technology.
