Reducing The Fouling Of Microfiltration Membranes Through Uv-Initiated Surface Modifications Using Poly (Ethylene Glycol) Based Monomers, Christopher Lo, Matthew Truong

Materials Engineering

Meissner Filtration Product Inc. designs and manufactures membranes for food and beverage, microelectronics, ultrapure chemicals, and pharmaceutical industries. Membrane filters utilized in these industries have lifetimes greatly limited due to membrane fouling. Increasing membrane lifetime will reduce downtime, waste, and cost of operation. The proposed project is aimed to develop a methodology for synthesizing a fouling-resistant polymer coating layer on hydrophobic membrane surfaces for reducing membrane fouling and increasing membrane filterability (membrane lifetime) that are critical for effective membrane operations in the pharmaceutical industry. In this study, commercial membranes were coated with a solution containing a monomer, crosslinker, and photoinitiator …
