The paper describes thesis research that elucidates the permeation mechanism of trace organics through Reverse Osmosis and Nanofiltration membranes. Specifically, the effects of size, charge and solute-membrane affinity on rejection (both time-variant and steady state) are investigated under varying feed conditions such as changing pH, ionic streng...

Fouling has always been an issue in all membrane systems, and it is more problematic when concentration polarization (CP) is high.This research investigates how patterns can affect CP layer in a reverse osmosis (RO) or nanofiltration (NF) system by evaluating the effects of velocity, pressure drop, concentration distribution and shear stress on the...

This work is at the interface of research and practice, which is ideal for the Membrane Technology Conference. We take our academic understanding of membranes and computer modeling techniques and show how it can enhance the process engineering work being done by those in the field....
