Rejection of Perfluorochemicals (PFCs) by RO & NF Membranes: The Influence of PFC Chemistry, Membrane Type, Fouling & Feed Water Characteristics

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 strength or fouling conditions.
