Low fouling membranes have been touted as a solution to the reduction in
performance that is often observed in membrane processes. A recent
investigation conducted by Alexander et al., however, found that a number of
membranes characterized as "low-fouling" actually had higher fouling
propensities than other standard membranes. Nevertheless, the authors could
only speculate as to why these membranes performed at these levels. To this
end, the study examines the surface characteristics of a low-fouling membrane
and compares them to those of a standard reverse osmosis (RO) membrane. The performance of
both membranes is characterized using hydrophilic and hydrophobic colloids and
discussed in terms of their surface chemistries to determine the mechanisms by
which low-fouling membranes may become fouled.
