Membrane Performance: Effect of Chlorine Treatment Published:
March 08, 2012 Abstract: Thin film composite (TFC) reverse
osmosis (RO) membranes play a significant role in addressing
rapidly expanding global needs for potable water. A well-known
problem of TFC membranes is their sensitivity to oxidizing
agents such as chlorine, which are used to disinfect the feed
water or remove fouling from the membrane surface. Many studies
on the chemical and performance degradation of these membranes
have been carried out, but the fundamental physical properties
of the functional polyamide barrier layer (PBL) and their
stability after chlorine treatment remain largely unknown. This
is mostly due to the lack of suita
