The most common problem ...

The most common problem behind chlorine damage of the membranes, is bio-fouling from allowing the membranes to sit idle too long (and/or not providing an auto-flush step with RO permeate at the end of the service run.)  The third common problem is running on hard water, and not providing effective anti-scalant/dispersant dose to the feed.  Another one behind that is poor engineering of the supply system coupled with attempting to produce more water than the design point by more than 20% above design (over-fluxes the lead membrane elements).
