This powerpoint presentation begins by providing a brief overview of the growth of the nanofiltration (NF)/reverse osmosis (RO) industry. Several factors are presented that are impacting rejection: compound characteristics; membrane characteristics; and, system design characteristics. Predicting qualitative rejection categories is presented, along with a list of compounds detected in RO permeates inpilot-scale or full-scale testing; RO performance for single stage; RO performance impacted by staging; RO performance further impacted bybreaching of staged system; impact of chlorine damaged element onconductivity probing measurements; impact of breaching on compounddetection; hypothesized factors contributing towardcompound passage; and, knowledge gaps and industry needs. Includes tables, figures.
