Full Description

This powerpoint presentation begins by providing a brief overview of the project background, including: unintentional indirect potable reuse potential;pollution by emerging organic micropollutants PhACs, EDCs, and PCPs;adverse health/ecological consequences such ascancer,reproductive effects, and genital malformation; limitations of conventional watertreatment to eliminate micropollutants; compound specific retentionbehavior in nanofiltration/reverse osmosis (NF/RO) applications; and,retention behavior influenced bymodified membrane properties due to fouling. Four methodologies are presented, and results and discussion include: membrane characterization;impact of Jsub0/sub/k and recovery on rejection; rejection of PhACs/EDCs by clean NFmembranes; and,rejection of PhACs/EDCs by fouled NFmembranes. Includes tables, figures.
