    Effects of Membrane Degradation due to Chlorine Exposure on the Removal of Neutral Organic Compounds by Reverse Osmosis for Potable Reuse by Carson Odell Lee (17810305)

    Published 2024
    “…Compounds that had an initial rejection between 50 and 95% had a rapid decrease in rejection during the first 230 ppm-h of chlorine exposure, whereas compounds with a new membrane rejection of >95% saw little change in rejection until chlorine exposure exceeded 2640 ppm-h. …”
