Abstract


  • This study investigated the performance of the forward osmosis (FO) process for treating

    produced water. Water permeate flux and reverse salt flux (RSF) were examined at different feed

    pH values and operating configurations (i.e. FO, pressure retarded osmosis (PRO), and reverse

    osmosis (RO) modes). Acetic acid was selected as a model organic acid to present the dissolved

    organic fraction in produced water. Results reported here indicate that only membranes specifically

    designed for FO applications can be used in the FO and PRO modes. Due to the internal

    concentration polarization phenomenon, the PRO mode resulted in a higher water permeate flux

    and RSF than those in the FO mode. Acetate rejection was pH dependent in both the FO and RO

    modes. Furthermore, in the RO mode, acetate rejections by the FO membranes were higher than

    their nanofiltration counterparts. Results reported here suggest that FO can be a viable treatment

    option for the removal of dissolved organics from produced water.
