  • Osmotic versus conventional membrane

    2017-2-1 · The high quality FO permeate would alleviate membrane fouling in the downstream RO process, which is a major issue for cost-effective application of conventional OMBR-RO for water reuse (Farias et al., 2014, Al Ashhab et al., 2014). Thus, additional cost saving for OMBR-RO can potentially be derived from a more stable water production from the downstream RO unit with less frequent cleaning and longer service time in comparison with conventional MBR-RO.
