Research Article Nanofiltration/Reverse Osmosis as Pretreatment Technique for Water Reuse: Ultrafiltration Versus Tertiary Membrane Reactor The potential for nanofiltration (NF) and reverse osmosis (RO) in secondary effluent reclamation is noteworthy, but both processes require extensive pre-treatment to prevent membrane fouling and promote system longevity. In this study, performance of direct ultrafiltration (UF) and tertiary membrane bioreactors (tMBRs) as feed pretreatments were assessed on a pilot scale. Both technologies achieved high organic matter removal (87 and 93% for UF and tMBR, respectively). Differences in efficiencies were related to suspended biomass in the tMBR, which enhanced degradation of the dissolved organic substances (
