CTA and TFC FO membranes treated produced water for up to three weeks. CTA outperformed TFC with higher water flux, lower RSF, and lower SRSF. Foulants were similar for both membranes, and TFC had higher fouling propensity. Weekly chemically enhanced osmotic backwashing minimally improve water flux. Membranes rejected over 90% of detected compounds, and TFC had higher rejection.
