Graphene oxide redistributes fouling towards its recoverable fraction in a bio-based Jatropha polyurethane microfiltration membrane

Replicate-level data, vendor-native instrument exports and analysis code for a comparison of two flat-sheet microfiltration membranes cast from a Jatropha-oil polyurethane: one unmodified (JPU) and one carrying 0.5 wt% graphene oxide (JPU/GO). The membranes were run in cross-flow on four feeds - lake water, municipal wastewater, palm oil mill effluent and food-waste leachate - under two independent operating-point normalisations, one holding relative load constant at 0.93 of each membrane's own critical flux and one holding absolute flux constant at 232.5 LMH. Critical flux was measured separately on every feed.
