Reusing wastewater from oil‐related industries is becoming increasingly important, especially in water‐stressed oil‐producing countries. Before oily wastewater can be discharged or reused, it must be properly treated, e.g., by membrane‐based processes like ultrafiltration. A major issue of the applied membranes is their high fouling propensity. This paper reports on mitigating fouling inside ready‐to‐use ultrafiltration hollow‐fiber modules used in a polishing step in oil/water separation. For this purpose, in‐situ polyzwitterionic hydrogel coating was applied. The membrane performance was tested with oil nano‐emulsions using a mini‐plant system. The main factors influencing fouling were systematically investigated using statistical design of experiments.
