Abstract

Abstract: 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. Abstract : Surface modification of hollow fiber membrane modules via in‐situ polyzwitterionic hydrogel coating to promote their antifouling propensity during water/oil separation is investigated. A systematic study employing the design of experiment approach was established to explore the impacts of main influencing parameters on the performance of surface‐modified vs standard pristine modules.
