Development of an EOR-produced petroleum wastewater treatment system through integrated polyacrylonitrile membrane and ZrO₂/sericin technologies: revelation of interactive mechanism based on synchrotron and XDLVO analyses.

ABSTRACT: Ultrafiltration technology is one of the most efficient methods to address the issues of enhanced oil recovery-produced petroleum wastewater (EOR-PW) treatment. However, membrane fouling significantly impairs the efficiency of PW treatment. Moreover, the impacts of the complex components (e.g., salt ions, heavy metal ions, and pH level) in PW on membrane performance and the underlying mechanisms (i.e., fouling modes and interactive force) need further exploration. Herin, a novel ZrO₂/sericin polyacrylonitrile (ZrSS) ultrafiltration membrane was developed for PW treatment, and the impacts and mechanisms of contaminants in PW on membrane filtration performance were systematically investigated using synchrotron-based technology and extended Derjaguin-Landau-Verwey-Overbeek (XDLVO)
