%X This study develops electrospun nylon 6,6 nanofiber membrane (NFM), incorporating zeolitic imidazolate framework-8 (ZIF-8) as the additive for produced water (PW) filtration. Electrospun NFM is suitable to be used as a filter, especially for water treatment, since it has a huge surface area to volume ratio, high porosity, and great permeability compared to the conventional membranes. These properties also enhance its competitiveness to be used as reverse osmosis pre-treatment, as the final stage of PW treatment water reuse purpose. However, the fouling issue and low mechanical strength of NFM reduces hydraulic performance over time. Therefore, this study employs ZIF-8 as an additive to improve nylon 6,6 NFM properties to reduce fouling and increase membrane tensile strength. Results show that the optimum loading of ZIF-8 was at 0.2. This loading gives the highest oil rejection (89), highest steady-state pure water permeability (1967 L/(m2·h·bar)), 2� higher than untreated nylon 6,6 NFM with tensile strength 5� greater (3743 MPa), and a steady-state permeability of 1667 L/(m2·h·bar) for filtration of real produced water. © 2019 by the authors.
