Article Synopsis
- Large volumes of water contaminated with hydrocarbons and chemicals during oil & gas exploration create a complex wastewater stream known as produced water (PW), which presents treatment challenges due to membrane fouling.
- Nanofiltration membranes based on polyelectrolyte multilayers (PEM) show promise for treating PW, where the study examines how different surface chemistries affect fouling when using oil-in-water emulsions stabilized with various surfactants.
- Results indicate that fouling primarily occurs due to surfactants being absorbed into the membrane coating rather than cake layer formation, suggesting that membrane surface chemistry impacts surfactant retention and fouling extent.
