ClearRecent advances on micro/nanoplastic pollution and membrane fouling during water treatment: A review
Researchers reviewed recent advances in understanding how micro- and nanoplastics contribute to membrane fouling during water treatment processes. The study found that while membrane separation effectively removes microplastics from wastewater effluent, fouling caused by plastic particles along with dissolved organics and extracellular polymers remains a key obstacle, and understanding the fouling mechanisms is critical for improving treatment efficiency.
