Enhanced membrane fouling by microplastics during nanofiltration of secondary effluent considering secretion, interaction and deposition of extracellular polymeric substances
Researchers found that microplastics significantly worsen membrane fouling during nanofiltration of treated wastewater, increasing both short-term and long-term fouling resistance by up to 46% and 27% respectively. The study reveals that microplastics influence fouling through their effects on bacterial extracellular polymeric substance secretion, interaction with coexisting pollutants, and deposition on membrane surfaces.
Nano/microplastics in water and wastewater treatment processes – Origin, impact and potential solutions
This review examined the origin, fate, and impacts of nano- and microplastics in water and wastewater treatment processes, finding that small particle sizes and diverse polymer compositions make complete removal challenging across conventional and advanced treatment stages. The authors identify detection limitations and process instability as key barriers to effective water treatment for nanoplastics.
Micro- and nanoplastics removal mechanisms in wastewater treatment plants: A review
This review examines how conventional wastewater treatment plants remove micro- and nanoplastics, and evaluates advanced technologies like membrane filtration and electrocoagulation that could improve removal rates. While existing treatment plants can capture most microplastics, they still release significant quantities into waterways through their enormous discharge volumes. The study highlights that biological treatment steps may also transform microplastics in potentially harmful ways that need further investigation.
Remediation of Micro- and Nanoplastics by Membrane Technologies
This review examined how membrane filtration technologies can remove micro- and nanoplastics from water and wastewater, since conventional treatment plants cannot fully eliminate these particles. Researchers found that techniques like ultrafiltration, nanofiltration, reverse osmosis, and membrane bioreactors are highly effective at capturing microplastics, though each has trade-offs related to cost, fouling, and energy use. The study also raises the concern that polymeric membranes themselves could potentially release plastic particles during the filtration process.

Fouling behavior of nano/microplastics and COD, TOC, and TN removal in MBR: A comparative study
This study tested a membrane bioreactor (MBR) — a combination of biological treatment and membrane filtration used in wastewater plants — for its ability to remove nano- and microplastics from wastewater. The system achieved 99.4% removal of organic pollutants and complete removal of nanoplastics, and found that more hydrophilic membranes were better at capturing microplastics. The study also examined how microplastics foul and clog membranes over time, which is a practical challenge for wastewater treatment operations. These results support MBRs as a promising technology for reducing microplastic discharges from treatment plants into waterways.
