Wastewater Treatment Methods for Removal of Microplastics from Effluents
AI summary Read the abstract
This book chapter reviewed pressure membrane technologies — including ultrafiltration, nanofiltration, and reverse osmosis — for removing microplastics and nanoplastics from wastewater effluents. The authors evaluate the performance, cost, and limitations of each membrane type and discuss how combinations of technologies can achieve higher removal efficiencies.
Microplastics and nanoplastics (plastic debris) were found in the air, soil, and all types of water. They have a negative effect on nature, humans, and technical devices functionality. Their effective removal is therefore a great challenge. The main aim of this chapter is to discuss the pressure membrane technologies and their utilization for microplastics and nanoplastics removal. The porous and non-porous membrane types, their construction, and mechanisms of fluid transport across them are briefly described. Utilization of main pressure membrane technologies – microfiltration, ultrafiltration, nanofiltration, reverse osmosis, and electrodialysis for micro and nanoplastics capturing are discussed. Problems of membrane fouling by basic mechanisms are solved. The modeling and simulation of membrane filtration of dispersion containing solid plastic debris of different size distributions are mentioned.

Remediation of Micro- and Nanoplastics by Membrane Technologies
AI summary Read the abstract
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.

Membrane Processes for Microplastic Removal
AI summary Read the abstract
This review evaluates the use of membrane technologies for removing microplastics and nanoplastics from wastewater treatment plant effluents. Researchers found that while membrane bioreactors show promise, most existing membrane approaches are still insufficient for comprehensive microplastic removal, especially for the smallest particles. The study suggests that specially designed membrane systems are needed as advanced tertiary treatment to prevent microplastic discharge into waterways.
