ClearAerobic Biological Treatment of Microconstituents
This chapter reviews aerobic biological treatment systems and their effectiveness at removing trace organic micropollutants (including pharmaceuticals and personal care products) from wastewater. Biological treatment processes are also relevant to removing microplastics and their associated chemical contaminants from municipal wastewater.
Application of biofilm-membrane bioreactor in municipal wastewater treatment
Researchers designed and tested a biofilm-membrane bioreactor system for municipal wastewater treatment, using a Fourier series algorithm to model performance against COD and ammonium nitrogen removal metrics.

Submerged membrane/adsorption hybrid process in water reclamation and concentrate management—a mini review
Researchers review how combining membrane filtration with adsorption — a process where pollutants stick to a material's surface — creates a hybrid water treatment system that outperforms either method alone. This integrated approach is particularly effective at removing hard-to-treat organic pollutants from wastewater, including trace pharmaceuticals and industrial chemicals that conventional treatment misses.

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.
