Partitioning of removal of microplastics and other anthropogenic particles among influent, biosolids and final effluent in a tertiary wastewater treatment plant
Researchers tracked the partitioning of microplastics and other anthropogenic particles across influent, biosolids, ultrafiltration membrane flows, and final effluent in a tertiary wastewater treatment plant, finding that 99% of particles were retained in biosolids while fewer than 1% passed through to final effluent. The study revealed that fiber morphologies dominated influent and effluent while fragments dominated biosolids, and that ultrafiltration membrane performance varied with operational condition.
Enrichment of nutrients from anaerobically digested centrate minimizing microplastics content using a combination of membrane processes
Researchers analyzed microplastic content in centrate — the nutrient-rich liquid effluent from sludge dewatering in wastewater treatment plants — and applied ultrafiltration and forward osmosis membrane processes to simultaneously concentrate nutrients and reduce microplastic contamination. The study demonstrated that combining membrane technologies can effectively minimize microplastic content in centrate while enriching ammonium-nitrogen and phosphates for potential nutrient recovery applications.

Technologies for the Removal of Microplastics from Wastewater: A Short Review
This review compares wastewater treatment technologies for removing microplastics, finding that membrane bioreactors and advanced filtration systems achieve the highest removal efficiencies (>95%) but that MPs accumulating in sludge may re-enter the environment through biosolid disposal. The analysis underscores that no current treatment system completely prevents MP discharge and that sludge management is a critical but underaddressed pathway to the environment.

This review examines the sources, environmental impacts, and treatment methods for microplastic contamination, with a focus on ceramic membrane filtration. Researchers found that while conventional treatment methods have limitations, ceramic membranes offer cost-effective and durable performance for removing microplastics from water. The study highlights the widespread presence of microplastics across environmental compartments and the urgent need for scalable removal technologies.
Microplastics removal through water treatment plants: Its feasibility, efficiency, future prospects and enhancement by proper waste management
Researchers reviewed over 80 studies on water treatment plant performance and found microplastic removal ranges widely — from 16% in basic primary treatment up to near 100% with advanced membrane systems — but a major flaw is that removed microplastics concentrate in sludge, which can re-enter the environment. The review recommends optimizing coagulants and sludge treatment to prevent microplastics from simply being relocated rather than eliminated.
