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.

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.
