Seasonal variation and removal efficiency of microplastics in wastewater treatment: a year-long study across three municipal water reclamation plants

Environmental Science Water Research & Technology 2025 2 citations

AI summary Read the abstract

A year-long study across three municipal water reclamation plants found significant seasonal variation in microplastic concentrations and removal efficiencies, with effective but incomplete removal leaving residual microplastics in effluent that posed low to medium ecological risks to receiving water bodies.

Study Type Environmental

This study investigates the seasonal variations and removal efficiency of microplastics (MPs) in the wastewater of three water reclamation plants. Despite effective removal, MPs were still found in the effluent, posing low to medium ecological risks.

Microplastic distributions in a domestic wastewater treatment plant: removal efficiency, seasonal variation and influence of sampling technique

AI summary Read the abstract

Researchers monitored microplastic concentrations throughout a municipal wastewater treatment plant over a full year, finding that the plant removed the majority of incoming microplastics but still released millions of particles daily in its effluent. Seasonal variation and sampling method were found to influence the results significantly.

Microplastic distributions in a domestic wastewater treatment plant: Removal efficiency, seasonal variation and influence of sampling technique

AI summary Read the abstract

A year-long study of a municipal wastewater treatment plant found 97% removal efficiency for microplastics overall, but fibers made up a larger proportion of remaining particles in treated water than in raw sewage, and winter samples had notably higher microplastic concentrations. The study highlights seasonal variation as an important factor in assessing wastewater microplastic loads.
