Removal of Microplastic from Wastewater Treatment Plants
AI summary Read the abstract
This review evaluated stage-by-stage microplastic removal efficiencies across wastewater treatment plant unit processes — including screening, sedimentation, biological treatment, and tertiary filtration — and assessed emerging innovations such as membrane bioreactors and advanced oxidation to improve removal rates beyond current averages of 70–99%. Because treated wastewater effluent is a primary pathway for microplastics to reach rivers and drinking water sources, optimizing removal at these facilities is one of the highest-leverage interventions available for protecting human health.
Since water treatment facilities provide a workable alternative for expelling microplastics from the surroundings, this review examines the overall and stage-by-stage effectiveness of different water treatment techniques in expelling microplastics and the innovations...

Occurrence and Removal of Microplastics in Wastewater Treatment Plants
AI summary Read the abstract
Researchers reviewed how microplastics accumulate in wastewater treatment plants and how effectively current treatment technologies remove them, finding that while plants capture most microplastics, significant quantities still pass through into receiving waterways with each discharge cycle.
Removal of Microplastics from Wastewater
AI summary Read the abstract
Wastewater treatment plants act as both a sink and a source for microplastics, capturing large fractions but still releasing significant quantities into receiving water bodies and concentrating particles in sewage sludge spread on agricultural land. Improving removal technologies at treatment plants is one of the most impactful intervention points for reducing microplastic flux into downstream environments.
Removal of Microplastics from Wastewater
AI summary Read the abstract
Researchers reviewed how sewage treatment plants both trap and release microplastics into the environment, finding that modern treatment technologies can significantly reduce the amount of plastic particles discharged — though plants remain a key pathway for microplastics to reach waterways.
Evaluation of Microplastic Removal Efficiency in Wastewater Treatment Plants
AI summary Read the abstract
Researchers evaluate the effectiveness of wastewater treatment plants at removing microplastics from water, assessing how rising plastic production is driving increased microplastic concentrations in aquatic ecosystems and the limitations of current treatment infrastructure in addressing this persistent hazard.
Detection of Microplastic in Wastewater Treatment Plants
AI summary Read the abstract
Researchers investigated microplastic detection methods in wastewater treatment plants, finding that while these facilities capture a significant fraction of microplastics, they also concentrate and potentially redistribute particles and co-contaminants into aquatic environments through effluent and biosolids.
