Occurrence, Fate, and Removal of Microplastics in Sewage Treatment Plants (STPs)
AI summary Read the abstract
Researchers reviewed how sewage treatment plants handle microplastics, finding that while these facilities remove a large fraction from wastewater, they also concentrate microplastics in sewage sludge that is then spread on agricultural land — potentially transferring plastic pollution from water to soil and food systems.
Microplastics (MPs), usually plastic fragments smaller than 5 mm in size, are ubiquitous in the environment and pose an increasing threat to the entire ecosystem as an emerging micropollutant. MPs not only contribute to the accumulation of the plastics in the...

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.
Microplastics in Wastewater Treatment Plants: Occurrence, Fate and Mitigation Strategies
AI summary Read the abstract
Wastewater treatment plants (WWTPs) are major conduits for microplastics into the environment, yet even advanced treatment systems fail to fully remove the smallest particles before discharge. Understanding microplastic fate across treatment stages is essential for developing targeted mitigation strategies that reduce the tonnage of plastic particles entering rivers, soils, and ultimately the food supply.
Fate of Microplastics in Wastewater Treatment Plants
AI summary Read the abstract
This book examines how microplastics move through wastewater treatment systems, covering sources, treatment technologies, system-specific factors, and future challenges for improving removal efficiency. Understanding the fate of microplastics in wastewater infrastructure is critical because treatment plants simultaneously serve as a primary barrier against and a significant ongoing source of microplastic discharge into aquatic environments.
Occurrence, Fate and Removal of Microplastics in Wastewater Treatment Plants (WWTPs) and Drinking Water Treatment Plants (DWTPs)
AI summary Read the abstract
Both wastewater and drinking water treatment plants incompletely remove microplastics, allowing substantial quantities to pass through into receiving water bodies and tap water. This finding underscores the critical need for upgraded treatment technologies and microplastic-specific monitoring standards to protect public health.
Distribution and Removal Efficiency of Microplastics in Urban Wastewater Treatment Plants
AI summary Read the abstract
Researchers tracked microplastics through 12 treatment stages at a large municipal wastewater plant using high-throughput infrared spectroscopy, finding 83% overall removal driven primarily by gravity sedimentation in clarifier tanks, with larger, denser, and fibrous particles removed most efficiently.
