A mini-review on discharge characteristics and management of microplastics in sewage treatment plants
AI summary Read the abstract
This Chinese mini-review examines the characteristics and removal efficiency of microplastics in sewage treatment plants, and discusses the risks associated with microplastics in effluents and their effects on the organisms in receiving waters. It provides context for why routine monitoring of microplastics in wastewater is being initiated.
As the issue of microplastics (MPs) detection in tap water was raised in other countries in 2017, monitoring of MPs in drinking and source water, and sewage treatment plant (STP) effluents was initiated. This study intends to look into other studies on MPs in STPs at home and abroad, and review the characteristics of MPs and their removal efficiencies in the STPs, the risk and effect of MPs on watersheds, and management practices in order to help better understand MPs in STPs. To manage MPs effectively in STPs, it is necessary to investigate the detection of MPs discharged from STPs, do research on human health risk and control measures, and build a monitoring system including standardized analytical methods.

This review summarizes the occurrence, characteristics, and removal efficiency of microplastics in wastewater treatment plants, highlighting how these facilities simultaneously act as sinks trapping microplastics and as sources releasing them into surrounding aquatic and terrestrial environments.
Characteristics and removal efficiency of microplastics in sewage treatment plant of Xi'an City, northwest China
AI summary Read the abstract
Researchers systematically tracked microplastic transport, characteristics, and removal through both the sewage and sludge treatment streams of a Chinese wastewater treatment plant. The study found that while most microplastics were removed from effluent, substantial quantities accumulated in sludge.
Microplastics in Wastewater Treatment Plants (WWTPs): A Review
AI summary Read the abstract
This review examines the occurrence and behavior of microplastics in wastewater treatment plants (WWTPs), finding that while WWTPs remove a large proportion of incoming microplastics, they still discharge significant quantities into receiving water bodies daily. The paper calls for improved treatment technologies and better characterization of microplastic types in wastewater streams.
Occurrence and Characteristics of Microplastics in a Wastewater Treatment Plant
AI summary Read the abstract
Researchers sampled the inflow, outflow, and sludge of a Chinese wastewater treatment plant, finding up to 44 microplastic particles per liter in incoming water — mostly polyester fibers. The plant removed about 96% of microplastics, but the remaining fraction was still discharged into receiving waterways.
