A full-process analysis at a wastewater treatment plant in Hohhot, China found that fibrous microplastics were most abundant, accounting for 61.8 percent of total particles, with particle size and abundance changing across treatment stages. The study maps how microplastics migrate and what fraction is removed by each treatment step.
Occurrence and Removal of Microplastics in Tertiary Wastewater Treatment Plants: A Case Study of Three Plants in Zhengzhou, China
Researchers studied microplastic occurrence and removal efficiency at three wastewater treatment plants in Zhengzhou, China. The study found influent concentrations ranging from 147 to 289 particles per liter, with removal efficiencies between 76% and 91%, indicating that while treatment plants significantly reduce microplastic levels, substantial quantities still pass through to receiving waters.
Occurrence and Characteristics of Microplastics in a Wastewater Treatment Plant
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.

Researchers investigated microplastic abundance and removal efficiency across treatment stages at a wastewater treatment plant in Zhengzhou, China, sampling sewage at each processing section to track migration and fate of microplastics. The study characterized removal rates and identified which treatment stages were most effective at capturing microplastic contaminants.
Abundance, morphology, and removal efficiency of microplastics in two wastewater treatment plants in Nanjing, China
Researchers investigated microplastic abundance, morphology, and removal efficiency at two wastewater treatment plants in Nanjing, China, finding four microplastic shapes including fragments, granules, films, and fibres across varying sizes and proportions. The study examined how treatment technology, operational parameters, and sewage source characteristics influenced microplastic removal rates.
Occurrence and fate of microplastics from a water source to two different drinking water treatment plants in a megacity in eastern China
Researchers tracked microplastics through two drinking water treatment plants in a major Chinese city and found that treatment removed 73-83% of microplastics from the water. However, some microplastics were still present in the treated drinking water, and chlorine disinfection actually increased polystyrene levels. The smallest particles (2-5 micrometers) were the hardest to remove, which is a concern because smaller particles may be more easily absorbed by the human body.
The Pollution Characteristics and Fate of Microplastics in Typical Wastewater Treatment Systems in Northern China
Researchers analyzed microplastic contamination at two wastewater treatment plants in Zhengzhou, China, finding overall removal efficiencies of about 93 and 96 percent respectively. Fibers and fragments were the most common microplastic shapes detected, with much of the removed material ending up concentrated in sewage sludge. The study raises concerns that while treatment processes are effective at reducing waterborne microplastics, the contaminated sludge may redistribute the pollution when applied to agricultural land.
Distribution characteristics of microplastics in wastewater treatment plants in mega cities–the case study of Chengdu City
Researchers studied microplastic distribution and removal across wastewater treatment plant processes in China, finding that WWTPs intercept large quantities of MPs before discharge but that residual concentrations in effluent still represent a significant pathway for environmental MP release.
Abundance, Characteristics, and Removal of Microplastics in Wastewater Treatment Plant located in Southwest China
Researchers investigated microplastic abundance, characteristics, and removal efficiency at a wastewater treatment plant in Leshan, Southwest China, finding influent concentrations of 267.74 particles/L reduced to 68.34 particles/L in effluent, achieving a 74.48% total removal rate, with smaller particles (0.05-0.3 mm) being the most prevalent and hardest to remove.
Spatiotemporal Distribution Characteristics and Removal Efficiency of Microplastics in a Wastewater Treatment Plant
Researchers examined microplastic removal efficiency across three seasons at a wastewater treatment plant in Zhengzhou, China, sampling influent, process effluent, and final effluent. They found an overall removal efficiency of 86%, with polypropylene and polyethylene terephthalate as the dominant polymer types and fragment- and granule-shaped particles comprising over 80% of microplastics detected.
[Removal of Microplastics by Different Treatment Processes in Shanghai Large Municipal Wastewater Treatment Plants].
A study of two large wastewater treatment plants in Shanghai found that microplastic concentrations in incoming sewage were very high, and overall removal efficiency ranged from 63% to 90% depending on treatment processes. Even with high removal rates, large volumes of microplastics are still discharged to waterways daily.

Researchers characterized microplastic contamination at various stages of a wastewater treatment plant in Hefei, China, under both dry and rainy weather conditions. They found that while the treatment process removed a significant portion of microplastics, notable amounts still passed into the effluent, with rain increasing contamination levels. The study provides a detailed assessment of how effectively current wastewater treatment technology handles microplastic pollution.
Influence of wastewater treatment process on pollution characteristics and fate of microplastics
Researchers investigated microplastic abundance and removal efficiency across four wastewater treatment plants using different treatment technologies, finding influent concentrations between 539 and 1,290 particles per liter that were reduced substantially by primary and secondary treatment. Smaller microplastic particles proved hardest to remove and most likely to persist in final effluent.
