ClearThe impact of ozonation on PET and PVC microplastics in model urban wastewater
Researchers investigated the effects of 6-hour ozonation treatment on PET and PVC microplastics in model urban wastewater, evaluating ozonation as an advanced oxidation process for microplastic degradation and assessing changes in polymer structure and surface chemistry for both plastic types.

Ozone-mediated breakdown of microplastics in aqueous environments
Researchers examined how ozone-based advanced oxidation processes break down microplastics in water treatment settings. They found that while ozone can degrade certain plastics, the effectiveness varies depending on particle size, polymer type, and treatment conditions, and the process may generate nanoplastic byproducts. The study highlights both the promise and limitations of ozone treatment as a strategy for removing microplastics from wastewater.
Oxygen plasma treatment to mitigate the shedding of fragmented fibres (microplastics) from polyester textiles
Researchers found that treating polyester fabric with oxygen plasma — a sustainable, chemical-free process — reduced the shedding of microplastic fibers by 43% in mass and 73% in count by increasing fiber surface friction. This discovery offers a practical way to cut microplastic pollution from synthetic textiles without harming fabric quality.

Researchers evaluated ozone oxidation as a method for removing microplastics from urban wastewater treatment plant effluent, using Taguchi experimental design to optimize the process. The study identified optimal conditions of pH 7 with specific ozone doses and reaction times for effective microplastic removal, demonstrating that ozone treatment could be a viable approach for reducing microplastic discharge from wastewater facilities.
Effective Removal of Microplastics Using a Process of Ozonation Followed by Flocculation with Aluminum Sulfate and Polyacrylamide
Researchers tested a two-step water treatment process combining ozonation with flocculation to remove microplastics. They found that ozone pretreatment roughened the microplastic surfaces and added chemical groups that dramatically improved removal rates, from 40% to 91%, during the subsequent flocculation step. The findings suggest this combined approach could significantly enhance microplastic removal in conventional water treatment plants.
Changes in physical and chemical properties of microplastics by ozonation
Researchers examined how ozone treatment in water systems changes the physical and chemical properties of six common types of microplastics. They found that ozonation altered surface roughness, wettability, and chemical composition of the plastics, with some types being more affected than others. The findings are important because these changes could influence how microplastics interact with other pollutants and organisms in treated water.
