Microplastics (MPs) in everyday consumer products have paved the way for high MPs concentrations wastewater. Wastewater treatment plants (WWTP)s are significant focal points MP pollution, as millions of particles with varying characteristics enter WWTPs through sewage systems urban areas. Although units not primarily designed to target specifically, researchers reported a large amount microplastic removal from various WWTPs. The scientific community has remarkably studied conventional and advanced methods remediate nanoplastics (NPs) This review aims provide comprehensive knowledge about source NPs wastewater, their composition, toxic effects, remediation comprise several physical, chemical, biological processes broadly categorized into three key stages: primary, secondary, tertiary. interaction these also been reviewed. Literature indicates that can separate more than 90% However, despite low treated effluent, discharge volumes contribute MPs/NPs environment. Also, separated re-enter environment sludge applied on land. paper discusses application wastewater technologies efficacies remediating microplastics. Finally, highlights research gaps where additional exploration is required, providing new perspective developing policies controlling pollution.

Abstract Synthetic textiles are a significant source of microplastic fibre pollution. While the release mechanism during washing is well studied, little known about nanoplastics. The first investigations on nanoplastic fraction released and abrasion polyester have been published; however, questions were raised regarding chemical composition observed submicrometre particles. Using combination analytical methods, we show here that 12 different 4.6 × 10 to 8.9 11 particles per gram textile washing, with mean size 122–191 nm. number was not significantly influenced by cutting method nor structure, but positively correlated ( P < 0.01) present surface before washing. We found 34–89% extracted soluble in ethanol. These most likely water-insoluble poly(ethylene terephthalate) oligomers. Our results clearly urgent need better understand contribution oligomer pollution environment anthropogenic

Water treatment plants' effluents are hotspots of microplastics (MPs) and microfibres (MFs) released into the aquatic environment because they were not designed to capture these particles. Special attention should be given MFs, since mainly come from laundry related one main MP shapes detected in water wastewater plants. In this sense, Advanced Oxidation Processes (AOPs) could a feasible solution for tackling MF pollution, however, it is still premature extract conclusions due limited number studies on degradation particles (specifically MFs) using AOPs. This review addresses impacts AOPs MPs/MFs, focusing their efficiency, toxicity, sustainability processes, among other aspects. The points out that polyamide MFs can achieve mass loss >90% by photocatalytic system TiO2. Also, low oxidation MPs (<30 %) conventional Fenton process affects surface MPs. However, Fenton-based processes provide better removal some types MPs, temperatures >100 °C, reaction time ≥ 5 h, initial pH ≤ 3, achieving weight up 96 %. Despite results, operating conditions required ones reported so far full-scale application. Additionally, ozonation plants has increased fragmentation (including MFs), leading new generation More needed toxicity effects intermediates methods analysis employed MPs/MFs effluent standardized compared effectively. Future research focus AOP (power consumption, chemicals consumed operational costs) understanding applicability adapted treatment.

Microplastics detected in potable water sources and tap have led to concerns about the efficacy of current drinking treatment processes remove these contaminants. It is hypothesized that resources contain nanoplastics (NPs), but detection NPs challenging. We, therefore, used palladium (Pd)-labeled investigate behavior removal during conventional including ozonation, sand activated carbon filtration. Ozone doses typically applied plants (DWTPs) hardly affect transport subsequent filtration systems. Amongst different media, particles were most efficiently retained when aged (i.e. biofilm coated) was with good agreements between laboratory pilot scale The through multiple steps a municipal full-scale DWTP simulated using MNMs software code. Removal efficiencies exceeding 3-log units modeled for combination three consecutive (rapid filtration, slow 0.4-, 0.2- 3.0-log-removal, respectively). According results from model, dominated overall which also supported by laboratory-scale pilot-scale data. this study can be estimate efficiency typical DWTPs similar chains.
