ClearNorfloxacin removal by ultraviolet-activated sodium percarbonate and sodium hypochlorite: process optimization and anion effect
This paper is not about microplastics; it evaluates UV-activated chemical processes for removing the antibiotic norfloxacin from water.
Elimination of microplastics from the aquatic milieu: A dream to achieve
Researchers reviewed current methods for eliminating microplastics from aquatic environments, including membrane technologies such as ultrafiltration, nanofiltration, and microfiltration. The study assessed how microplastics interact with toxic organic chemicals, antibiotics, and heavy metals in water, compounding their environmental impact. The review suggests that while various removal technologies show promise, achieving complete elimination of microplastics from water remains a significant challenge.
Sustainable removal of contaminants of emerging concern from wastewater by the living membrane bioreactor: effect of the co-occurrence of microplastics and antibiotics
Researchers investigated a living membrane bioreactor (LMBR) for removing the antibiotic ofloxacin and oxidized polyethylene microplastics from urban wastewater, finding that the biological membrane effectively retained both contaminants of emerging concern and that microplastics acted as antibiotic carriers, with their co-presence influencing overall removal efficiency.
Magnetic nanocomposites: innovative adsorbents for antibiotics removal from aqueous environments–a narrative review
This review examines how magnetic nanocomposite materials can be used to remove pharmaceutical pollutants from water. While not directly about microplastics, the technology is relevant because microplastics in water often carry pharmaceutical residues that conventional treatment cannot fully remove. Better water filtration methods like these could help reduce human exposure to the cocktail of pollutants that microplastics transport.
Norfloxacin removal efficiency by a carbon filtration column under the influence of nanoplastics: mechanistic analysis and prediction model
Researchers designed experiments to examine how nanoplastics influence norfloxacin removal efficiency in activated carbon filtration columns used in drinking water treatment, developing a mechanistic analysis and predictive model for antibiotic leakage risk when nanoplastics act as carriers in the filtration system.
Advanced Nanotechnology in Wastewater Treatment: Investigating the Role of Nanoparticles in Pollutant Removal, Water Recovery, and Environmental Sustainability
This review examines how nanotechnology-based approaches — including nanoparticle adsorbents, nanofiltration membranes, and photocatalysts — can address persistent water pollutants including pharmaceuticals, microplastics, and heavy metals more effectively than conventional treatment methods.
Ciprofloxacin Removal Using Pillared Clays
This paper is not about microplastics; it evaluates titanium-pillared bentonite clay materials for removing the antibiotic ciprofloxacin from wastewater.
Characterization of microplastics and their interaction with antibiotics in wastewater
Researchers characterized microplastics in wastewater and investigated their interactions with antibiotics, examining how microplastic surfaces adsorb antibiotic compounds and the implications for antibiotic transport and dissemination in wastewater treatment systems.
Microplastic occurrence after conventional and nanofiltration processes at drinking water treatment plants: Preliminary results
Researchers detected microplastics in source river water and finished drinking water at three treatment plants in the Paris region, finding that standard treatment steps including coagulation-flocculation and sand filtration reduced but did not eliminate MPs. Nanofiltration achieved higher removal rates, suggesting advanced filtration is needed for near-complete MP removal from drinking water.
A review of microplastic removal from water and wastewater by membrane technologies
This review examines how membrane filtration technologies can remove microplastics from drinking water and wastewater. Researchers found that advanced membranes like nanofiltration, reverse osmosis, and membrane bioreactors are among the most effective methods for capturing microplastic particles that conventional treatment plants miss. The study compares membrane approaches with other removal methods and discusses the challenges of membrane fouling caused by microplastic accumulation.
Analysis of membrane surface after the filtration of surface water containing microplastic
Researchers tested ultrafiltration and nanofiltration membranes on real river water containing microplastics and found both membrane types completely removed plastic particles from the filtered water, though the deposited microplastics reduced water flow through the membranes over time — confirming membrane filtration as an effective but imperfect water treatment strategy.
Removal of emerging micropollutants from wastewater by nanofiltration and biofilm reactor (MicroStop)
This study evaluated a combined nanofiltration and biofiltration system for removing micropollutants from municipal wastewater as part of the MicroStop project. Advanced wastewater treatment combining biological and physical filtration can significantly reduce the discharge of microplastics and chemical micropollutants into receiving water bodies.
Assessment of Molecularly Imprinted Polymers as Selective Solid-Phase Extraction Sorbents for the Detection of Cloxacillin in Drinking and River Water
Not relevant to microplastics — this paper develops a molecularly imprinted polymer method for detecting the antibiotic cloxacillin in drinking water, with no connection to plastic particles.
Advancements in Sustainable Membrane Technologies for Enhanced Remediation and Wastewater Treatment: A Comprehensive Review
This review covers membrane filtration technologies—reverse osmosis, nanofiltration, and ultrafiltration—as methods for removing contaminants from water, with relevance to microplastic and nanoplastic removal from drinking water and wastewater. Advancing membrane-based treatment is critical for reducing the microplastic load in treated water that humans and ecosystems are ultimately exposed to.
A review on tetracycline removal from aqueous systems by advanced treatment techniques
This review covers the occurrence of tetracycline antibiotics in aquatic environments and evaluates advanced treatment technologies — including adsorption, photocatalysis, and membrane processes — for their removal, identifying the most promising approaches based on efficiency and practical scalability.
Pharmaceutically active micropollutants: origin, hazards and removal
This review summarizes existing research on pharmaceutical pollutants -- such as antibiotics, painkillers, and hormones -- found in water systems around the world. While focused on drug contamination, the paper notes that microplastics can act as carriers for these pharmaceutical chemicals, potentially concentrating them and increasing human exposure through drinking water. Conventional water treatment methods are often unable to fully remove these micropollutants.
The impact of chlorination on the tetracycline sorption behavior of microplastics in aqueous solution
Researchers found that chlorination, a common disinfection step in wastewater treatment, alters the surface chemistry of microplastics and changes their capacity to adsorb tetracycline antibiotics, with chlorinated microplastics showing modified sorption behavior that affects their role as antibiotic carriers.
Understanding and characteristics of coagulation removal of composite pollution of microplastic and norfloxacin during water treatment
The coagulation removal of microplastics and the antibiotic norfloxacin together was studied in a water treatment context, finding that the presence of microplastics altered the coagulation behavior of norfloxacin and that their combined removal was less effective than treating either pollutant alone. The results highlight composite pollution as a challenge for conventional water treatment processes.
Removal of microplastics and nanoplastics in water treatment processes: A systematic literature review
Researchers systematically reviewed 103 studies across 26 water treatment plants in 12 countries to assess how well various technologies remove microplastics and nanoplastics from drinking water, finding that while coagulation, filtration, and advanced treatments help, significant gaps remain. The review identifies that no single process achieves complete removal, leaving microplastics as a persistent contaminant in treated water supplies.
The occurence of pharmaceuticals and other micropollutants in wastewater treatment plant in the aspect of interaction with microplastics
Researchers analysed the occurrence of antibiotics, virucidal, and fungicidal pharmaceuticals in raw and treated sewage at a wastewater treatment plant in southern Poland, examining their removal efficiency and potential interactions with microplastics present in the effluent. The study found that pharmaceutical micropollutants persisted through treatment to varying degrees, raising concerns about combined contamination pathways when microplastics act as co-vectors for these compounds.
