Limitations of Current Remediation Technologies for Aquatic Microplastics and the Case for Integrated Treatment Systems
AI summary Read the abstract
This review paper looks at the current methods for removing tiny plastic particles from our water—like filtering, chemical treatments, and using microbes to break them down—and finds that none of them work well enough on their own to fully clean up the mess. The takeaway is that tackling microplastic pollution in our water supply, which matters because these particles have been found in human blood and organs, will likely require combining multiple treatment steps rather than relying on a single fix.
The accumulation of micro- and nanoplastics in aquatic environments represents a legacy pollution burden that source-reduction measures alone cannot address. This paper evaluates the operational envelopes and mechanical limitations of physical separation (coagulation-flocculation, deep-bed filtration, and membrane bioreactors), advanced oxidation processes (Fenton, photocatalysis, and ozonation), and biological degradation pathways. No single technology provides a complete solution across diverse particle distributions; this work outlines the structural case for staged, hybrid treatment trains to achieve genuine biospheric mineralization.

Limitations of Current Remediation Technologies for Aquatic Microplastics and the Case for Integrated Treatment Systems
AI summary Read the abstract
Tiny plastic particles have already built up in our lakes, rivers, and oceans—and eventually in our drinking water and food chain—so just making less plastic won't undo the damage already there. This review looked at existing cleanup methods (like filtering, chemical treatments, and using microbes to break plastic down) and found that none of them alone can fully remove or destroy these particles. The takeaway: cleaning up water supplies will likely require combining several methods together, which matters because reducing microplastics in our water is a key step toward reducing our own exposure to them.
Microplastics in aquatic systems: An in-depth review of current and potential water treatment processes
AI summary Read the abstract
This review provides a detailed examination of microplastic contamination in aquatic systems and evaluates current and emerging water treatment technologies for their removal. Researchers assessed methods ranging from conventional coagulation and filtration to advanced techniques like membrane bioreactors and electrochemical processes. The study concludes that while no single technology fully eliminates microplastics, combining multiple treatment approaches offers the most promising path forward.
Nanoplastics in water and wastewater: remediation technologies, challenges, and future perspectives
AI summary Read the abstract
This review paper examines methods for removing tiny plastic particles, called nanoplastics, from water and wastewater. It finds that techniques like filtration and chemical treatment often just move the particles elsewhere rather than destroying them, while advanced chemical treatments can break them down under certain conditions. The authors say more testing in real water systems is needed to confirm which methods truly remove nanoplastics.
Critical review of microplastics removal from the environment
AI summary Read the abstract
This review evaluates technologies for removing microplastics from the environment, including physical methods like filtration, chemical treatments, and biological approaches using microorganisms. Each method has trade-offs between effectiveness, cost, and scalability, and no single technology can solve the problem alone. The authors emphasize that reducing human exposure to microplastics requires combining better removal technologies with policies that limit plastic production and waste at the source.
Tackling microplastics pollution in global environment through integration of applied technology, policy instruments, and legislation
AI summary Read the abstract
This review examines the global microplastics pollution problem and evaluates solutions combining technology, policy, and legislation. Current water treatment technologies like membrane bioreactors can remove microplastics, but no single approach is sufficient. The authors call for coordinated international action combining better detection methods, cleanup technologies, and stronger regulations to address plastic pollution in both water and land environments.
