Micro- and Nanoplastics (MNPs) Pollutant Removal from Saline Water
AI summary Read the abstract
This review covers methods for removing micro- and nanoplastics from saline water, examining various treatment technologies suited to seawater environments. It discusses the sources and properties of MNPs and evaluates the effectiveness of available removal approaches.
Micro- and nanoplastics (MNPs) have been recognized as emerging pollutants in various water bodies/sources, especially seawater. MNPs are generated through the degradation or fragmentation of plastic debris. Plastic polymers produced for specific purposes such as microbeads, capsules, fibers, or pellets also result in MNPs contaminated wastewater. Removal of MNPs contamination from saline water and wastewater is critical to the downstream processes. This chapter presents the sources and occurrence of MNPs in saline and industrial wastewater. Different treatment technologies to remove MNPs are classified and discussed in detail. Methods like density separation, filtration, and membrane operation, already prevalent as secondary or tertiary wastewater treatment, can be implemented with adequate modification to remove MNPs from saline water. Emerging technologies like dynamic membrane, electrocoagulation, and magnetic extraction have also shown potential for MNPs recovery. Research and development toward removing MNPs from various water sources, particularly saline, discussed in this chapter, can help researchers and stack holders for adequate management of these less-discussed new class of pollutants.

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.

AI summary Read the abstract
This review examines technologies for removing nanoplastics from water, noting that conventional treatment processes effective for larger plastics often fail to capture these tiny particles. Researchers evaluated emerging methods including microbial degradation, membrane filtration, and photocatalysis, finding that combined approaches offer the best removal rates. The study highlights that more research is needed to develop practical, large-scale solutions for nanoplastic contamination in drinking water and wastewater.
