Development of crosslinked polyvinyl alcohol nanofibrous membrane for microplastic removal from water
Researchers developed a crosslinked polyvinyl alcohol nanofibrous membrane capable of removing microplastics and lead from drinking water. The membrane achieved over 99% removal efficiency for microplastics larger than one micrometer while maintaining good water flux, showing promise as a point-of-use filtration device.
Designing poly(vinylidene fluoride) membranes with narrow pore size distribution for microplastics removal from water
Scientists developed an improved method for making water filtration membranes with very uniform pore sizes, specifically designed to capture tiny microplastic particles. Using a common polymer (PVDF) and a straightforward manufacturing process, the membranes achieved over 97 percent removal of microplastic particles as small as 500 nanometers. The study suggests this approach could offer a practical and scalable solution for filtering microplastics from drinking water and wastewater.
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.
Effects of microplastic on submerged nanofiltration for advanced drinking water treatment
Researchers investigated how microplastics in reservoir water affect the performance of submerged nanofiltration membranes used for drinking water treatment. The study found that the presence of polyethylene terephthalate microplastics influenced the removal of dissolved organic matter by the membrane, with implications for optimizing advanced water treatment processes.
Carbon nanoparticles fabricated microfilm: A potent filter for microplastics debased water
Researchers developed a carbon nanoparticle membrane combined with a PVDF polymer to filter microplastics from water. The nanofilm effectively removed microplastics, reduced microbial contamination, and improved water clarity. The study highlights nanofiltration as a promising low-cost approach for removing microplastics from water, with efficiencies reaching up to 95%.
