PVA-GO Membrane for the Treatment of Microplastics in Wastewater

Microplastics are pervasive environmental pollutants, posing threats to both ecosystems and human health. This study investigates the presence and fate of microplastics in wastewater treatment plants (WWTPs) as potential contributors to environmental contamination. Sampling from two WWTPs in Erode over a 7-day winter period yielded 14 samples for analysis. Results indicate effective microplastic removal by WWTPs, yet incomplete treatment allows residual microplastics to persist in the environment due to their small size and lightweight nature. To address this issue, advanced treatment technologies, such as membrane-based processes and advanced oxidation methods, are proposed. Specifically, this study investigates the modification of polymer-based membranes, such as poly sulfone (PSF) combined with graphene oxide (GO), with the addition of polyvinyl alcohol (PVA) and GO to enhance microplastic removal efficiency. This novel approach aims to provide cost-effective solutions for microplastic mitigation in wastewater. Additionally, the study explores the potential for wastewater characterization for reuse applications, expanding the sustainability of wastewater management practices. Future research should focus on optimizing membrane modification techniques to maximize microplastic removal efficacy. This interdisciplinary study contributes valuable insights into mitigating microplastic pollution and promoting environmental and human health.
