Microplastic pollution has emerged as a critical environmental challenge due to the increasing accumulation of plastic particles in aquatic ecosystems and urban water networks. Among the various transport pathways, stormwater runoff from urban areas is recognized as a major contributor to the discharge of microplastics into rivers, lakes, and coastal environments. Conventional stormwater treatment systems are often ineffective in removing fine and buoyant microplastic particles, highlighting the need for advanced and sustainable filtration technologies. This study presents the conceptual design and development of a multi-layered microplastic filtration system for stormwater drains using a combination of physical filtration and adsorption-based treatment mechanisms. The proposed system integrates graded gravel and sand layers for preliminary sediment removal, followed by activated carbon and graphene oxide (GO) as the primary adsorption media for capturing fine microplastics and associated pollutants. Geotextile fabrics and stainless-steel mesh are incorporated to improve structural stability, prevent media migration, and maintain hydraulic performance. The filtration mechanism is designed to enhance the removal of suspended solids, turbidity, organic contaminants, and microplastic particles of varying sizes and morphologies. The system aims to provide a decentralized, scalable, and cost-effective solution suitable for urban stormwater management applications. Expected outcomes include improved water quality, reduction in microplastic discharge into natural water bodies, and enhanced sustainability of urban drainage infrastructure. The proposed design also highlights the potential of combining nanomaterials with conventional filtration media for advanced environmental remediation applications.
KEYWORDS
This study proposed a conceptual gravity-driven multilayer stormwater filtration system for the removal of microplastics from urban runoff. The system combines conventional filtration media with a graphene oxide–activated carbon (GO–AC) composite adsorption layer to improve pollutant retention through physical filtration and advanced adsorption mechanisms. Literature-supported performance analysis indicates that the proposed design has strong potential for effective microplastic remediation, with an expected removal efficiency of 80–90% under controlled gravity-flow conditions. The system also offers advantages such as low energy requirements, scalability, modularity, and suitability for decentralized urban stormwater management. Although the study is conceptual and does not include experimental prototype validation, the proposed filtration framework demonstrates promising potential as a sustainable and practical solution for reducing microplastic pollution in stormwater systems. Future prototype development and experimental testing are recommended to validate long-term hydraulic and adsorption performance under real stormwater conditions.
