Low Cost Printed Graphene-Oxide Membranes for Water Purification

尽管联合国宣布了水权政策，但世界上近30%的人口无法获得安全饮用水。膜基净水系统是解决水质差、水生地表水源污染和水资源短缺等全球性挑战的关键技术解决方案。克服传统膜材料的固有局限性，以低成本净化受污染的水，同时保持高水通量，是提供下一代使用点净水系统所必需的。G2O开发了一种基于石墨烯氧化物的涂层技术，该技术显示出对有机污染物的出色分离，并增加了通过膜的水通量。高通量和低压力的结合使该技术适用于使用点净水系统。该项目旨在开发一种工业上可扩展的制造这些膜的工艺，方法是开发一种用于将GO基涂层印刷到膜基材上的坚固配方。使用这些薄膜开发原型模块将使财团能够在项目期间验证其性能并将其与现有系统进行基准比较。

Despite the UN's declared Human Right to Water Policy, almost 30% of the world's population does not have access to safe drinking water. Membrane-based water purification systems are a critical technology solution to address the global challenges of poor water quality, pollution of aquatic surface water sources, and water scarcity. Overcoming the inherent limitations of conventional membrane materials to purify contaminated water at low cost while retaining high water flux is necessary to provide the next generation of point-of-use water purification systems. G2O has developed a graphene oxide based coating technology that has shown excellent separation of organic contaminants along with increased water flux through the membranes. The combination of high throughput and low pressure makes the technology suitable for point-of-use water purification systems. The project aims to develop an industrially scalable process for manufacturing of these membranes via development of a robust formulation for printing the GO-based coating onto the membrane substrate. Development of prototype modules using these membranes will allow the consortium to validate its performance and benchmark it against incumbent systems during the project.
