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.

尽管联合国宣布了水资源政策的人权，但世界上近30%的人口无法获得安全的饮用水。基于膜的水净化系统是解决全球水质差、水表面水源污染和水资源短缺问题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水净化系统的必要条件。G2O开发了一种基于氧化石墨烯的涂层技术，该技术可以很好地分离有机污染物，同时增加了通过膜的水通量。高通量和低压的结合使该技术适用于使用点水净化系统。该项目旨在通过开发一种强大的配方，将氧化石墨烯基涂层印刷到膜基上，开发一种工业上可扩展的工艺，用于制造这些膜。使用这些膜的原型模块的开发将使该联盟能够验证其性能，并在项目期间对现有系统进行基准测试。
