This Small Business Innovation Research (SBIR) Phase I project addresses the global contamination issues of per- and poly-fluoroalkyl substances (PFAS) – also known as “forever chemicals” – in drinking water resources. The technology aims to develop a proof-of-concept, cost-effective technology that destroys PFAS chemicals even at very low levels and converts them to non-toxic. benign products in an ambient environment. Ultimately, the project team aims to provide improved water sustainability and safeguard public health. The project is aligned with the American Innovation and Competitiveness Act by advancing of the health and welfare of the American public. Initial demonstration of these impacts is expected to be felt in the water-scarce and economically fast-growing inland southern California region for both centralized and decentralized water treatment. This effort focusses on the development of a highly efficient and cost-effective photochemical treatment system for the destruction of PFAS in drinking water resources. Using a novel tunable deep ultraviolet light (a.k.a. vacuum ultraviolet or VUV), the technology aims to achieve nearly complete destruction of PFAS without generating secondary waste streams or toxic byproducts in drinking water. VUV light is one of the most accessible and efficient water ionization photon sources because it takes advantage of abundant water molecules as photon sensitizers, can be readily generated from common UV lamps, and is easy to control and operate. Tuning this light source in conjunction with other benign chemicals creates a highly reactive environment for efficient destruction of PFAS, converting waterborne PFAS into non-toxic fluoride. The effort will involve combination of chemical kinetics investigation, advanced chemical analysis, and technology scale-up in collaboration with potential customers.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这项小型企业创新研究（SBIR）I阶段项目涉及饮用水资源中的全球污染问题（PFAS）（PFAS）（PFAS）（也称为“永远的化学物质”）。该技术旨在开发一种概念验证，具有成本效益的技术，该技术即使在非常低的水平上破坏PFAS化学物质，并将其转化为无毒。在环境环境中的良性产品。最终，项目团队旨在提供改善的水可持续性和保护公共卫生。该项目通过推进美国公众的健康和福利来与《美国创新与竞争力法》保持一致。预计在水砂和经济增长的内陆内陆地区，将对这些影响进行初步证明，用于集中和分散的水处理。这项工作重点是开发一种高效且具有成本效益的光化学处理系统，以破坏饮用水资源中的PFA。该技术使用新型的可调深紫外线（又名真空紫外线或VUV），旨在在不产生次要废物流或饮用水中有毒的副产品的情况下几乎完全破坏PFA。 Vuv Light是最容易获得，最有效的水电离光子源之一，因为它利用了丰富的水分子作为光子传感器，可以很容易地从常见的UV灯中产生，并且易于控制和操作。将这种光源与其他良性化学物质结合使用，创造了一个高度反应性的环境，以有效破坏PFA，将水寄水的PFA转化为无毒的氟化物。这项工作将涉及与潜在客户合作的化学动力学调查，高级化学分析和技术规模扩大的结合。该奖项反映了NSF的法定任务，并使用基金会的智力优点和更广泛的影响审查标准，通过评估诚实地认为通过评估来诚实。
