The broader impact of this SBIR Phase II project is in the creation of a much-needed alternative to biosolids disposal. Biosolids are a by-product of wastewater treatment; their formation and disposal contribute to significant air, water, and soil pollution. In particular, biosolids contribute to greenhouse gas emissions and the release of over 350 organic contaminants, including high concentrations of per- and polyfluoroalkyl substances (PFAS). Biosolids disposal challenges are expected to grow due to population increases and stricter environmental regulations. Current biosolids disposal options have shortfalls and disposal costs are increasing. This project develops a breakthrough technology that cleanly and affordably destroys the organic contaminants present in biosolids. Air, water and soil pollution will be reduced, and, importantly, wastewater treatment plants will be able to meet new regulatory standards for sustainability. Volume of final by-product, and therefore transport cost and associated emissions, will be decreased by over 85%.The proposed project turns supercritical water oxidation (SCWO) into an energy-efficient technology by recovering compressive energy. SCWO rapidly and completely destroys organics. To date, the technology has been used in few applications, including chemical weapons dismantling. Recovery of compression energy saves 30-40% of total treatment cost, opening new markets, such as wastewater treatment. Recovery of compression energy during SCWO has been demonstrated previously. This project's goals are to further optimize, scale-up and iterate on compression energy recovery equipment for added capacity and reliability, and long-term field test these updated/new pieces of equipment by adding them to an existing supercritical water oxidation pilot system. The goal for the system is to achieve reliability on par with industrial high-pressure compressors, which can operate over 24,000 hours between major services.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.

该SBIR II期项目的更广泛影响是创建了一种急需的生物固体处置替代品。生物固体是废水处理的副产品。它们的形成和处置有助于空气，水和土壤污染。特别是，生物固体有助于温室气体排放，并释放350多种有机污染物，包括高浓度的人类和多氟烷基物质（PFA）。由于人口增加和更严格的环境法规，预计生物固体处置挑战将增加。当前的生物固体处置方案有短缺，处置成本正在增加。该项目开发了一项突破性技术，可干净，负担得起的生物固体中存在的有机污染物。空气，水和土壤污染将减少，重要的是，废水处理厂将能够符合新的可持续性监管标准。最终副产品的数量，因此运输成本和相关的排放量将减少超过85％。拟议的项目通过回收压缩能将超临界水氧化（SCWO）变成一种节能技术。 SCWO迅速，完全破坏有机物。迄今为止，该技术已用于少数应用，包括拆除化学武器。恢复压缩能量可节省30-40％的总治疗成本，开放新市场，例如废水处理。 先前已经证明了SCWO期间的压缩能的恢复。 该项目的目标是通过将它们添加到现有的超临界水氧化试验系统中，进一步优化，扩展和迭代以增加容量和可靠性，并在压缩能恢复设备上进行增强的能力和可靠性。该系统的目的是与工业高压压缩机相当地实现可靠性，该压缩机可以在主要服务之间运行24,000多个小时。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子和更广泛影响的评估评估来获得支持的。
