The broader impact of this SBIR Phase II project is to demonstrate feasibility and determine the capacity of a novel advanced, high-rate wastewater treatment technology to protect environmental and public health during high-intensity storm events by eliminating sewer overflows and basement backups. Wastewater utilities need reliable, cost-effective, decentralized wastewater treatment as an alternative to expensive long-term plans that emphasize large capital projects. This project will scale and optimize a novel approach to achieve treatment equivalent to conventional methods in less than 35 minutes, compared to the current practice of 8-14 hours. A lower treatment time means a smaller system footprint and, ultimately, cost savings for the utility and ratepayers. The technology will identify sewer overflow “hotspots” where raw sewage is discharged into receiving bodies of water during storm events as an alternative to basement backups. Implementing this novel solution at overflow locations would alleviate overburdened collection, conveyance, and treatment systems by treating wet weather flows and safely discharging them into waterways. This innovative technology can also be applied at a water reclamation facility to handle overburden or as a mobile unit during disaster relief efforts. This SBIR Phase II project proposes the evaluation of novel concepts including the application of advanced oxidation processes (AOPs) for wastewater treatment, the combination of rapid solid removal technologies with AOPs, and the use of a sustainable waste material and custom cartridge supports with a catalyst for enhanced hydroxyl radical production in catalytic ozonation. None of these approaches have been commercially implemented. The work proposed will demonstrate the ability for advanced technologies to be cost-effectively applied for wastewater treatment, disrupting the standard of partial combined sewer overflow treatment by providing a viable option for rapid wet weather treatment that meets or exceeds Clean Water Act discharge standards. These concepts will be applied at an industry-relevant pilot scale to determine the technical and chemical scaling factors for a full-scale system and to demonstrate required levels of treatment while treating real wastewater. Metrics for success within the research plan include aggressive contaminants of emerging concern removal goals, increased automation and energy efficiency, and a targeted cost ($/gallon treated) analysis to ensure competitive edge in the market. The results of the project will demonstrate that decentralized permit-level treatment is feasible, reliable, and cost-effective, allowing full-scale implementations to begin.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第二阶段项目的更广泛影响是证明可行性，并确定一种新型先进的高速率废水处理技术的能力，通过消除下水道溢流和地下室备份，在高强度风暴事件期间保护环境和公众健康。废水处理设施需要可靠、具有成本效益的分散式废水处理，作为强调大型资本项目的昂贵长期计划的替代方案。该项目将扩展和优化一种新方法，以在不到35分钟的时间内实现与传统方法相当的治疗，而目前的做法是8-14小时。更短的处理时间意味着更小的系统占地面积，并最终为公用事业和纳税人节省成本。该技术将确定下水道溢流“热点”，在风暴事件期间，未经处理的污水被排放到接收水体中，作为地下室备份的替代方案。在溢流位置实施这种新颖的解决方案将通过处理潮湿天气的水流并将其安全地排放到水道中来减轻负担过重的收集，运输和处理系统。这项创新技术也可以应用于水回收设施，以处理超载或作为一个移动的单位在救灾工作。 该SBIR第二阶段项目提出了新概念的评估，包括高级氧化工艺（AOPs）在废水处理中的应用，快速固体去除技术与AOPs的结合，以及使用可持续的废物材料和定制的滤芯支持物与催化臭氧化中增强羟基自由基生产的催化剂。这些方法都没有在商业上实现。拟议的工作将证明先进技术具有成本效益地应用于废水处理的能力，通过提供符合或超过清洁水法排放标准的快速潮湿天气处理的可行选择，破坏了部分合并下水道溢流处理的标准。这些概念将应用于工业相关的试验规模，以确定全规模系统的技术和化学比例系数，并在处理真实的废水时证明所需的处理水平。研究计划中的成功因素包括新出现的污染物去除目标，提高自动化和能源效率，以及有针对性的成本（$/加仑处理）分析，以确保在市场上的竞争优势。该项目的结果将证明，分散式放射治疗是可行的，可靠的，具有成本效益的，允许全面实施开始。该奖项反映了NSF的法定使命，并已被认为是值得通过使用基金会的智力价值和更广泛的影响审查标准进行评估的支持。
