SBIR Phase II: Development of Activated Swelling Organosilica-Metal Composites Filter Media in Bioretention Systems for Enhanced Remediation of Stormwater Runoff

这项小型企业创新研究第二期计划将发展创新的水吸收生物保留系统，以加强雨水水质的修复。项目负责人杨汉培博士正在使用由俄亥俄州伍斯特的ABSMaterials公司开发的新型工程玻璃-金属混合材料来修复环境污染物。径流控制在美国是一个迫在眉睫且日益严重的问题。雨水通常含有营养物质、碳氢化合物、除草剂和药物，破坏地表水，并携带影响人类和生态系统的持久性化学物质。杨博士在控制径流污染物方面的创新，将工程玻璃(Osorb)-金属复合材料混合到生物保留系统中，已经证明了对阿特拉津、雌二醇、内分泌干扰物、BTEX和营养物质的有效性。Osorb-金属复合材料结合了两种先进的修复材料：(1)高容量有机二氧化硅吸附剂Osorb和(2)活性嵌入金属。复合材料通过从水中去除污染物来吸收污染物，并在玻璃内降解污染物。第二阶段将实现的关键技术开发包括：(1)配方优化与客户的现场测试，(2)配方性能改进，以及(3)商业化和模块化生物保留封装的开发。与旧的生物滞留系统相比，预计这些系统中的一些将在有效的雨水污染物修复方面得到数量级的改善，并为最佳管理实践设定新的标准。该项目由杨博士和ABSMaterials共同开展，其更广泛的影响和商业潜力将包括：(1)为数十个城市提供一种全新的工具，通过绿色基础设施解决下水道溢出的挑战；(2)通过降低污染雨水的处理成本，大幅减少环境污染；(3)改善水生生物和人类健康；(4)促进绿色雨水再利用。美国环保署和州政府正在强制实施许多雨水计划，以控制非点源/CSO污染。径流处理工具往往缺乏，无法满足更严格的法规要求。开发经济和有效的以吸收剂为基础的雨水解决方案将大大减少径流污染物对人类和水生健康的负面影响。西雅图估计，不受控制的雨水径流的经济影响为1.13亿美元，并计划建造12,000个生物保留系统，以减少每年1600万加仑的城市径流。其他城市，包括克利夫兰、费城、巴尔的摩和纽约，也在制定类似的绿色基础设施战略。ABSMaterials正在为高中和大学的科学课程进一步开发综合课程，并提供涉及先进材料和水修复的实习和培训经验。该公司预计在此资助期间将创造6个直接从事商业活动的新全职职位。

This Small Business Innovation Research Phase II project will develop innovative Osorb bioretention systems for enhanced remediation of stormwater quality. PI, Dr. Hanbae Yang, is using novel engineered glass-metal hybrid materials developed by ABSMaterials, Inc. of Wooster, Ohio to remediate environmental pollutants. Runoff control is an immediate and growing concern in the US. Stormwater often laden with nutrients, hydrocarbons, herbicides, and pharmaceuticals, damaging surface water and carrying persistent chemicals impacting humans and ecosystems. Dr. Yang's innovations for controlling runoff pollutants using engineered glass (Osorb)-metal composites mixed into bioretention systems have demonstrated effectiveness on atrazine, estradiol, endocrine disruptors, BTEX, and nutrients. The Osorb-metal composites combine two advanced remediation materials: (1) a high-capacity organosilica sorbent, Osorb, and (2) reactive embedded metals. The composite materials absorb pollutants by removing them from the water and degrade the pollutants within the glass. The key technology developments to be achieved in Phase II include (1) formula optimization field testing with clients, (2) formulation performance improvements, and (3) development of commercial and modular bioretention packages. Compared to older bioretention systems, it is expected some of these systems will see orders-of-magnitude improvement in effective stormwater pollutant remediation and set new standards for best management practice. The broader impact/commercial potential of this project conducted by Dr. Yang and ABSMaterials will include: (1) providing an entirely new tool for resolving combined sewer overflow challenges with green infrastructure for dozens of cities, (2) substantial reduction of environmental pollution with lower treatment cost for contaminated stormwater, (3) improvement of aquatic and human health, and (4) facilitation of green stormwater reuse. The EPA and state governments are mandating many stormwater programs control non-point-source/CSO pollution. The tools for runoff treatment are often lacking to meet stricter regulations. Developing economical and effective Osorb-based stormwater solutions will substantially reduce negative effects of runoff pollutants on human and aquatic health. Seattle estimates economic impact of uncontrolled stormwater runoff at $113M and plans to build 12,000 bioretention systems to reduce urban runoff by 16,000,000 gallons annually. Other cities, including Cleveland, Philadelphia, Baltimore, and New York, are developing similar green infrastructure strategies. ABSMaterials is further developing an integrated curriculum for science courses at high schools and colleges and providing internships and training experiences involving advanced materials and water remediation. The company expects to create 6 new full-time positions working directly on the commercial activities during the period of this grant.
