The broader impact/commercial potential of this Small Business Technology Transfer (STTR) Phase I project is to provide a novel and cost-effective technology to remove NORM (Naturally Occurring Radioactive Materials) from the wastewater produced by fracking. The proposed research is of fundamental and practical significance to the area of produced water treatment. The proposed approach seeks to remove 99% of NORM from produced waters effectively, an important advance for environmental treatment. This approach also is expected to reduce the cost of the treatment technology and the associated impact on cost per barrel of gas and oil. This STTR Phase I project proposes to verify the effectiveness of new adsorbents waste water clean-up associated with fracking. The geologic formations containing oil and gas deposits contain Naturally Occurring Radionuclide Materials, referred to as NORM. Oil and gas fracking brings NORM to the surface in a concentrated form, posing a radiation safety hazard. There is currently no commercial product on the market to remove NORM from concentrated produced and flow back water selectively. By developing theory and computational methods with the Group Contribution method (GCM) and a novel optimization-based Computer-Aided Molecular Design (CAMD) framework, the teams seeks to generate better clay-based adsorbents than are currently commercially available for removal of produced water impurities. The modeling results need to be verified experimentally by synthesizing thenew adsorbents and comparing their adsorption behavior to the theoretically-predicted isotherms before commercializing them. The research may result in efficient and cost-effective adsorbents customized for the type of water contamination encountered using the new CAMD frameworks and cutting-edge experiments.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.

这一小型企业技术转移（STTR）I期项目的更广泛的影响/商业潜力是提供一种新颖且具有成本效益的技术，以从压裂产生的废水中清除规范（自然存在的放射性材料）。拟议的研究对产生的水处理区域具有基本和实际意义。拟议的方法旨在有效地从生产的水中清除99％的规范，这是环境治疗的重要进步。预计这种方法还将降低治疗技术的成本以及对每桶天然气和石油成本的相关影响。该STTR I阶段项目建议验证与压裂相关的新吸附剂废水清理的有效性。包含石油和天然气沉积物的地质地层包含天然存在的放射性核素材料，称为规范。 石油和天然气压裂以浓缩形式将标准带到表面，并带来辐射安全隐患。目前，市场上没有商业产品可以选择性地从浓缩产生和回流水中清除标准。 通过使用小组贡献方法（GCM）开发理论和计算方法，以及一种新型的基于优化的计算机辅助分子设计（CAMD）框架，这些团队试图产生比目前可用于清除生产的水杂质的商业可用的更好的基于粘土的吸附剂。需要通过合成当时的吸附剂并将其吸附行为与理论上预测的等温线进行比较，然后将它们的吸附行为与理论上预测的等温线进行比较，以实验验证建模结果。 这项研究可能导致有效且具有成本效益的吸附剂针对使用新的CAMD框架和尖端实验遇到的水污染类型进行定制。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优点和更广泛影响的审查标准来通过评估来支持的。
