项目摘要

The broader impact/commercial potential of this I-Corps project is the development of environmentally friendly antimicrobial porous media. Current methods of controlling microbes, especially bacterial levels in industrial process waters such as HVAC and e-coating of vehicles, result in significant dispersal of chemical biocides and low rates of water recycling. Another area of concern is stormwater where large surges of flow are commonly not treated. As a result, recreational waterways can become impaired and beaches closed due to microbial contamination. Development of methods consuming minimal chemicals and energy can potentially improve industrial process efficiency, resulting in significant savings due to lower water and biocide consumption, with the further benefit of reducing the exposure of workers and the downstream environment to these toxic chemicals. In stormwater applications, the inexpensive media can be coupled to existing sediment removal systems where gravity enables treatment.This I-Corps project explores translation of a high-permeability durable porous media where biocides are affixed rather than released, enabling significant reductions in microbial loads. A novel technology can incorporate biocides into marine coatings, and, through chemical modification, at the surface of plastics. Such materials may significantly reduce microbial concentrations through lysing of bacteria present in water streams during passage through the media. The treatment occurs rapidly, with only seconds of exposure to the media required, while high levels of antimicrobial performance remain even after large volumes (e.g., tens of thousands of pore-volumes) of water are flushed through the media.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 I-Corps 项目更广泛的影响/商业潜力是开发环境友好型抗菌多孔介质。目前控制微生物的方法，特别是工业生产用水（例如暖通空调和车辆电泳漆）中的细菌水平，导致化学杀菌剂的大量扩散和水回收率低。另一个值得关注的领域是雨水，其中大量的水流通常没有得到处理。因此，休闲水道可能会受到损害，海滩也会因微生物污染而关闭。开发消耗最少化学品和能源的方法可以潜在地提高工业过程效率，由于水和杀菌剂消耗量减少而显着节省，并进一步减少工人和下游环境对这些有毒化学品的接触。在雨水应用中，廉价的介质可以与现有的沉积物清除系统相结合，通过重力进行处理。I-Corps 项目探索了高渗透性耐用多孔介质的转化，其中杀菌剂被固定而不是释放，从而显着减少微生物负荷。一项新技术可以将杀菌剂掺入海洋涂料中，并通过化学改性掺入塑料表面。此类材料可以通过在通过介质期间溶解水流中存在的细菌来显着降低微生物浓度。处理发生迅速，只需接触介质几秒钟，即使在大量（例如，数万个孔隙体积）的水冲过介质后，仍能保持高水平的抗菌性能。该奖项反映了 NSF 的法定标准使命，并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，被认为值得支持。
