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.

这个i-Corps项目的更广泛的影响/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，特别是工业过程水中的细菌水平，如暖通空调和车辆的电子涂层，导致化学杀生剂大量扩散，水循环利用率低。另一个令人担忧的领域是暴雨，那里的大流量通常得不到处理。因此，由于微生物污染，娱乐水道可能会受损，海滩可能会关闭。开发消耗最少的化学品和能源的方法可以潜在地提高工业过程的效率，由于减少了水和杀菌剂的消耗，从而大大节省了成本，并进一步减少了工人和下游环境对这些有毒化学品的暴露。在雨水应用中，这种廉价的介质可以与现有的重力处理沉积物去除系统相结合。这个i-Corps项目探索了一种高渗透性耐用多孔介质的转换，在这种介质中，生物剂被粘贴而不是释放，从而显著减少了微生物负载。一项新技术可以在海洋涂料中加入杀菌剂，并通过化学修饰在塑料表面加入杀菌剂。这种材料可以通过裂解流经介质的水流中存在的细菌来显著降低微生物浓度。治疗过程迅速，只需要几秒钟的接触媒体，而即使在大量(例如，数万个孔隙体积)的水通过媒体冲洗后，高水平的抗菌性能仍然存在。这一奖项反映了NSF的法定使命，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。
