The broader impact/commercial potential of this Small Business Innovation Research (SBIR) project results from the ability to design a reusable nanofiltration membrane platform for wastewater treatment. Energy-efficient and effective wastewater treatment for water purification and reuse remains a tremendous challenge because safe and reliable approaches are often capital and energy intensive. The production of clean water from wastewater for municipal or industrial reuse requires the removal of a wide range of organic and inorganic contaminants, including many hazardous and toxic substances (e.g., pesticides, heavy metals, pharmaceuticals, etc.). Energy costs are driven even higher by the high fouling propensity of polymeric membranes with the wide array of water contaminants. Preventing fouling and enabling high contaminant rejection with low energy requirements remain the two core challenges of membrane filtration for wastewater treatment. The proposed technology will address the two core challenges through the use of an anti-fouling surface chemistry. The low energy requirements, contaminant rejection, and anti-fouling properties of the proposed membrane make it a disruptive innovation that can easily penetrate the market, providing a cost-effective solution that is lacking in current membrane purification systems.This SBIR Phase I project proposes to develop a nanofiltration technology utilizing surface chemistry modification for the creation of an anti-fouling membrane for the rejection of pesticides. The United States spends nearly $9 billion a year on pesticides, which account for 16% of the world pesticide market. Out of the 25 most common active ingredients in pesticides, 76% are water soluble, which leads to contaminated soil, groundwater, and nearby bodies of water. The objectives of this project are to remove common commercial pesticides from water while investigating the advantageous effects of an anti-fouling membrane surface. Performance of the membrane will be investigated through cross flow filtration experiments to identify rejection, stability, and anti-fouling properties. The vision is to create a nanofiltration membrane with a broad contaminant rejection while decreasing energy requirements and fouling.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.

这项小型企业创新研究（SBIR）项目的更广泛的影响/商业潜力源于设计可重复使用的纳米滤膜平台用于废水处理。节能和有效的废水处理净水和再利用仍然是一个巨大的挑战，因为安全可靠的方法通常是资本和能源密集型的。从废水中生产用于市政或工业再利用的清水需要清除各种有机和无机污染物，包括许多危险和有毒物质（例如农药，重金属，药品等）。通过具有广泛的水污染物的聚合物膜的高结垢倾向，能源成本更高。 防止污染和能够对低能需求的高污染物排斥反应仍然是膜过滤的两个核心挑战。提出的技术将通过使用抗污染表面化学来应对这两个核心挑战。拟议膜的低能源需求，污染物的拒绝和反污染特性使其成为一种颠覆性的创新，可以轻松地穿透市场，提供了一种具有成本效益的解决方案，该解决方案在当前的膜纯化系统中缺乏，SBIR I阶段I阶段IS项目提议使用纳入表面化学的态度进行量身定制的纳入技术，以迎接量身像。 美国每年在农药上花费近90亿美元，占世界农药市场的16％。在农药中25种最常见的活性成分中，有76％的水溶性是水溶性，这会导致土壤，地下水和附近的水体。该项目的目标是从水中清除常见的商业农药，同时研究抗污染膜表面的有利作用。膜的性能将通过跨流过滤实验进行研究，以鉴定排斥，稳定性和抗污染特性。愿景是创建一个具有广泛污染物拒绝的纳米过滤膜的同时，同时减少了能量需求和污染。该奖项反映了NSF的法定任务，并被认为是通过基金会的知识分子优点和更广泛的影响来审查标准的评估值得支持的。
