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.

这个小企业创新研究（SBIR）项目的更广泛的影响/商业潜力来自设计可重复使用的纳滤膜平台用于废水处理的能力。为水的净化和再利用而进行高能效和有效的废水处理仍然是一项巨大的挑战，因为安全可靠的方法往往是资本和能源密集型的。从废水中生产清洁水用于市政或工业再利用需要去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、药物等）。由于聚合物膜具有广泛的水污染物的高结垢倾向，能源成本甚至更高。 防止结垢和以低能量要求实现高污染物截留仍然是用于废水处理的膜过滤的两个核心挑战。拟议的技术将通过使用防污表面化学来解决两个核心挑战。该膜的低能耗、污染物截留和抗污染特性使其成为一种颠覆性创新，可以很容易地渗透到市场，提供了一种目前膜净化系统所缺乏的具有成本效益的解决方案。SBIR第一阶段项目提出开发一种利用表面化学改性的纳米过滤技术，用于创建抗污染膜，用于截留农药。 美国每年在农药上花费近90亿美元，占世界农药市场的16%。在农药中最常见的25种活性成分中，76%是水溶性的，这会导致土壤、地下水和附近水体受到污染。本项目的目标是从水中去除常见的商业农药，同时调查防污膜表面的有利影响。将通过错流过滤实验研究膜的性能，以确定截留率、稳定性和抗污染性能。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
