The broader impact/commercial potential of this Small Business Innovative Research (SBIR) project arises from addressing one of the world's major challenges - the need for water. We address this problem through the development of a novel technology for economic desalting for inexpensive clean water generation and the treatment of high concentration saline waste. There is no "one size fits all" approach to water desalting. Many factors such as salt concentration, the presence of specific ions, energy cost, pretreatment requirements and capital investments are important considerations in selecting a desalting technology. The carbon nanotube immobilized membrane distillation (CNIM-MD) being developed here offers many advantages such as the ability to utilize waste heat and solar energy and as well as the ability to handle high salt concentrations. The CNIM-MD is being designed with the aim of treating high salinity water (above 750,000 ppm dissolved solids that are not normally handled by reverse osmosis (RO). The primary target market for CNIM-MD is concentrating brine for zero liquid discharge (ZLD) where brine is concentrated and the solids are eventually precipitated out, pure water is reused and no water is discharged as industrial effluents. Other potential markets for CNIM-MD are treating RO reject to increase pure water yield, and the treatment of produced water in oil and gas industry.This SBIR Phase II project proposes to scale up the CNIM fabrication process via roll-to-roll (R2R) coating, demonstrate CNIM-MD at pilot scale and initiate commercial sales. The intellectual merit of the project lies in the novel approach to design and synthesis of scalable membrane systems for water desalination, and the treatment of saline waste. The CAPEX and OPEX of CNIM-MD compared to thermal evaporators is compelling, and CNIM-MD can be a major component of a hybrid ZLD treatment train integrating membrane technology with thermal evaporator. In short, the development of CNIM-MD will be a major development in the area of membrane treatment of high concertation brine. The success in the synthesis of novel membrane architecture such as CNIM will impact in many areas beyond desalination, which include carbon capture, gas purification, emission control, dehumidification as well as capturing pure water from the atmosphere. They have potential to impact major industries such as power plants, petrochemicals, oil and gas exploration, dehumidification, air purification, and food processing.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/商业潜力来自于解决世界上主要的挑战之一 - 对水的需求。我们通过开发一种新技术来解决这个问题，用于廉价清洁水的经济脱水和高浓度盐水废物的处理。没有“一件尺寸适合所有尺寸”的方法。诸如盐浓度，特定离子的存在，能源成本，预处理要求和资本投资等许多因素是选择脱盐技术的重要考虑因素。此处开发的碳纳米管固定膜蒸馏（CNIM-MD）提供了许多优势，例如使用废热和太阳能以及处理高盐浓度的能力。 CNIM-MD的设计目的是治疗高盐度​​水（超过750,000 ppm的溶解固体，这些固体通常不会通过反渗透（RO）处理。CNIM-MD的主要目标市场是零液体液体液体排放（ZLD）集中盐水（ZLD），在该盐水（ZLD）中，盐水被浓缩并最终降低了纯水，而纯净水则是纯净的，纯净水是不合时宜的。 CNIM-MD正在治疗RO拒绝以增加纯净水产量，并在石油和天然气行业中产生的水的处理。这二级项目提议通过卷到滚动（R2R）涂层来扩大CNIM制造过程，证明了CNIM-MD在Pilot scale和启动商业销售中均具有较新的范围scor saliser scor scor scor scor scor scor scor scor scor scor scor scorner scorner scormants scorners scorners scormants scorners scormant。废物与热蒸发器相比，CNIM-MD的CAPEX和OPEX令人信服，CNIM-MD可以是混合ZLD处理列车与热蒸发器相结合的混合ZLD处理列车的主要组成部分。简而言之，CNIM-MD的发展将是膜处理高级盐水领域的主要发展。诸如CNIM等新型膜结构的合成中的成功将在许多脱盐的领域影响，包括碳捕获，气体净化，排放控制，除湿以及从大气中捕获纯净水。它们有可能影响主要行业，例如发电厂，石化，石油和天然气勘探，除湿，空气净化和食品加工。该奖项反映了NSF的法定任务，并被认为值得通过基金会的知识分子优点和更广泛的影响标准通过评估来进行评估。
