The broader impact/commercial potential of this I-Corps project is to develop a one-step wastewater treatment technology to reduce energy requirements and the need for added chemicals. The global wastewater treatment market that is expected to cross $15 billion by 2025, driven by stringent government regulations. Key market segments include: breweries that use huge amounts of water (5-7 pints of fresh water per pint of beer produced); leachates from landfills that would contaminate fresh groundwater if not treated; and unconventional oil and gas drilling operations that used over 20 trillion gallons of fresh water for hydraulic fracturing in 2018. For on-site processing, whole wastewater treatment involves multiple steps including odor control, removal of macrobiotic solid matter (primary), anaerobic digestion that produces methane (secondary), removal of inorganics (tertiary), and addition of chlorine and sodium hypochlorite. The alternative is to discharge process water directly into the city sewer discharge system at a fee. The proposed project can achieve pure water extraction is one-step with small footprint. This I-Corps project is based on the development of a one-step wastewater treatment technology using a recyclable gas that reduces energy requirements and eliminates the need for added chemicals. The proof-of-concept study is completed in the laboratory, and an alpha-test unit is being built for field testing. Preliminary techno-economic analysis indicates that the process may reduce both the cost and space requirements by 70% over commercial processes.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/商业潜力是开发一步废水处理技术，以减少能源需求和对添加化学品的需求。在严格的政府法规的推动下，到2025年，全球废水处理市场预计将超过150亿美元。主要市场细分包括：使用大量水(每生产一品脱啤酒5-7品脱淡水)的啤酒厂；垃圾填埋场的渗滤液，如果不处理，将污染淡水地下水；以及非常规石油和天然气钻探作业，2018年使用了超过20万亿加仑的淡水进行水力压裂。对于现场处理，整个废水处理包括多个步骤，包括气味控制、去除微生物固体物质(初级)、产生甲烷的厌氧消化(次级)、去除无机物(次级)以及添加氯和次氯酸钠。另一种选择是收费将处理后的水直接排放到城市下水道排放系统中。该方案可实现纯水一步提取，占地面积小。这个i-Corps项目是基于使用可回收气体的一步废水处理技术的开发，该技术可以减少能源需求并消除对添加化学品的需要。概念验证研究已在实验室完成，并正在建造一个阿尔法测试单元，用于现场测试。初步的技术经济分析表明，与商业过程相比，该过程可以减少70%的成本和空间需求。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
