The broader impact of this SBIR Phase II project is an affordable and sustainable solution for onsite water reuse. The need for better water efficiency and reuse technology is growing quickly. Driven by unsustainable water use and rapid population growth, groundwater aquifers across the United States and around the world are drying up as environmental change causes water scarcity and drought. For almost one billion people worldwide, water scarcity is life-threatening. This project will develop a natural water treatment system that cleans household greywater for safe reuse in the home and garden, reducing total household water consumption up to 40% and simultaneously providing an attractive outdoor plant amenity. The treatment system will use compact, modular containers that can be quickly deployed and easily scaled for any size home and anywhere water infrastructure is expensive, scarce, or compromised. The system will remotely monitor water quality and system performance to ensure safety and reliability. This project will develop a novel ecological treatment process that combines the biological systems of natural wetlands and the purifying properties of volcanic soils to clean and recycle household greywater for safe reuse in the home and garden. The system will use embedded sensors to remotely monitor water quality and system performance to ensure safety and reliability. The project tests a variety of plant species and natural substrates to maximize functional and aesthetic value and to improve tolerance to harsh climates and shade. Innovative management strategies, such as microbial inoculation and recirculating flow, will be tested to improve system health and treatment efficiency. This project will optimize treatment performance to meet regulatory standards. It will also assess improved treatment of common greywater contaminants such as toxic chemicals, heavy metals, cleaning products, fats, oils, grease, and urine. In addition to greywater treatment, alternative water treatment applications, such as nitrogen removal for rural septic systems and urban stormwater runoff, will be explored.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.

SBIR二期项目的更广泛影响是为现场水再利用提供了一种经济实惠且可持续的解决方案。对提高用水效率和再利用技术的需求正在迅速增长。在不可持续的用水和人口快速增长的驱动下，由于环境变化导致水资源短缺和干旱，美国和世界各地的地下水含水层正在枯竭。对于全世界近10亿人来说，水资源短缺威胁着他们的生命。该项目将开发一个天然水处理系统，清洁家庭灰水，在家庭和花园中安全再利用，减少家庭总用水量高达40%，同时提供一个有吸引力的户外植物设施。该处理系统将使用紧凑的模块化容器，可以快速部署并轻松扩展到任何大小的家庭和任何水基础设施昂贵，稀缺或受损的地方。该系统将远程监控水质和系统性能，以确保安全性和可靠性。该项目将开发一种新的生态处理工艺，结合自然湿地的生物系统和火山土壤的净化特性，清洁和回收家庭灰水，供家庭和花园安全再利用。该系统将使用嵌入式传感器远程监测水质和系统性能，以确保安全性和可靠性。该项目测试了各种植物物种和天然基质，以最大限度地提高功能和美学价值，并提高对恶劣气候和阴影的耐受性。创新的管理策略，如微生物接种和再循环流，将进行测试，以提高系统的健康和处理效率。该项目将优化处理性能，以满足监管标准。它还将评估改善对常见灰水污染物的处理，如有毒化学品、重金属、清洁产品、脂肪、油、油脂和尿液。除灰水处理外，还将探索其他水处理应用，如农村化粪池系统和城市雨水径流的脱氮。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。
