摘要

国家公用事业公司提供给家庭的饮用水质量差，以及印度城市部分地区对咸淡地下水资源的严重依赖，导致采用家庭水处理解决方案。目前唯一能够脱盐的家庭水处理解决方案是反渗透(RO)。然而，现有的RO产品只能回收25-50%的给水作为可用的产品水。在本研究中，设计了一种依赖电渗析(ED)的替代解决方案，并通过实验证明，该方案可实现80%的回收率，从3000 ppm的饲料盐度中产生12 L/h的水，所需盐度为350 ppm。我们还发现，拟议系统的成本和规模与现有的家庭RO系统相当。家庭ED水处理系统可以与现有的反渗透产品竞争，同时在水资源紧张的印度提供改善节水的优势。

Feasibility study of an electrodialysis system for in-home water desalination in urban India

Poor quality of drinking water delivered to homes by state utilities, and a large reliance on brackish ground water resources in parts of urban India, has resulted in the adoption of in-home water treatment solutions. The only existing in-home water treatment solution capable of desalination is reverse osmosis (RO). However, existing RO products can recover only 25–50% of the feed water supplied as usable product water. In this study, an alternative solution that relies on electrodialysis (ED) was designed and experimentally shown to achieve a recovery of 80%, producing 12 L/h of water at the desired salinity of 350 ppm from a feed salinity of 3000 ppm. The cost and size of the proposed system were also found to be comparable to existing in-home RO systems. In-home ED water treatment systems could compete with existing RO products while providing the advantage of improved water-conservation in water-stressed India.

期刊介绍： Development Engineering: The Journal of Engineering in Economic Development (Dev Eng) is an open access, interdisciplinary journal applying engineering and economic research to the problems of poverty. Published studies must present novel research motivated by a specific global development problem. The journal serves as a bridge between engineers, economists, and other scientists involved in research on human, social, and economic development. Specific topics include: • Engineering research in response to unique constraints imposed by poverty. • Assessment of pro-poor technology solutions, including field performance, consumer adoption, and end-user impacts. • Novel technologies or tools for measuring behavioral, economic, and social outcomes in low-resource settings. • Hypothesis-generating research that explores technology markets and the role of innovation in economic development. • Lessons from the field, especially null results from field trials and technical failure analyses. • Rigorous analysis of existing development "solutions" through an engineering or economic lens. Although the journal focuses on quantitative, scientific approaches, it is intended to be suitable for a wider audience of development practitioners and policy makers, with evidence that can be used to improve decision-making. It also will be useful for engineering and applied economics faculty who conduct research or teach in "technology for development."
