U.S.-Mexico Research: Pretreatment of Industrial Wastewater Streams for the Removal of Suspended Fine Particles and Dispersed Oil Droplets by Air-Sparged Hydrocyclone Flotation

这份美国-墨西哥奖将支持犹他大学Jan Miller博士和墨西哥Saltillo理工学院Jose Parga教授之间的合作研究项目。该项目的主要目的是演示气相旋流器（ASH）浮选技术在回收和分离美墨边境地区工业废水中悬浮细颗粒和分散油滴方面的技术性能。这项研究将包括对造成边境地区污染的各种工业废水流进行调查和取样，对样品进行特征分析，进行比较浮选试验，以及对灰化学物质进行优化的试验站研究。多年来，将未经处理的工业废水排放到跨界水域造成了美墨边境沿线的生态和美学退化、经济损失和对人类健康的威胁。未经处理的工业废水会严重降低常规处理设施对污水的有效处理能力。灰浮选技术是由犹他大学在过去十年中开发的，它将传统水力旋流器和泡沫浮选技术的优点结合到一个设备中。如果成功，该项目将有机会大大减少美墨边境地区工业废水流的污染，从而为两国带来重大的环境和健康效益。* * *

9413352 Miller This U.S.-Mexico award will support a collaborative research project between Dr. Jan Miller, University of Utah, and Professor Jose Parga, Instituto Tecnologico de Saltillo, Mexico. The project's main objective is to demonstrate the technical performance of the air-sparged hydrocyclone (ASH) flotation technology for the recovery and separation of suspended fine particles and dispersed oil droplets from industrial waste water streams along the U.S.-Mexico border region. The research will involve surveying and sampling various industrial waste water streams that contribute to the contamination of the border region, characterization of the samples, comparative flotation tests, and pilot station studies for ASH optimization. The discharge of untreated industrial waste water into transboundary waters has contributed to ecological and esthetic degradation, economic losses, and threats to human health along the U.S.-Mexico border for many years. Untreated industrial waste water can seriously degrade the ability of conventional treatment facilities to treat sewage effectively. The ASH flotation technology, developed by the University of Utah during the past decade, combines the advantages from both conventional hydrocyclone and froth flotation technologies into a single piece of equipment. If successful, the project will provide the opportunity to significantly reduce pollution from industrial waste water streams in the U.S.-Mexico border area, and provide, therefore, significant environmental and health benefits to both countries. ***
