*** Higgins 9501443 This Small Business Innovation Research Phase II project is aimed towards the development of improved methods of treating poorly stabilized (metastable) oil/water emulsions via ceramic crossflow filtration with membranes that are highly resistant to fouling and that have relatively low associated costs. The overall objectives of this program include: (a) development of a more comprehensive and fundamental understanding of membrane fouling processes inherent to crossflow filtration of produced waters and similar feed streams, and their dependence on creamic membrane properties, and (b) development of membranes on low-cost ceramic modules that are highly fouling-resistant. Experimental work will encompass modification and optimization of membrane fabrication approaches scouted in Phase I work, long-term crossflow process testing of membranes on both live and simulated oil/water emulsion streams, and thorough physical and chemical characterization of as-fabricated membranes, fouled membranes, and predominant foulant species. It is anticipated that useful knowledge related to membrane fouling mechanisms and their relationship with ceramic membrane characteristics will result from this program, in addition to commercially viable ceramic membranes that are highly fouling-resistant during metastable oil/water emulsion processing. The highly fouling-resistant membranes to be developed in this program will be readily scalable to industrial-scale low-cost ceramic modules, and should provide significant benefits in both the economy and effectiveness of metastable oil/water emulsion separations. These separations ecompass a wide range of very high volume wastewaters such as produced water from oil wells, desalter bottoms from crude oil washing, shipboard bilge and tank cleaning wastes, vehicle washwaters, and others.

***希金斯9501443这个小型企业创新研究阶段II阶段项目旨在开发改进的方法，方法是通过陶瓷跨流量过滤稳定稳定（可稳定的）油/水乳液，其膜具有高度抗性的熔膜，并且具有相对较低的相关成本。该程序的总体目标包括：（a）对膜结垢过程的更全面和基本的了解，对生产的水和类似饲料流的跨流量过滤固有的膜固有的过程，以及它们对乳脂膜性能的依赖，以及（b）在低成本陶瓷模块上开发膜的膜，这些模块极高地构造了fuouling-Fouling-isistant。实验工作将涵盖I阶段工作中搜索的膜制造方法的修改和优化，在活和模拟的油/水乳液流上对膜进行的长期跨流过程测试，以及彻底的物理和化学表征，使膜的物理和化学表征，构造的膜以及主要的污垢。可以预料，除了在在亚抗体/水乳液处理过程中具有高度结垢的耐药性，与膜结垢机制有关的有用知识及其与陶瓷膜特征的关系还将引起该程序。 该计划中要开发的高度结垢膜将很容易扩展到工业尺度的低成本陶瓷模块，并应为亚稳态油/水乳液分离的经济和有效性带来重大利益。这些分离的eCompass众多的大量废水，例如从油井产生的水，原油洗涤，船上舱底和坦克清洁废水，车辆洗手液等的底层底部。 关键字：陶瓷膜，油/水乳液，抗污染膜*** p：/sbir/yhashimi/9501443a.doc
