9360331 Higgins The objective of this project is to evaluate a physical wastewater treatment process applicable to such waste streams; namely, crossflow ultrafiltration (UF) using novel ceramic membranes that are treated to have low-surface-free-energy, "non- fouling" surfaces. Processing of metastable oil-in-water emulsions with conventional UF membranes leads to rapid membrane fouling and flux decline and is generally uneconomic because of this problem. Ceramic UF membranes with modified, low-energy surfaces will be evaluated using low-cost, high-surface-area supports. The resulting membrane modules will be evaluated for filtration properties using different types of synthetic metastable oil-in-water emulsions. The objectives of these experiments will be definition of preferred membrane modification techniques and demonstration of the capability of surface- modified membranes to maintain high, stable permeate flux levels while producing a substantially hydrocarbon-free permeate. This is a Phase I award based on a proposal submitted in response to NSF 93-18, Small Business Innovation Research (SBIR) Program Solicitation, addresses a class of wastewaters, metastable oil/water emulsions and similar waste streams for which a need exists for more cost-effective treatment and for which the flows on a national scale are large. Current treatment technologies for metastable oil/water emulsions are often ineffective, and substantial impairment of water resources results from disposal of such inadequately treated waste streams. The membranes to be evaluated, if developed and integrated within a production scale membrane module would be the key element in an oily wastewater treatment system with low capital and operating costs. Applications for this technology include those with extremely high waste flows, such as produced water from oil wells and desalter bottoms from crude oil washing at refineries.

9360331希金斯该项目的目的是评估适用于此类废物流的物理废水处理过程； 也就是说，使用新型陶瓷膜的跨流超滤（UF）被视为具有低表面的“非结实”表面。 用常规的UF膜处理亚稳定的水中乳液会导致膜结垢和通量下降，并且由于这个问题而通常是不经济的。 将使用低成本，高表面区域的支撑物评估具有改良，低能表面的陶瓷UF膜。 将使用不同类型的合成稳态油内乳液评估所得的膜模块的过滤特性。 这些实验的目标将是首选的膜修饰技术的定义，并证明了表面修饰的膜保持较高，稳定的渗透通量水平的能力，同时产生基本的无碳氢化合物渗透率。 这是根据针对NSF 93-18（小型企业创新研究（SBIR）计划招标提交的提案）提出的提案的I阶段奖项，该奖项旨在解决一类废水，可稳态的油/水乳液和类似的废物流，以及对这些浪费的类似的废物流，对这些废水/水平的含量更高，并且在国家规模上有更大的成本效益治疗以及流动量很大。 当前用于亚稳态油/水乳液的治疗技术通常是无效的，并且水资源的大量损害是由于处理这种不充分处理的废物流而导致的。 如果在生产规模模块中开发并集成在生产规模模块中，则需要评估的膜将是低资本和运营成本的油性废水处理系统中的关键要素。 该技术的应用包括具有极高废物流量的那些，例如在炼油厂用原油洗涤的油井产生的水和干燥的底部水。
