9908906 Ergas This is an award to support research investigating the possible use of a microporous membrane bioreactor for hydrogenotrophic denitrification of water containing excessive concentrations of nitrates. The membrane serves to support the microbial population capable of oxidizing hydrogen and accomplishing denitrification, increases the rate at which mass transfer of hydrogen is accomplished and acts to separate the active microbial culture from the water being treated. Objectives of this project are to investigate the factors that control hydrogen and nitrate mass transfer to the microbial culture, to determine denitrification rates and impact of the process on water quality. Results of this research are expected to provide the basis for calibration of mathematical models of hydrogen and nitrate mass transfer and biodegradation in membrane-based processes for treatment of water to reduce concentrations of nitrate to acceptable levels. These models are in turn expected to provide the basis for determining the potential application of processes based on this concept in engineering design of systems that address nitrate contamination of ground and surface water. ***

9908906 Ergas这是一个奖项，以支持研究调查可能使用的微孔膜生物反应器的氢营养反硝化水含有过量浓度的硝酸盐。 膜用于支持能够氧化氢和完成脱氮的微生物种群，增加完成氢的传质的速率，并用于将活性微生物培养物与被处理的水分离。本项目的目标是调查控制氢气和硝酸盐质量转移到微生物培养物的因素，以确定反硝化速率和该过程对水质的影响。 这项研究的结果预计将提供校准的数学模型的氢和硝酸盐的传质和生物降解膜为基础的水处理过程中，以减少硝酸盐的浓度到可接受的水平的基础。 反过来，这些模型预计将提供基础，以确定潜在的应用程序的基础上，这一概念的系统，解决地下水和地表水的硝酸盐污染的工程设计。***
