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，旨在支持研究研究微孔膜生物反应器可能使用含有过度浓度硝酸盐的水的氢化性硝基化。 该膜用于支持能够氧化氢并实现反硝化的微生物种群，增加了完成氢的传质的速率，并起作用以将活性微生物培养物与所处理水分开。该项目的目标是研究控制氢和硝酸盐传质向微生物培养的因素，以确定硝化率和过程对水质的影响。 预计这项研究的结果将为基于膜的水的氢和硝酸盐传质和生物降解的数学模型的校准提供基础，以治疗水，以将硝酸盐的浓度降低至可接受的水平。 这些模型又被期望为确定基于该概念的工程在工程设计中的潜在应用提供基础，以解决硝酸盐污染地面和地表水的污染。 ***
