0422898 SungDescription: This project supports a cooperative project by Dr. Shih-Wu Sung, Department of Civil and Construction Engineering at Iowa State University (ISU), Ames, Iowa and Dr. Aysenur Ugurlu, Department of Environmental Engineering, Hacettepe University (HU), Ankara, Turkey. They plan to study the use of anaerobic membrane bioreactor (AMBR) in wastewater treatment. The goals are to develop an AMBR system for efficient treatment of low to medium strength wastewater, and to investigate the fouling mechanism and microbial community under a long solids retention time. Anaerobic process for wastewater treatment has several benefits. However, high biomass concentration, and long hydraulic and solids retention times are required for efficient anaerobic treatment due to the low biomass growth. Besides, the effluent quality of the anaerobic effluent is poorer than that of the aerobic treatment. These barriers have limited the wide applications of anaerobic process for the treatment of low strength wastewater. In this respect, membrane separation is an attractive option. However, membrane technology is highly energy intensive process, and the membrane fouling associated with anaerobic process is another issue yet to be resolved. Most importantly, the economy of membrane process is governed by cost of the membrane per se. In this study, the PIs will use non-woven fabric material, a waste material from a fabric industry, to optimize the operational parameters. The AMBR at ISU will be operated using non-woven filter materials while HU will test several commercial membrane modules including tubular and flat type microfiltration. Identical lab-scale AMBRs will be developed at both institutes. The PIs will evaluate optimal operating condition, especially for fouling control in the two studies. The results will be compared and an economic evaluation will be carried out. The project encompasses the skills and experience of respective nation's leading researchers in the areas of anaerobic process. These broader horizons and cross-linkage between ISU and HU researchers represent a synergistic approach to complement the holistic efforts in developing and advancing AMBR process that aims to contribute a new knowledge in environmental engineering. Scope and broader impact: The project will help to establish a new research area at ISU, which can be used for training undergraduate students for their final year projects. Additionally, summer high school interns will be encouraged to work closely with the graduate student in the AMBR project. A website will be developed within the university portal to disseminate the AMBR research to the students and the public. Through workshops and seminars, the outcomes of this research work will be disseminated to the U.S. environmental engineering communities. The results will benefit both the US and Turkey in developing a long-term research partnership and technology transfer. In the long term, the AMBR research will improve the environmental quality of nation's water bodies.

0422898 SUNGDESCRIPTION：该项目支持爱荷华州立大学（ISU）的民用与建筑工程系Shih-Wu Sung博士，爱荷华州，爱荷华州，爱荷华州和Aysenur ugurlu博士，Hacettepe University（Hu），Ankara，Ankara，Turkey。 他们计划研究厌氧膜生物反应器（AMBR）在废水处理中的使用。 目标是开发一个AMBR系统，以有效地处理低至中等强度废水，并在长期的固体保留时间下研究结垢机制和微生物群落。 废水处理的厌氧过程有几个好处。但是，由于生物量较低，需要高生物质浓度以及长液压和固体保留时间才能有效地厌氧治疗。此外，厌氧废水的废水质量比有氧治疗的废水差。 这些障碍限制了厌氧过程在低强度废水治疗中的广泛应用。 在这方面，膜分离是一个有吸引力的选择。 但是，膜技术是高能量密集型过程，与厌氧过程相关的膜结垢是尚未解决的另一个问题。最重要的是，膜过程的经济由膜本身的成本支配。 在这项研究中，PI将使用非编织面料材料，一种来自织物行业的废料，以优化操作参数。 ISU的AMBR将使用非编织过滤材料进行操作，而HU将测试几个商业膜模块，包括管状和扁平型微滤。 两家机构将开发相同的实验室规模的AMBR。 PI将评估最佳操作条件，尤其是在两项研究中用于结垢控制。结果将进行比较，并将进行经济评估。 该项目涵盖了各个国家领先的研究人员在厌氧过程领域的技能和经验。 ISU和HU研究人员之间的这些更广泛的视野和交叉链接代表了一种协同的方法，可以补充开发和推进AMBR进程的整体努力，旨在为环境工程提供新知识。 范围和更广泛的影响：该项目将有助于在ISU建立一个新的研究领域，该领域可用于培训本科生的最后一年项目。此外，将鼓励夏季高中实习生与AMBR项目的研究生紧密合作。 大学门户网站将开发一个网站，以向学生和公众传播AMBR研究。通过研讨会和研讨会，这项研究工作的结果将被传播给美国环境工程社区。 结果将使美国和土耳其在建立长期研究伙伴关系和技术转移方面受益。 从长远来看，AMBR研究将改善国家水体的环境质量。
