U.S.-Turkey Cooperative Research: Application of Anaerobic Membrane Bioreactor (AMBR) for Wastewater Treatment

项目描述：本项目支持由爱荷华州艾姆斯爱荷华州立大学（ISU）土木与建筑工程系宋世武博士和土耳其安卡拉Hacettepe大学（HU）环境工程系Aysenur Ugurlu博士合作的项目。他们计划研究厌氧膜生物反应器（AMBR）在废水处理中的应用。目标是开发一种高效处理中低强度废水的AMBR系统，并研究长固体滞留时间下的污染机理和微生物群落。厌氧处理废水有几个优点。然而，由于生物质生长缓慢，高效的厌氧处理需要高的生物质浓度和长时间的水力和固体滞留时间。厌氧出水水质较好氧处理差。这些障碍限制了厌氧工艺处理低强度废水的广泛应用。在这方面，膜分离是一个有吸引力的选择。然而，膜技术是一个高能耗的过程，与厌氧过程相关的膜污染是另一个有待解决的问题。最重要的是，膜工艺的经济性是由膜本身的成本决定的。在本研究中，pi将使用非织造布材料，一种来自织物工业的废料，来优化操作参数。ISU的AMBR将使用无纺布过滤材料，而HU将测试几种商用膜模块，包括管式和平板式微过滤。这两个研究所将开发相同的实验室规模的ambr。在两项研究中，pi将评估最佳操作条件，特别是污垢控制。将对结果进行比较，并进行经济评估。该项目包括各自国家在厌氧过程领域的领先研究人员的技能和经验。ISU和HU研究人员之间的这些更广阔的视野和交叉联系代表了一种协同方法，以补充开发和推进AMBR过程的整体努力，旨在为环境工程贡献新知识。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，可用于培养本科生的最后一年的项目。此外，鼓励暑期高中实习生在AMBR项目中与研究生密切合作。将在大学门户网站内建立一个网站，向学生和公众传播AMBR研究。通过讲习班和研讨会，这项研究工作的成果将传播到美国环境工程界。研究结果将有利于美国和土耳其发展长期的研究伙伴关系和技术转让。从长远来看，AMBR的研究将改善国家水体的环境质量。

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.
