0323963 Ergas The overall goal of this project is to assess the viability of anaerobic MBRs for treatment of domestic wastewaters for reclamation applications. Specific objectives include: (1) characterization of soluble COD in anaerobic MBRs treating low strength wastewaters, (2) evaluation of the effect of system operating conditions on effluent COD and membrane fouling and (3) evaluation of anaerobic MBR for pathogen removal and reclamation applications. The research will be accomplished through collaboration between U.S. and Mexican research laboratories with expertise in anaerobic treatment processes, MBR technology and pathogen removal. The U.S. team will conduct bench scale anaerobic MBR studies under controlled operating conditions (SRT, MLSS, COD loading rate) using synthetic, raw and settled wastewater. Studies will focus on how the presence of a membrane separation system affect the characteristics (VFA concentrations, MW distribution, biodegradability) of anaerobic effluents and what operating conditions, membrane materials and configurations minimize effluent soluble COD and maximize flux. The Mexican team will conduct pilot scale anaerobic MBR studies, focusing on pathogen removal and water reclamation applications.

[0323963]本项目的总体目标是评估厌氧mbr处理生活污水的可行性。具体目标包括：(1)厌氧MBR处理低强度废水时可溶性COD的表征；(2)评价系统运行条件对出水COD和膜污染的影响；(3)评价厌氧MBR去除病原体和回收应用的效果。这项研究将通过美国和墨西哥研究实验室在厌氧处理工艺、MBR技术和病原体去除方面的专业知识的合作来完成。美国团队将在可控的操作条件（SRT、MLSS、COD负荷率）下，使用合成废水、原始废水和沉淀废水进行实验规模的厌氧MBR研究。研究将集中在膜分离系统的存在如何影响厌氧废水的特性（VFA浓度、MW分布、生物降解性），以及什么样的操作条件、膜材料和配置可以最大限度地减少出水可溶性COD和最大通量。墨西哥团队将进行中试规模的厌氧MBR研究，重点是去除病原体和水回收应用。
