Collaborative Research: Anaerobic Membrane Bioreactors for Treatment and Reclamation of Domestic Wastewater

0323963 厄加斯 本项目的总体目标是评估厌氧MBR处理生活废水的可行性，以供填海应用。具体目标包括：（1）在处理低浓度废水的厌氧MBR中可溶性COD的表征，（2）系统操作条件对流出物COD和膜污染的影响的评估，和（3）用于病原体去除和回收应用的厌氧MBR的评估。这项研究将通过美国和墨西哥研究实验室之间的合作来完成，这些实验室在厌氧处理工艺，MBR技术和病原体去除方面具有专业知识。美国团队将在受控操作条件（SRT，MLSS，COD负荷率）下使用合成，原始和沉淀废水进行实验室规模的厌氧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），以及什么操作条件，膜材料和配置最大限度地减少废水可溶性COD和最大限度地提高通量。墨西哥团队将进行中试规模的厌氧MBR研究，重点是病原体去除和水回收应用。

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.
