Process Optimization, Molecular Microbial Characterization, and Biofilm Modeling of a Bioreactor for Perchlorate Removal from Drinking Water

0123342拉斯金这项研究的目标是开发和优化生物活性碳过滤系统，以去除饮用水中低浓度的高氯酸盐。这些系统必须生产符合所有监管标准的水，具有生物稳定性，以便其质量在分配过程中不会退化，不含异味物质，并且氯需求量低，因此不会出现过量氯化副产物形成的问题。这项拟议的研究可能会产生一种高效的、实验室规模的高氯酸盐处理工艺，可以生产出满足这些要求的水。其具体目标是：(1)开发BAC滤池中微生物的鉴定和定量方法；(2)开发一种用于优化BAC滤池运行和设计的生物膜建模方法；(3)集成工艺工程优化、微生物表征和生物膜建模。***

0123342 Raskin The objective of this research is to develop and optimize biologically active carbon (BAC) filtration systems to remove low concentrations of perchlorate from drinking water. These systems must produce water that meets all regulatory standards, is biologically stable so that its quality does not degrade during distribution, is free of odorous substances, and has a low chlorine demand so that excessive chlorination by-product formation will not be an issue. The proposed research could result in an efficient, bench-scale perchlorate treatment process that can produce water meeting these requirements. The specific objectives are: (1) to develop methods for microbial identification and quantification in BAC filters, (2) to develop a biofilm modeling approach for optimizing BAC filter operation and design, and (3) to integrate process engineering optimization, microbial characterization and biofilm modeling. ***
