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. ***

0123342 Raskin本研究的目的是开发和优化生物活性炭（BAC）过滤系统，以去除饮用水中低浓度的高氯酸盐。 这些系统必须生产出符合所有监管标准的水，具有生物稳定性，因此其质量在分配过程中不会降低，没有异味物质，并且具有低氯需求，因此不会形成过多的氯化副产物。 拟议的研究可能会导致一个有效的，实验室规模的高氯酸盐处理过程，可以产生满足这些要求的水。具体目标是：（1）开发用于BAC过滤器中微生物鉴定和定量的方法，（2）开发用于优化BAC过滤器操作和设计的生物膜建模方法，以及（3）整合工艺工程优化、微生物表征和生物膜建模。***
