The Electron Beam Process in Drinking Water Treatment: Biological, Cryptosporidium and Giardia, Control and Contaminant Destruction

库珀97-29965这是一个奖项，旨在支持利用被激发的电子束产生的电离辐射对水进行消毒的研究。这项研究将集中在利用BEAM对隐孢子虫和贾第鞭毛虫进行灭活。它将考虑在使用传统的混凝、沉淀和过滤工艺处理原水之前，将BEAM用于处理原水的潜在用途。这项研究还将考虑在滤池反冲洗水返回到原水供应管道之前使用BEAM处理的可能性。由于在将水放入饮用水分配系统之前可能需要残留消毒剂，这项研究还将探讨电子束对氯等化学消毒剂产生的消毒副产物前体的潜在破坏作用。由于地表水和地下水供应中的许多常见污染物都是来自点源和非点源的有机化学品，研究还将研究光束用于销毁有机杀虫剂、除草剂和有机化合物的可能性，这些物质会对饮用水的味道和气味产生不利影响。该项目的结果有望为考虑将电子束辐射作为一种消毒受目标生物污染的水的方法提供潜在有用的信息。共同调查人员包括南佛罗里达大学海洋科学系教授Joan Rose博士、佛罗里达国际大学化学系副教授Kevin O‘Shea博士和圣母大学辐射实验室高级科学家Prashant V.Kamat博士。爱德华·H·布莱恩博士，环境工程项目主任1998年3月2日

Cooper 97-29965 This is an award to support research on a disinfection process for water by use of ionizing radiation produced by a beam of energized electrons. The research will focus on use of the beam for inactivation of Cryptosporidum sp and Giardia sp. It will consider the potential use of the beam for treatment of raw water prior to its treatment using conventional coagulation, sedimentation and filtration processes. The research will also consider the possibility of using the beam to treat filter backwash water prior to its return to the raw water supply line. Since it is likely that a residual disinfectant will be needed before placement of water into a potable water distribution system, this research will also address the potential the electron beam has for destruction of precursors of disinfection byproducts produced by chemical disinfectants such as chlorine. Since many of the common contaminants of surface and ground water supplies are organic chemicals originating from both point and non-point sources, the research will also examine the potential use of the beam for destruction of organic pesticides, herbicides and organic compounds that adversely affect the taste and odor of water destined for potable consumption. The results of this project are expected to provide information potentially useful in considering electron beam radiation as an approach to disinfection of water contaminated with the target organisms.
