本powerpoint演示文稿首先提供了加利福尼亚州活橡树市的背景信息。给出了水井和砷含量的统计数据，以及1999年至2004年的历史砷含量和2005年的需水量。本文概述了去除技术以及以下主题:台架试验和RFP过程；审查台架试验结果；生命周期评价的回顾；此外，还将更新未来的试点项目，其中将启动试点，以确认试验结果和结果 确认关键设计参数 砷性能， Mn性能， 运维成本，以及 布局

This powerpoint presentation begins by providing background information on the City of Live Oak, California, water upgrades. Statistics on wells and arsenic levels are given, along with historic arsenic levels from 1999 to 2004, and water demand in 2005. Removal technologies are outlined along with topics that include: bench testing and RFP process; review of bench testing results; review of life cycle evaluation; and, an update on a future pilot program where piloting will be initiated to confirm bench results and confirm key design parameters for arsenic performance, Mn performance, O&M costs, and layout.
