本powerpoint演示的目的是:展示实验室和现场的代表性结果 为评估氧化剂的作用而进行的研究 关于颗粒介质过滤器中的颗粒去除， 认识到生物学/光合活性的作用；和 介绍在现场开展的后续工作 Onondaga县水务局，包括 更换预氧化剂的意外后果。研究了四种氧化剂 臭氧 氯， 二氧化氯，以及 高锰酸钾。提供了现场研究的结果，以及实验室过滤研究和设计标准。 提供了Onondaga县水务局的案例研究。AwwaRF项目2725（使用氧化剂提高过滤器性能）的目标如下:确定在何种条件下可以使用氧化剂通过混凝和过滤来提高颗粒物的去除率；为了更好地理解氧化剂增强的机理 颗粒去除； 确定在什么条件下 发生制定设计和操作标准，以 促进氧化剂强化颗粒去除。

The objectives of this powerpoint presentation were: to present representative results from lab and field studies conducted to evaluate the effect of oxidants on particle removal in granular media filters, recognizing the role of biology/photosynthetic activity; and, to present follow-up work conducted at the Onondaga County Water Authority, including unintended consequences of switching pre-oxidants. The four oxidants studied were ozone, chlorine, chlorine dioxide, and potassium permanganate. Results of the field studies are provided, along with lab filtration studies and design criteria. A case study is provided of the Onondaga County Water Authority. The goals of the AwwaRF Project 2725, Using Oxidants to Enhance Filter Performance, are listed and include: to determine the conditions under which oxidants can be used to enhance the removal of particles by coagulation and filtration; to better understand the mechanisms of oxidant-enhanced particle removal; to determine the conditions under which it will occur; and, to develop design and operating criteria to promote oxidant-enhanced particle removal.
