本幻灯片演示的目的是确定颗粒活性炭（GAC）和游离氯在长期消毒副产品（DBP）监管合规性方面的最低成本应用，并 通过以下方式评估GAC的绩效: 中试规模和试验规模工作评估 GAC过滤器和吸附器 GAC过滤后吸附器。对过滤吸附器进行了中试 模拟生物去除机制和吸附。 对操作条件进行了评估，包括: GAC深度； 碳类型，沥青与褐煤； 空床接触时间（EBCT）；可生物降解有机碳；和 过滤操作、浊度和颗粒计数。包括表格，数字。

The objective of this slide presentation was to identify the least cost application of granular activated carbon (GAC) and free chlorine for long-term disinfection byproduct (DBP) regulatory compliance and to evaluate the performance of GAC through pilot scale and bench-scale work evaluating GAC filter adsorbers and GAC post-filter adsorbers. Pilot testing of filter adsorbers was conducted to simulate biological removal mechanisms as well as adsorption. Operating conditions were evaluated including: depth of GAC; carbon type, Bituminus vs. Lignite; empty bed contact time (EBCT); biodegradable organic carbon; and, filter operation, turbidity and particle count. Includes table, figures.
