本powerpoint演示文稿首先介绍了使用快速小规模柱状试验（RSSCT）测量总有机碳（TOC）和颗粒活性炭（GAC）去除消毒副产物（DBP）前体的研究目标。方法包括收集水样:在55加仑桶中，每天一次 从24街、联合山和 瓦尔维斯塔水处理厂；使用沉淀水；样品通过10µm玻璃纤维滤筒进行预过滤。 此外，RSSCT采样和SDS测试包括以下内容: 在前3天内每12小时采集一次样本，然后在RSSCT试验期间每天采集一次样本； 监测参数为TOC、TDN和UV254；模拟配电系统（SDS）测试在20%， 40%、60%和80%的UV254突破；SDS保持72小时和120小时 残留0.5 ppm Cl₂。介绍了TOC突破的建模方法，以及建议和未来研究。

This powerpoint presentation begins by presenting study objectives of using rapid small-scale column tests (RSSCTs) to measure total organic carbon (TOC) and disinfection byproduct (DBP) precursor removal by granular activated carbon (GAC). Methods included the collection of water samples: in 55-gallon drums once per month for 8 months from 24th street, Union Hill and Val Vista Water Treatment Plant; using settled water; samples were pre-filtered through a 10 µm glass fiber filter cartridge. Also, RSSCT sampling and SDS testing included the following: collecting samples every 12 hours in the first 3 days and then once per day during RSSCT test; parameters monitored were TOC, TDN and UV254; simulated distribution system (SDS) test at 20%, 40%, 60% and 80% of UV254 breakthrough; and, 72 hours and 120 hours holding time for SDS to remain 0.5 ppm Cl₂ residual. The modeling approach of TOC breakthrough is presented, along with recommendations and future research.
