本powerpoint演示文稿首先简要概述了卡茨基尔和特拉华水系统以及污垢试点研究目标，包括:检查套管污垢可能性，包括季节效应和预氯化的影响，氯滞留时间的影响，以及水化学（pH、氟化物）的影响；以及与 清洁频率。污垢试验研究布局包括3列，其中前两列是本演示的重点: 第1列-ITT/Wedeco LPHO（Spektrotherm灯）和 两个平行单元，单元A氯化；和 第2列-特洛伊MP，一个单元，氯化。介绍了试验研究运行总结以及运行参数。提供了运行影响以及试点结论:上游用次氯酸钠氯化 紫外线（UV）装置的污染增加；季节性水温影响污垢；更长的氯滞留时间可能会减少 污染势；以及添加氟化物和/或pH抑制 降低污垢的可能性。包括表格、数字。

This powerpoint presentation begins by providing a brief overview of the Catskill and Delaware Water System and the fouling pilot study objectives that included: examining the sleeve fouling potential including seasonal effects and the impact of pre-chlorination, the impact of chlorine detention time, and the impact of water chemistry (pH, fluoride); and, the operational impact related to cleaning frequency. The fouling pilot study layout included 3 trains, the first two of which are the focus of this presentation: Train 1 - ITT/Wedeco LPHO (Spektrotherm Lamps) and two parallel units, Unit A chlorinated; and, Train 2 - Trojan MP, one unit, chlorinated. A summary of pilot study runs is presented, along with operating parameters. The operational impact is provided along with pilot conclusions: chlorination with sodium hypochlorite upstream of the ultraviolet (UV) units increases fouling; seasonal water temperature impacts fouling; longer chlorine detention time may decrease fouling potential; and, addition of fluoride and/or pH suppression decreases fouling potential. Includes tables, figures.
