On-site generation of mixed oxidants may reduce the formation of Total Trihalomethanes (TTHM) and Haloacetic Acids (HAA5) to acceptable levels for compliance with the US EPA Stage 1 Disinfectants and Disinfection By-Product Rule (DBPR). Superior disinfection efficacy and disinfection by-product (...
本幻灯片演示概述了一项关于TTHM和HAA5建模以及全面配电系统改进规划的研究.目标包括:进行TTHM和HAA5建模\n基于校准的水力模型\n确定可能存在高消毒副产物(DBP)的位置\n水平;和\n评估替代改进计划\n用于确定水力和水质\n缺陷.实现相关目标:开发校准的水力模型;改善水力不足;校准水质模型;改善水质缺陷;改进规划;以及...
The results of independent t -test indicated that the seasonal (spring and summer) difference was statistically significant in the case of temperature and TTHM ( p <0.05). Furthermore, total HAA 5 ≤60g/L and THM ≤100g/L in all the considered cities over the period of the study. The ...
检查8个工厂的数据\n在成品水中最高和最低平均TOC浓度的情况下,未显示任何组\n与配电系统中TTHM或HAA5水平的关系.\n三座污水处理厂\n经过详细研究,所有这些都能够提高通过工厂的TOC去除率,这是因为提高了效率\n凝固强化的凝血过程降低了TTHM水平,但没有降低HAA5水平.\n总的来说,这项研究没有发现可以用来预测...
The most dramatic difference in performance was with TTHM removal; the reagglomerated product treated double the water volume before reaching saturation for TTHM's, and the direct activated GAC exhibited what is known as "rollover" - the desorption of TTHM (probably due to adsorption of other, ...
Impact of Chlorine Dioxide-only and Combined Chlorine Dioxide/Free Chlorine Application on TTHM/HAA-5 Formationdoi:AWWA WQTC71467本研究的总体目标是描述ClO2-单独和联合的影响\nClO2/Cl2预氧化过程对模拟分布中总三卤甲烷(TTHM)和卤乙酸(HAA-5)生成的影响\n适用于各种原水质量的系统.合并过程的具体目标如下...
