Penetration of Chemical Disinfectants into Particles Developed in Water Treatment: Impact on the Biological Quality of Post-Disinfected Water

0072427 Loge本研究的目的是开发一种使用扫描共聚焦激光显微镜评估选定的化学消毒剂渗透到水处理过程中产生的颗粒中的方法。 实验方法的结果将与数学模型相结合，以产生一套直接适用于供水行业的准则，用于评估消毒后沃茨的生物质量。 本研究的动机是希望将重点从评估选定的病原体和指示生物的存活率作为消毒措施转移到基于颗粒的标准。 使用这种方法，所施用的消毒剂的剂量将基于悬浮液中颗粒的频率和分布。 大于临界粒度（定义为能够保护相关生物体免受所用消毒剂影响的最小颗粒）的所有颗粒将被视为同样能够携带一种或多种目标生物体。 将修改剂量以确保所施用消毒剂的特定渗透水平。***

0072427 Loge The objective of this research is to develop a method of assessing the penetration of selected chemical disinfectants into particles developed during water treatment using scanning confocal laser microscopy. Findings from the experimental approach will be coupled with a mathematical model to generate a set of guidelines directly applicable to the water industry for assessing the biological quality of post-disinfected waters. This research is motivated by the desire to shift the focus from evaluating the survival of selected pathogens and indicator organisms as a measure of disinfection to a particle-based standard. With this approach, the dose of the applied disinfectant would be based on the frequency and distribution of particles in suspension. All particles greater than a critical particle size (defined as the smallest particle capable of shielding an associated organism from the applied disinfectant) would be treated as being equally capable of harboring one of more targeted organisms of interest. The dose would be modified to insure a specified level of penetration of the applied disinfectant. ***
