Efficacy of disinfectant residualon microbial intrusion: A review of experiments
In order to determine the effectiveness of a disinfectant residual in the event of accidental microbial intrusion, a literature review was conducted of numerous studies, specifically investigating the fate of microorganisms introduced into experimental systems (laboratory‐, pilot‐, and isolated full‐scale). In these experiments, various types of microorganisms (including pathogens) were monitored in the presence or absence of a disinfectant residual. Monitoring of the organisms was performed in the bulk water and/or the biofilm. This review uncovered discrepancies in the findings obtained from laboratory‐ and pilot‐scale settings regarding the persistence of microorganisms in biofilm following an intrusion occurrence. However, by extrapolating the findings of the experimental systems, the most critical conditions with respect to microorganism persistence in a water system were identified: intrusion/inoculation taking place under zero‐ or low‐flow conditions and/or delay between the time of intrusion/inoculation and the onset of disinfection.
