| Abstract |
| The evaluation of microbial contamination in drinking water is a major concern worldwide. Adenosine triphosphate (ATP) monitoring can serve as a complement to the HPC method currently used for water quality tests because it offers rapid measurement, ease of use, and activity against microorganisms. In this study, we proposed an alternative to in situ rapid microbial monitoring methods. The ATP levels in tap water and surface-treated water were monitored using an online ATP analyzer. The ATP level of the surface-treated water was three times higher than that of the tap water. Furthermore, the correlation between E. coli and ATP confirmed that if the number of microorganisms in water is small, the ATP data must be obtained according to the target water characteristics to enable the monitoring for microbial viability in drinking water. For effective E. coli monitoring, online ATP data was stored in its own server database and an internet-of-things (IoT)-based microbial monitoring system was established and successfully applied. Recent advances in the ATP technology and IoT technology have enabled the quick and accurate online monitoring of the ATP level in water. This helps in maintaining the microbial stability of drinking water by detecting the signs of its microbial contamination early and to process it as quickly as possible. |
