L'EAU, L'INDUSTRIE, LES NUISANCES: "MEASUREMENT OF BACTERIAL SURFACE WATER QUALITY USING THE FLUIDION ALERT SYSTEM" (2017)
A scientific article from Fluidion, in collaboration with the SIAAP (Paris wastewater agency), published in the EIN magazine N°399, p. 81-87 (2017), focuses on the validation of the ALERT technology for microbiological monitoring in surface fresh waters and presents laboratory trials using Seine River samples.
Validation of the ALERT technology for bacterial quantification on the Seine water matrix
Key points:
- The ALERT System was recalibrated on the Seine water matrix to obtain results more representative of E.coli concentrations in the real environment. This new calibration showed that appearance of fluorescence is detected earlier than with the initial calibration previously established in the laboratory.
- The metrological performance of the ALERT System was evaluated by comparing its results with those of two accredited laboratories on 210 Seine water samples. The study showed that the results of the ALERT system were in agreement with the reference measurements (linear correlation coefficient of 0.932), with 97% of the measurements differing by less than a factor of 5.
- The ALERT System's measurement method shows intrinsic consistency comparable to the MPN reference method used by accredited laboratories, with high correlation coefficients over a full E.coli concentration range and a concentration range below 2,500 MPN/100mL, more representative of the bathing problem.
