Aqualog ® Datastream


Aqualog ® Datastream - for Instant Water Quality Reports

The NEW Aqualog® Datastream Dashboard facilitates completely automated analysis and reporting of a wide range of organic matter parameters that are critical for managing and optimizing the drinking water treatment process. The Datastream parameters have been selected to specifically target disinfection by-product issues, algal issues and other contamination components. The Dashboard provides the latest readings, time series and tables or trend analysis, % removals, thresholds and MCLs (Maximum Contaminant Limits) for all of these parameters, and reports on fit statistics and residual evaluation for system performance monitoring, contamination detection and early warning alerts.

The Datastream Dashboard is the latest enhancement to the HORIBA Aqualog. The Aqualog is the only instrument with patented simultaneous UV-Vis and fluorescence ExcitationEmission Matrices (EEMs), which are acquired up to 100 times faster than with other instruments.

Water treatment facilities can also upload their independent data to simultaneously analyze pH, alkalinity, turbidity, Cl2 and other key parameters.
