Wastewater Monitoring Solutions

Chelsea Technologies Group (CTG) supply a range of sensors for monitoring final effluent or process wastewater, holding lagoons or natural watercourses. We supply online, in situ or hand-held instruments for a range of different parameters.  CTG has addressed the challenges faced by laboratory managers, process scientists and engineers who wish to assess real-time levels of bacteria in water systems with the introduction of the following new products. Both systems provide instant measurements of water-borne bacteria avoiding lengthy, potentially costly, delays in obtaining laboratory results.


BACTI StationBACTI-Station & BACTI-Station Pro:  Provides real-time, highly sensitive measurements for assessing bacterial levels. The BACTI-Station comprises of a CTG UviLux fluorometer and a Watchkeeper wall mounted data display & logger. CTG’s UviLux fluorometers detect UV fluorescence with industry- leading sensitivity and have been optimised for minimal interference from water turbidity.  Data is displayed on the Watchkeeper’s colour touchscreen and is logged internally. Up to three 4 - 20mA outputs are provided for data transmission.


 BACTI-Wader & BACTI-Wader Pro:BACTI-Wader & BACTI-Wader Pro: Provides instant measurements of water-borne bacteria avoiding lengthy & potentially costly delays in obtaining laboratory results.  It allows surveyors and regulators to assess real-time, in situ levels of bacteria in water systems. This is achieved by detecting UV Tryptophan fluorescence, which has been shown to correlate with bacterial levels.
