Bacteria/Tryptophan Monitoring (BACTI-Station, BACTI-Wader)

 Chelsea Technologies Group (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 products. Both systems provide instant measurements of water-borne bacteria avoiding lengthy, potentially costly, delays in obtaining laboratory results.

Systems to choose from include:

BACTI Station BACTI-Station: 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 and logger. CTG’s UviLux fluorometers detect UV fluorescence with industry- leading sensitivity and selectivity and have been optimized 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-waderBACTI-Wader: 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.

Presentation given by James Sorensen, British Geological  Survey,  at the SWIG Health & Water Workshop (Jan 2018), outlining the use of  tryptophan-like fluorescence (TLF) to assess the microbial quality of drinking water - “Fluorescence for monitoring the microbial quality of drinking water”.

Academic Collaboration with the University of West of England

Dr Darren Reynolds, Associate Professor in Bio-Sensing Research at the University of the West of England is a recognized authority in the use of  fluorescence measurements for water quality monitoring, having published widely in this area for over a decade.  "For the past two years we have been collaborating very successfully with Dr Reynold’s group to both evaluate and optimize our UviLux fluorometers for bacteria monitoring and other applications in the water industry," reports Chelsea's Technical Director, Dr John Attridge.

Applications for the BACTI-Station & BACTI-Wader include:

  • Faecal Indicator (FI) monitoring
  • Assessment of bathing & shellfish waters
  • Filter bed management
  • Groundwater quality monitoring
  • Plant loading assessments from river abstractions
  • River pollution surveillance and investigative monitoring
  • Point source pollution surveys
  • Farm run-off detection and tracking
  • Groundwater quality monitoring
  • Combined Sewage Overflow (CSO) event detection
  • Bathing water quality monitoring
