United Utilities has chosen the Chelsea Technologies Group (CTG) ALGAE-Wader Pro and ALGAE-Station Pro systems to assist them in real time assessment of algae levels in their water sources feeding into a number of their Water Treatment Works.
The CTG Algae monitoring systems were chosen after an extended trial period which successfully demonstrated the use of the TriLux fluorometer, from which these systems are based, in detecting chl-a, Phycocyanin and Phycoerythrin levels.
The CTG ALGAE-Wader Pro is a portable system which includes the Hawk handheld display and logger. The Hawk provides simple and robust interaction with the field operator, displays all data in either numerical or graphical form, provides RAG thresholds and logs all data with both time and position stamps.
The CTG ALGAE-Station Pro is a robust wall mounted system which includes the Watchkeeper display and logger. The Watchkeeper displays and logs all data, provides Alarm thresholds and outputs 4-20 mA for connection to SCADA type networks.
