Key Target Markets & Applications Can be used by water companies & utilities, health and environmental supervising & monitoring authorities, municipal water system authorities, hospitals, military bases, etc. Located at monitoring stations throughout the water distribution system, and coupled with CheckLights Portable Contamination Biomonitors (PCB-TOX), CheckLights CCBs enable an effective coverage of drinking water systems, together with the ability to pinpoint the boundaries of a contamination event, and trace contamination sources. Seamlessly integrated with other monitors and sensors as well as existing SCADA systems.
Key Features of CCB-TOX On line, continuous monitoring Highly sensitive Detects real toxicity Detection of a very broad range of contamination events Requires minimal operational intervention Easy installation, operation & maintenance No need for adjustments High overall system reliability Very fast detection & warning Minimal false positives & negatives Fully automated Remotely operated & controlled Very easy to use- no special skills required Easily integrated with other systems Suspicious samples are captured by an automatic sampler for further analysis
Benefits of CCB-TOX High reliability is ensured by the following built in features - automatic positive control tests; double check before alert signaling; automatic cleaning & flushing; once a month replacement of all biofouling-prone elements; minimal hands on. Low maintenance is ensured by the following built in features – quick and easy monthly cartridge replacement; automatic remote signaling of instrument malfunction.
Measuring principle: changes in the level of bacterial luminescence indicate potential toxicity in the sampled water. The CCB is connected to inlet water and clean reference water. It continuously (365/7/24) draws samples (at predetermined intervals) into two assay chambers. One is tested for the presence of cationic heavy metals and the other for organic toxicants. The light sensor records emitted luminescence and compares it to the level obtained in the reference reading. To minimize false alarms, once a toxicity state is noted (e.g. 50% luminescence decrease), a repeat reading is taken and then a repeat reference test. Should the result repeat itself, a toxicity alarm is turned on, and the suspected sample is drained into the grab sample container for future confirmation and analysis. Function
