Algae and Toxicity Monitoring of Water Supplies
Product/Service Name
Equipment for Algae Monitoring and Toxicity Monitoring
TSE supply and support a range of highly sensitive instruments that can monitor water supplies in real time, both for online applications and in-situ measurements, giving early warning of potential hazards. The instruments fall into two main categories – Algae Monitoring, and Toxicity Monitoring.
Algae Monitoring
- Made possible using the cutting edge spectra fluorometers with algae class differentiation, detecting green algae, blue-green algae, diatoms, and cryptophytae simultaneously.
- They also measure yellow substances in the water, and compensate for these, which improves the accuracy.
- Instruments are available for the Lab, online for continuous algae measurements, and for in situ algae measurements, directly in the water.
- The results of all the fluorometers are highly accurate, and comparable to wet chemical and HPLC methods.
Toxicity Monitoring
- Made possible using the highly developed toximeters.
- With the aid of different organisms – daphnia, algae and fish – the instruments can detect toxins in real time.
- Although analytical methods in sensitivity have drastically improved, for toxicity detection the use of biological systems is inevitable.
- Here, model organisms act as reliable indicators for harmful agents, e.g. toxins.
- Toxicity tests are mainly based on the survival of organisms in the presence of test material. Static tests permanently expose the organisms to a series of dilutions over 24 or 48 hours.
- Dynamic tests, in contrast, shorten the test procedure and allow continuous monitoring.
- The registration of complex behaviour further reduces the response time for alarm evaluation.
The difficulty with most of the current biological systems is the restrictions imposed on testing toxins on animals. For fish based toximeters, the restrictions prevent the ability to study the behaviour of fish in the presence of various toxins.
bbe moldaenke have solved this problem by developing the Daphnia Toximeter. Because there are no restrictions for testing on these organisms, there have been many studies done and much data available on the types of toxins that can effectively be detected.
