Online Water Toxicity Monitoring


Source: LAR Process Analysers AG

Monitoring of water toxicity is of special importance, especially when surface water or ground water are used for the preparation of drinking water. Since a variety of substances are harmful for human being reliable online monitoring is recommended.

LAR's online toxicity analyzer ToxAlarm continuously monitors drinking and surface water for toxic pollutants. This toximeter contains a highly sensitive bacteria culture, which constantly and independently produces biomass. This means that the risk of the test organisms within the analyzer being contaminated is avoided, as every water sample is tested with a small and fresh amount of bacteria. Unlike alternative toxicity tests, purchasing or time consuming breeding of test organisms is not necessary anymore. The used subset of nitrifiers is brought into contact with the waste water. Then, an oxygen electrode measures the bacteria's oxygen consumption, whereby the toxicity concentration can be detected. The measurement takes place in 5-10 min

LAR's ToxAlarm reliably detects harmful substances resulting from industrial discharges or environmental influences. It is suitable for online toxicity monitoring as well as for laboratory use. No more 'should haves, would haves, could haves'. ToxAlarm warns you within minutes.
