Our LAR NitriTox™ toximeter analyzer continually monitors water treatment plants for pollutants. Potential toxins in water are determined through the reaction of highly sensitive bacteria. The measurements follow at intervals of less than 5 minutes. Thus, allowing enough time to introduce countermeasures after the occurrence of pollution. The NitriTox offers three warning levels, which can be individually set.

A failure within the nitrification not only leads to a breakdown of treatment processes but can cause an increased discharge of ammonia into rivers and lakes causing fish to die. The fast and reliable monitoring of incoming loads for toxicity warns of the danger in time, helping to protect the biological treatment processes. Additional pollution of public water and high discharge fees are prevented.  Some test methods that are available on the market can detect toxicity. They do not, however, identify exactly which toxins are present. By using fish, daphnia, molluscs, algae or luminous bacteria, they test whether a water sample has a toxic effect on the organisms.

NitriTox contains a bacteria culture (nitrifiers), which constantly and independently produces biomass. This means that there is enough bacteria at all times for each new measurement. As every water sample is tested with a fresh amount of bacteria, the risk of the fermenter being contaminated is removed. The bacteria are extremely sensitive to a multitude of toxins. Through their reaction to the harmful substances in the water sample, toxicity can be reliably determined. For example, with phenols a reaction already starts at a concentration of less than 0.10 mg/litre.
