LAR NitriTox

Online Toximeter that protects the biology of waste water treatment plants, especially the nitrification process.


LAR has developed an online method that considerably reduces cost, maintenance and operational expenditure: NitriTox. This measurement system contains a highly sensitive, self-regenerating bacteria culture, which can be continuously used to test the toxicity in water samples within 5 minute intervals.

The NitriTox is used in municipal and industrial waste water treatment plants in order to monitor the toxicity of incoming waste water. Even high amounts of particulate matter such as in the pulp and paper industry do not affect its operation.

The toximeter is also applicable for laboratory use as it is ready at all times and reliably measures the toxic effects of waste water on the biomass. The determination is in accordance to DIN EN ISO 9509:2006.
