LAR presents the NitritoxMonitor®, on-line Toxicity Analyzer using nitrifying bacteria to monitor and protects industrial and municipal wastewater treatment plants from accidental poisoning of the nitrification process by toxic substances.
Nitrifying bacteria are more sensitive than the microorganisms used in conventional bio-test methods. Continuous batch samples can be checked automatically in only five minutes to verify whether it contains toxic substances that threaten the nitrifying bacteria of the plant.
The NitritoxMonitor® measures the respiration inhibition of the nitrifying bacteria in order to determine the level of toxicity. A low oxygen turnover (respiration inhibition) indicates inhibitory substances, which have a detrimental impact on the nitrification process of the wastewater treatment plant.
Unlike other instruments, the NitritoxMonitor® is continuously ready to measure. By design the analyzer prevents possible contamination of the test organisms. By assuring the safety of the bacteria, the system is always ready for service..
Completely automated operation, robust engineering and proven filterless sample preparation with LAR's FlowSampler® ensure reduced maintenance and reliable on-line operation for many years.
