BioMonitor

BOD Analyzer for Controlling WWTPs

LAR’s BioMonitor™ is an online BOD analyzer for the determination of biochemical oxygen demand (BOD), respiration and toxicity in wastewater. Using BioMonitor, operators can control their wastewater treatment plant in an optimal way.

Datasheet

The total BOD. What matters.

In contrast to the standard BOD₅ method the BioMonitor measures the total BOD. In the BOD₅measurement nitrification inhibitors are added to the sample, which suppress the degradation of nitrogen compounds. This results in the determination of the degradation of carbon compounds (carbonaceous-BOD) only and the nitrification part is not considered in BOD₅ measurements.

As a wastewater treatment plant can be reliably controlled and monitored only by the determination of total BOD, the BOD₅is insufficient for this purpose.

Alternatively to the BOD₅ measurement LAR AG provides an online respirometer, which operates like a miniature wastewater treatment plant: The BioMonitor.

The BOD analyzer degrates nitrogen and carbon compounds in special wastewater cascades, so that the meaningful total BOD can be determined within 4 minutes.
