The Ra-COMBO is a renowned respirometric at-line analyzer for conducting semi-automated analysis on the biolgical activity of activated sludge. The system basically measures the respiration rate (expressed as mg O2/l.h), one of the most important parameters for the biological activity of activated sludge. The analyzer determines short-term Biological Oxygen Demand (BODst) and toxicity (organic / inorganic inhibition) on grab samples of waste water or influent streams.
The unique design of the Ra-COMBO At-line Analyzer overcomes the disadvantages of other analyzer designs using two oxygen sensors. Instead, the respiration rate measurement used is a patented technology using a single DO-electrode. Today, the respiration technology used knows many references, either in a laboratory environment or in processes.
