Ra-BOD® On-line BOD analyzer
The Ra-BOD® is a unique process analyzer for determining short-term Biological Oxygen Demand (BODst) in waste water and surface water and fits into a control strategy for activated sludge plants. The respiration rate (expressed as mg O2/l.h) is one of the most important parameters for the biological activity of activated sludge. Consequently, the determination of the respiration rate is of great importance in gaining insight in activated sludge plants. The unique design of the Ra-BOD® On-line BOD 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.
The respiration technology as applied is also available in the at-line analyzer Ra-COMBO® for determining BODst or toxicity (see below).
