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) . Patented respiration technology • Continuous use of real sludge from WWTP for measurement • Measurement at same pH as WWTP • Measurement at same temperature as WWTP • Direct BODst related measurement by using respiration rate instead of oxygen concentration • Field proven technology General features Human interface: 10.4" color touch screen with excellent viewing angle and graphics. Can remotely be taken over by LAN ethernet software ( VNC) . Visualization of the BOD and respiration activity in real-time Standard auto-cleaning First class and robust moving components such as low-speed peristaltic pumps and patented single O2 electrode Respiration Module. Incorporated industrial PC with result & alarm data export ( 1000 results including sample stream, date, time) Multifunctional sealed USB port on left side of the housing ( result download, program upload, reporting) Communication: active 4 - 20 mA, Ethernet, RS232, TCP-IP Weight: 65 kg ( 144 lbs.)
