Biochemical oxygen demand (BOD) determination is still one of the most important parameters in water resource management. It can be used to evaluate the impact of biodegradable substances in waters and waster water. With its OxiTop ® systems, WTW offers a unique, modular and mercury-free instrument system. It is not only suitable for BOD determination, but also for measuring biodegradability and deple-tion.The advantages of Ox…

Complete packages for 6 or 12 simultaneous measurementsMeasurement using OxiTop ® is based on pressure measurement in a closed system: microorganisms in the sample consume the oxy-gen and form CO 2 . This is absorbed by NaOH, creating a vacuum which can be read directly as a measured value in mg/l BOD.The used sample volume regulates the amount of oxygen available for a complete BOD. Measurement ranges of up to 4,000 mg/l can…
