Biochemical Oxygen Demand (BOD) is an expression for the quantity of oxygen required for biological degradation of organic matter in a waste water sample. BOD measurement is used as a basis for the detection of biologically degradable organic matter in water and is therefore an important measurement of the effects of domestic and industrial waste water on sewage plants and outflow points. The difference between BOD and Chemical Oxygen Demand (COD) is that COD additionally registers biologically non-degradable organic matter.
The Lovibond BD606 is a 12 sample sensor system that allows precise measurements of BOD based on the manometric principle. Manometric respirometers relate oxygen uptake to the change in pressure caused by oxygen consumption while maintaining a constant volume. Thanks to the modern integral pressure sensors, it is no longer necessary to use mercury for pressure measurements.
The BOD level of a sample depends on the quantity of organic matter present, which can vary considerably. The Lovibond BOD measuring system BD606 is therefore calibrated for the various sample volumes and the corresponding measuring ranges listed below. The overall measuring range of the system is 0 - 4000 mg/L
Range (mg/L BOD)
Sample Volume(ml)
0 - 40
428
0 - 80
360
0 - 200
244
0 - 400
157
0 - 800

0 - 2000
56
0 - 4000
21.7
For all measuring ranges the BOD is shown directly in mg/L
Applications include waste water, determination of biological activity, water treatment plants, analytical laboratories and scientific research.
