Accurate, automatic and direct control of your wastewater samples.
BOD – biochemical oxygen demand – is an expression for the quantity of oxygen required for biological degradation of organic matter in waste water sample. BOD measurement is therefore used as a basis for the detection of biologically degradable organic matter in water. The difference between BOD and chemical oxygen demand (COD) is that COD additionally registers biologically non-degradable organic matter.
BOD measurement is therefore an important measurement of the effects of domestic and industrial waste water on sewage plants and outflow points.
The Lovibond® sensor system BD 600 is a 6 sample 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 BD 600 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
|0 - 80
|0 - 200
|0 - 400
|0 - 800
|0 - 2000
|0 - 4000
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.
