COD Analysis

What COD means and how it is measured.

The COD value indicates the amount of oxygen which is needed for the oxidation of all organic substances in water and is thus an important indicator for water analysis. It is considered in the planning and controlling of treatment, as well as assessing its efficiency, thus forming the basis for the calculation of waste water charges.

The COD can be determined in a laboratory or online, whereby these methods significantly differ in duration and consumables used.
