Anaerobic treatment of industrial effluents (traduction du titre et sous-titre en anglais)

Dem ande chimique en oxygène (DCO); chemical oxygen demand (COD)

Quantity of O₂ required to oxidize organic and mineral substances (in the presence of a strong oxidant) present in the effluent. It is expressed in mg_O2· L^–1.

Biochemical oxygen demand (BOD); Demande biochimique en oxygène (DBO)

Quantity of O₂ required to biologically oxidize biodegradable organic matter. It is expressed in mg_O2· L^–1 and is measured at 20°C and in the dark. In France, BOD₅ is referred to as the standard 5-day analysis. To be complete, the analysis requires around three weeks at 20°C. This yields the ultimate BOD or DBO₂₁.

Nitric nitrogen (N-NO₃); nitrate

Nitrogen due to nitrates (N-NO₃ = NO₃ × 0.22).
