Water treatment throught a De-nitrification process

De-nitrification is the biological process that reduces molecular gaseous nitrogen.
It is mainly realized in an anoxic tank, put in front of the actived sludge one, powered by the effluent from the primary treatments, from secondary sedimentation sludge return and turbid return from the oxidation tank.

The quantity of nitrogen in the effluent treated is reduced and is subsequently released, Through de-nitrification.
The de-nitrifying micro-organisms metabolise the organic substance using nitrate oxygen as the oxygen source and reducing it to nitrogen.

Therefore, the residual products of the de-nitrification reaction, are micro-organisms and gaseous nitrogen.
The reaction occurs in specific tanks in which sludge return containing de-nitrifying bacteria and/or effluent, containing nitrates and deriving from the oxidation-nitrification process, the inward waste water containing biodegradable organic carbon come into contact.
