DEMON - Processus de désammonification
Le procédé DEMON® fournit le raccourci maximum possible de la nitrification / dénitrification traditionnelle.
DEMON® involves two process steps- the partial nitritation of ammonia and the subsequent anaerobic oxidation of the residual ammonia by nitrite to nitrogen gas.
Partial nitritation requires an oxygen demand of only 40 % compared to conventional nitrification. No carbon dosage (Methanol) is required due to the autotrophic nature of the process.
The enormous impact on the consumption of resources shows the nitrogen cycle. The denitrification and nitratation not take place, the nitritation only half right. The total nitrogen removal is accomplished using only a very small amount of oxygen.
