Resumen: SUMMARY The conventional Biological Nitrogen Removal (BNR) process consists on the oxidation of ammonia to nitrate (nitrification) and the subsequent reduction of nitrate to nitrogen gas (denitrification) using biodegradable COD as electron donor. If this BNR process is carried out over nitrite, it is obtained a saving of 25% of the aeration costs, the 40% of the external COD to denitrify and the 30% of sludge produced. Another feasible treatment is the combination of partial nitrification (oxidation of the 50% of NH4+-N to NO2--N) with Anammox (denitrification of NO2--N to N2 using NH4+-N ...
