Abstract

Organic nitrogen concentration and nitrifying efficiency were related with aerobic reactor operation time, varying from zero up to 50 days and working as a Conventional Activated Sludge System, inoculated with sludge from a trickling filter system, packed with plastic media. The total nitrogen concentration at the beginning was adjusted to 70 mg/dm3 , by means of lysine addition and, and the corresponding to dissolved oxygen stayed at least in 3 mg/dm3 . The maximum nitrification efficiency for converting total nitrogen to nitrate was 86%, and about 30 days, was not significantly increased and the alkalinity (expressed as CaCO3) was reduced from 425 down to 57 mg/dm3 , decreasing about 7,50 mg/dm3 for each mg/dm3 of organic nitrogen converted to nitrate.
