| Abstract | Anammox process was established at laboratory level using seed sludge from activated sludge process. Initial biomass concentration of 1.5 g VSS L-1 was maintained in the reactor. Gas-lift reactor of 4.9 L in working volume size was employed in the process. Process start-up was accomplished using gradual increase in nitrogen load. Nitrogen consumption rate of 1.3 kg N m3 d-1 was achieved in 28 days. Biomass showed specific nitrogen activity of 1.0 g N g vss-1 d-1 • Furthermore, process intermediates such as hydrazine and hydroxylamine which play important role in anammox process also were analyzed. Hydrazine was not detected but hydroxylamine in the effluent was found to be up to 0.15 mg N L-1 • Sulfide formation also was detected up to 43 .8 mg S L1 whenever N02--N concentration in effluent was reduced to near zero confirming use of so/-as electron acceptor whenever nitrite was not available. |
