Abstract—An expanded granular sludge bed packed with porous anisms, representing a tremendous challenge for
sponge was started to treat wastewater contaminated by sulfide, treatment. Heterotrophic denitrification process is often used to
nitrate, nitrite anic pounds. In inflow remove nitrite and nitrate from wastewater, whose
wastewater, potassium nitrate and sodium nitrite acted as stoichiometric reaction between glucose and nitrate is shown in
electron acceptors, sodium sulfide acted as electron donor and (1) [6]. Heterotrophic denitrification uses so anic
glucose acted anic carbon source. In the anoxic reactor, compounds as carbon and energy sources, that anic
autotrophic denitrification happe
