Determination of the intrinsic kinetic parameters of sulfide-oxidizing autotrophic denitrification in differential reactors containing immobilized biomass

► Intrinsic kinetic parameters of sulfide-oxidizing autotrophic denitrification. ► Sulfide as electron donor and nitrate/nitrite as electron acceptors. ► Negligible external and internal mass transfer resistance. ► Half-order kinetic model for biofilm applied to systems with attached cells. ► Intermediary sulfur compounds production from partial sulfide oxidation.
