Partial nitrification of high ammonia concentration wastewater as a part of a shortcut biological nitrogen removal process
Abstract Biological nitrification–denitrification is the most common process for nitrogen removal from wastewaters. During the first step, ammonia is aerobically oxidized to nitrite and then toExpand

Kinetic models for nitrification inhibition by ammonium and nitrite in a suspended and an immobilised biomass systems
Ammonium oxidation to nitrite nitratation and nitrite oxidation to nitrate (nitratation) were studied in a suspended biomass system (SBS) and an immobilised biomass system (IBS). Nitritation andExpand
