Removal of Ammonium from Synthetic Wastewater Using Integrated Fixed Film Activated Sludge (IFAS) Include PowderActivated Carbon

Background & Aims of the Study: High concentration of nitrogen compounds in water andwastewater can be caused various problems and diseases such as methhemoglobinemia andeutrophication. The aim of this study was investigated nitrification and denitrification fromwastewater using integrated fixed film activated sludge (IFAS) includes powder activatedcarbon.Materials and Methods: The laboratory scale experiments were conducted in a continuousmode. Two bioreactors containing IFAS and IFAS include powder activated carbon wereutilized for evaluating of ammonium removal. Ammonia, nitrate, mixed liquor suspendedsolid (MLSS), Suspended solid (SS) and pH were analyzed. 2.5 g/L MLSS were inoculatedin the startup time. The IFAS system was operated in HRTs 8, 12 and 16 h.Results: The obtained results shows that utilization of powder activated carbon in the mediacan be cause rapid sludge production and high efficient ammonium removal process.Nevertheless, it has not effect on the carbon removal in the process.Conclusion: According to the obtained results, utilization of powder activated carbon in theintegrated fixed film activated sludge can be promoted the efficiency of ammoniumremoval.
