عنوان انگلیسی Removal of Ammonium from Synthetic Wastewater using Integrated Fixed Film Activated Sludge (IFAS) includes Powder Activated Carbon
چکیده انگلیسی مقاله Background & Aims of the Study: High concentration of nitrogen compounds in water and wastewater can be caused various problems and diseases such as methhemoglobinemia and eutrophication. The aim of this study was investigated nitrification and denitrification from wastewater using integrated fixed film activated sludge (IFAS) includes powder activated carbon. Materias and Methods: The laboratory scale experiments were conducted in a continuous mode. Two bioreactors containing IFAS and IFAS include powder activated carbon were utilized for evaluating of ammonium removal. Ammonia, nitrate, mass liquor suspended solid (MLSS), Suspended solid (SS) and pH were analyzed. 2.5 g/L MLSS were inoculated in 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 media can 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 the integrated fixed film activated sludge can be promoted the efficiency of ammonium efficiency.
