Denitrification in an anoxic rotating biological contactor under two carbon/nitrogen ratios

چکیده
CEB Biofilm Group In biological denitrification of wastewater nitrate (NO3 -) or nitrite (NO2 -) are converted into nitrogen gas (N2), in the absence of dissolved oxygen (DO) or under limited DO concentrations. A rotating biological contactor (RBC) is an attached growth bioreactor, that constitutes a very unique and superior alternative technology for carbon oxidation, phosphorus removal, nitrification and denitrification. Although in the last decade RBCs tightly closed to avoid air entrance have started to be used for denitrification, few studies have still been conducted with anoxic RBCs.

Effect of Dissolved Oxygen and Chemical Oxygen Demand to Nitrogen Ratios on the Partial Nitrification/Denitrification Process in Moving bed Biofilm Reactors
Partial nitrification was reported to be technically feasible and economically favorable, especially for wastewaterwith high ammonium concentration or low C/N ratio. In this study, the effect of dissolved oxygen (DO)and influent ratio of chemical oxygen demand to nitrogen (COD/N) ratio on biological nitrogen removal fromsynthetic wastewater was investigated. Experiments were c...

In this study, kinetics of biological carbon, nitrogen, and phosphorous removal from a synthetic wastewater in an integrated rotating biological contactoractivated sludge system was investigated. The experimental data obtained from varying four significant independent factors viz., hydraulic retention time, chemical oxygen demand for nitrogen to phosphorus ratio, internal recirculation from aer...
متن کاملDenitrification in a closed rotating biological contactor: effect of disk submergence
Several studies have employed rotating biological contactors (RBCs) for nitrogen removal. However, partially submersed disks are used for nitrification, while completely submersed disks are used for denitrification. The objective of this study was to investigate the effect of disk submergence in the performance of rotating biological contactors, in terms of the denitrification process. Two RBCs...
