Özet

Effect of synthetic wastewater composition on COD removal performance of a continuous column bioreactor with recycle was studied. Zooglea ramigera was used as dominant microbial culture throughout the experiments. Synthetic wastewater was composed of diluted molasses, urea, KH2PO4 and MgSO4. Wastewater composition was changed by adjusting influent COD/N/P ratio between 100/7/1-100/15/1. System was operated with nitrogen and COD limitations and COD removal performances were compared. Both nitrogen and COD removal efficiencies and rates were calculated and optimum feed COD/N ratio was determined to be between 100/8-100/10.
