✦ Synopsis

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, KH2PO 4 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.

During wastewater treatment, biofilm-coated sand particles stratified in a fluidized bed bioreactor (FBB); particles coated by thicker biofilm segregated toward the top of the bed. Stratification was so well developed that at least two co-existing regions of significantly different mean biofilm thic
