Özet

A rotating biodisc contactor (RBC) was used for biological treatment of synthetic saline wastewater with and without sludge (cell) recycle. Synthetic wastewater composed of diluted molasses, urea, KHzPO4, MgSO4 and 3% salt (NaCl) was fed to the RBC unit with different flow rates. Underflow from a sedimentation tank placed at the end of RBC unit was recycled to the RBC unit with a constant flow rate. COD removal rates and efficiencies were determined for the cases of with and without sludge recycle and compared.
