Özet

In this study, the treatability of old landfill leachates by means of Submerged Membrane Bioreactor (SMBR) followed by a rotary hybrid reactor based on the Hydrodynamic Cavitation Ozonation process was investigated. The SBMR was operated under various flux rates (3, 6, 12 and 18 L/m2.hour) for 425 days. For the SMBR, an average 32.6% COD removal efficiency was achieved. After the ozonation of effluent water from the SMBR in a rotary-based Hydrodynamic Cavitation Reactor (HDCR) with a different number of passes, the COD (chemical oxygen demand) removal efficiency of the hybrid system increased up to 95.8%. Findings show that HDCR is likely to be an intensification process for the treatment of wastewater for which biological treatment methods are mostly inapplicable.
