Abstract

In this study, the combination of chemical, biological and membrane processes was investigated for Landfill leachate treatment. In order to reduce the contamination level, the chemical Coagulation process was used by coagulants such as aluminum sulfate and poly aluminum chloride. Also, the optimum pH range and concentration of the coagulant were determine following by the biological process of Activated sludge. Finally, the leachate separation of the aerobic bioreactor was carried out by FO-MBR membrane process and the effect of powder activated carbon adsorbent was studied on this process. The results showed that the amount of COD in leachate decreased by 48% after pretreatment using coagulants (optimum concentration of 1 g/l and pH = 8). Then, the COD removal rate reached to 24% by using the aerobic Activated sludge process under optimum aeration conditions, F/M = 0. 312 COD/MLSS. d ratio and 24h hydraulic retention time. In the last section, the usage of synthesized cellulose membrane in form of the frame and plate modules immersed in the aerobic bioreactor of the FO-MBR process, was examined. Furthermore, 2 g/l powder activated carbon adsorbent was used to improve the performance of this process and the reduction of membrane fouling, which improved the performance of the Landfill leachate wastewater treatment system by increasing the COD removal rate from 74% to 92% as well as the changes in MLSS concentration during the 4-day FO-MBR process increased by 24% compared to the absence of adsorbent.
