Background & Objectives: Recently, deficient in atmospheric drop and discharges of wastewater effluents leads to serious threat for water resource. For that reason, for prevention of water source pollution and also reuse of wastewater effluents, treatment of such effluents seems to be necessary. Methods: In this work, fluidized bed reactor with a filter was used for treatment of effluents from Shahrak Gharb wastewater treatment plant. Various parameters such as BOD5, COD, TS, TP, TN and turbidity were analyzed. The aluminum sulfate was used as coagulant for enhance removal efficiency. Results: The results of present work demonstrate that present system had higher treatment potential for secondary effluents. The amount of BOD5, COD and TP in system effluents was reached to below 1.75, 3.23, 0.5 mg/L, respectively. No removal efficiency was observed for TN. In addition, the amount of turbidity in system effluent was reached to below 1.04 NTU. The system represents lower removal efficiency for TS. In addition, higher removal efficiency is in the range of 5 to 7.5 m/h and increasing of surface loading upon to 10 m/h will decreases the removal efficiency. Conclusion: On general, the system represents higher removal potential for treatment of secondary effluent for reuse application.
