Background & Aim: Re-use of wastewater is an appropriate approach for development of water resources and water supply strategies. The purpose of this study was to determine the efficacy of HRF in COD removal from secondary effluent of municipal wastewater in Yasouj. Methods: The pilot which was used in the present study was a horizontal roughing filter designed and prepared according to the Wegelin’s Design Criteria. The Samples were removed daily and instantaneous based on the predicted number of samples (28 samples at each filtration rate) from the input and output filter, and then tested in the laboratory by the D5000 device. The collected data was analyzed using ANOVA and paired t-test. Results: The results indicated that the average COD removal in the filtration rate of 0.5, 1, and 1.5 were 60, 51, and 38 percent respectively. Conclusion: The average output of the HRF for all three filtration rates was lower than the maximum EPA standard of Iran.
