Background and Objectives: Horizontal roughing filters (HRF) can properly remove suspended solids and microorganisms from surface water resources, especially on filtration rates less than 1.5 m/h. This research was aimed at suspended solid removal efficiency of HRF during secondary wastewater effluent filtration. Methods: This experimental study was conducted by installing an HRF pilot system on effluent pumping station of Qom wastewater treatment plant based on aerated lagoon process. The pilot was a horizontal cylindrical column consisting of three compartments filled with river gravels in various sizes. Grab samples were simultaneously taken from HRF inlet and outlet in three filtration rates: 0.5, 1, and 1.5m/hResults: The results indic...
