| description | An apparatus, such as a granular media filter, for treating liquid, such as wastewater, including a settler assembly for reducing media loss during high-turbulence washing of media in the granular media filter. The settler assembly is comprised of plates, tubes, or other porous materials placed between a system of baffles and a backwash trough. The settler assembly reduces turbulence near the overflow weir edge of the backwash trough, thereby reducing media carry over with the backwash water into the backwash trough. The trough baffle settler assembly will allow higher backwash rates per backwash with the same or lower media losses than experienced with previous trough-baffle designs, thereby reducing costs of construction and operation of granular media filter systems. The settler assembly is particularly adapted for use with granular media filters employing simultaneous application of air and water to produce a high turbulence backwash. |
