Underdrain structure for media filters |
摘要 |
An underdrain for a media filter used to filter liquids. The media particles rest on a pair of perforated plates having offset perforations. The plates are spaced apart a distance less than the size of the media particles. This allows the filtered liquid to flow through the plates but blocks passage of the media particles through the plates.
