ABSTRACT:
In a high speed upward flow filtration apparatus, an upper perforated panel for receiving a fibrous lump is secured to a circumferential side plate for receiving the fibrous lump. A lower movable perforated panel for receiving the fibrous lump is vertically moved by a vertical motion cylinder, and fitted into the circumferential side plate for receiving the fibrous lump under the upper perforated panel for receiving the fibrous lump. A filter layer is formed by filling the fibrous lump between the upper perforated panel for receiving the fibrous lump and the lower movable perforated panel for receiving the fibrous lump. An unfiltered water supply diffuser is provided under the lower movable perforated panel for receiving the fibrous lump. The lower movable perforated panel is raised by the vertical moving cylinder to form a dense and uniform filter layer and to implement a high performance filtration.
