Filter disk segments

Abstract

A filter disk segment (500) comprising (a) a filter element disk (400) comprising a central hub (401) having a central hub opening (402); (i) a first porous component (100) including a first end (101) by the central hub opening, and a second end (102) distal to the first end, the first porous component having an upper surface (110), the upper surface including at least two raised fluid flow channels (112), each of the at least two raised fluid flow channels having an inner diameter (112B) and an arch-shaped porous wall (112A), each of the at least two raised fluid flow channels extending toward the first end and the second end, and a lower surface (120) facing a drainage component (300); (ii) a second porous component (200) including a first end (201) by the central hub opening, and a second end (202) distal to the first end, the second porous component having an upper surface (220) facing the drainage component (300) and a lower surface (210), the lower surface including at least two raised fluid flow channels (212), each of the at least two raised fluid flow channels having an inner diameter (212B) and an arch-shaped porous wall (212A), each of the at least two raised fluid flow channels extending toward the first end and the second end; wherein each of the at least two raised fluid flow channels in the first porous component and in the second porous component are curved in shape between the first end and the second end; (iii) the drainage component allowing fluid flow therethrough arranged between, and in fluid communication with, the first porous component and the second porous component, the drainage component including the central hub opening; wherein the central hub supports the first porous component, the second porous component, and the drainage component.
