Abstract

The disclosure relates to a disc filter panel comprising a frame (2), the panel comprises an open area for media filtration and a filter cloth (6) that covers this area. The frame (2) includes an outside portion (4) with a base surface (9) featuring a screen pattern, which defines a fuse surface. The filter cloth (6) includes a filtration area (7) and a surrounding connecting zone (8), which is thermally bonded to the fuse surface of the screen pattern, ensuring secure attachment and structural integrity. This configuration enhances the durability and performance of the filter panel by providing a robust and uniform connection between the filter cloth (6) and frame (2). A method for assembling the disc filter panel (1) is also disclosed, involving the application of heat and pressure via a heating device to thermally bond the connecting zone (8) of the filter cloth (6) to the screen pattern, forming a reliable and efficient filtration component.
