Abstract: A grid bar for a screen grid of a screen includes a multiple number of grid bars arranged next to each other and spaced apart from each other, which serves the purpose of separating screening material from a flowing liquid, such as wastewater flowing in a sewer channel. The grid bar includes a plastic reinforced with fibers, whereas at least a part of the fibers extend in a longitudinal direction of the grid bar. A screen includes such a screen grid.

Abstract: The invention relates to a grid bar for a screen grid (2) of a screen (3) comprising a multiple number of grid bars (1) arranged next to each other and spaced apart from each other, which serves the purpose of separating screening material from a flowing liquid, such as wastewater (5) flowing in a sewer channel (4). In accordance with the invention, it is proposed that the grid bar (1) consists, at least partially, of a plastic reinforced with fibers (6), whereas at least a part of the fibers (6) extend in a longitudinal direction of the grid bar (1). In addition, a screen (3) with a corresponding screen grid (2) is proposed.

Abstract: The invention refers to a filter segment for use in a filtration device, especially a rotating filter for filtering liquids with a frame element (1) made at least partly of plastic and a filtration surface enclosing it, in which at least a flat filter material (2) spanning the filtration surface is embedded. According to the invention, it is suggested that within the frame element (1) at least one reinforcement (3) is arranged, for example, like a reinforcement frame and/or individual reinforcing elements traversing the entire frame element (1).
