Grout bridge for filter underdrain blocks
A filtration system 11 comprising a plurality of underdrain blocks 12a, 12b arranged side by side and configured to define a gap there between to receive grout with each block comprising a top wall 14, bottom wall 16 and a plurality of side walls 18, and a grout bridge 10 is arranged in the gap between adjacent underdrain blocks so as to form a grout seal between the grout bridge and adjacent side walls of the adjacent walls of the adjacent underdrain blocks wherein the adjacent sidewalls each comprise a rib 24 where each rib defines a slot 26 and the grout bridge is arranged in adjacent slots of the adjacent sidewalls of the adjacent underdrain blocks. The filtration system may further comprise a filter floor over a flume, wherein the plurality of underdrain blocks sit on the filter floor and the grout bridge may be arranged substantially horizontally. A method of arranging a filtration system is also claimed. Further claimed is a grout bridge for a filtration system. The filtration system is found in gravity or pressure filters where the liquid is filtered and passed through to an underdrain block.
