6. Large Pitch Conveyor Chains
6.3.8 Sewage Treatment Chain (Bar Screen) Large conveyance: Sewage treatment equipment Application Example At the water gate of sewage treatment plants, there are gratings—called bar screens—arranged lengthwise to catch floating objects. In addition to water treatment plants, bar screens may be installed at the mouths of rivers. In some bar screen setups, chains are set on guide rails and used as wide gratings or screens. (See Figures 6.33 and 6.34.) Eventually gratings fill up with contaminants, and they have to be cleaned. A comb-shaped rake installed between two strands of chain is used for this purpose.
