Clarifier

 

an installation for water purification in a water-supply system. It is used to remove suspended matter and colloidal impurities from water by passing the water upward through a layer of flocculant sediment, which was previously produced by a coagulant. The rate of upward flow in the clarification zone is controlled and ranges from 0.6 mm/sec (relatively clear, low-turbidity water) to 1.4 mm/sec (high-turbidity water), depending on the impurities present. The sediment layer in the clarifier must be at least 2 m thick, and the protective layer of clarified water above it must be at least 1.5 m deep. The excess of sediment is removed through receiving ports or pipes and passes into a sediment compactor, whose volume is 20–40 percent of the clarifier volume.
