High-efficiency sedimentation technology is a new type of clarifier following horizontal flow sedimentation tanks, inclined plate (tube) sedimentation tanks, and mechanical accelerated (pulse) clarifiers. It integrates the functions of chemical dosing reaction, coagulation, flocculation, sedimentation, and sludge thickening into one unit, and is divided into a chemical dosing reaction zone, a mixing zone, a flocculation zone, a sedimentation zone, and a pH adjustment zone. Through high-efficiency sedimentation technology, pollutants such as suspended solids, hardness, silicon, and fluorine in sewage can be removed.
