Abstract

When the high-efficiency clarifier was used in the water plant to treat drinking water, the sediment flow from the flocculation zone to the sedimentation zone was quite different. Based on CFD, the high-efficiency clarifier was modelled as a whole to analyse the reasons for the sedimentation to one side. The results showed that the distribution of water volume and flow velocity was not uniform. The sediment was biased to one side and the blades rotated so that the fluid had an uneliminated circumferential velocity loop at the outlet of the lifting cylinder. The sediment concentration and flow velocity distribution in the transition section of the flocculation tank and the sedimentation tank were biased to one side, resulting in an uneven distribution of sediment concentration in this section.
