Numerical Simulation and Optimization Research of New Sedimentation Device

Fluent is used to simulate the different factors such as the sludge volume fraction and inlet velocity and different working conditions take effect on the sediment, to study the effect, the numerical simulation of optimized spiral inclined plate clarifiers is operated. Sedimentation efficiency of the spiral plate can be obtained form the sludge volume fraction of outlet and the removal of suspended solid, and the simulation results show that it has a very good removal rate. In order to test the spiral inclined plate sedimentation device and verify the simulation results, the experimental study is conducted. The experimental results have a good agreement with the simulation results, and it has a high removal rate.
