摘要: The equation governing the concentration field for a dilute suspension of particles is presented flow in circular and rectangular primary settling basins. formulation valid two‐dimensional, mean steady, isothermal, turbulent conditions. Basin velocities are obtained from hydrodynamic model which determines diffusion coefficients mass transport as part overall solution. A numerical solution to mathematical formulated by application Galerkin finite element method residuals. resulting linear, algebraic set solved standard elimination scheme. Results include contour plots particle fields basins removal efficiencies these tanks. effect partial resuspension at bed (deposition retarded) included analysis.
