This paper presents the design of continuous sorting and concentration unit that can be used for particles or cells in the large volume of sea, waste, or fresh water. With the optimized profile of ellipse in combination with array of shield-like micropillars, efficiency of continuous sorting and concentration unit was examined by theoretical methods including Finite Element Method (FEM). With software (COMSOL 5.2) for computational fluid dynamics (CFD), we simulated unit in a laminar flow regime. Numerical results illustrate that the high velocity region which can be obtained along two side of unit and the penetration channels.
