Filter media selection is a key process engineering step in liquid-solid separation applications, such as acid slurry filtration. By evaluating target particle retention sizing alongside clean media permeability using Darcy's Law, engineers can specify suitable pore sizes and filter materials. This calculation ensures operational efficiency, prevents premature media blinding, and maintains acceptable pressure drop limits.
