Working Principle of Microfiltration Membranes
Microfiltration membranes are filtration membranes with pore sizes ranging from 0.1 to 1 micron, primarily used for separating suspended particles, bacteria, and large molecular colloids from liquids. The separation process relies on sieving, allowing large molecules and soluble solids (such as inorganic salts) to pass through while retaining larger suspended substances and microorganisms. The operating pressure for microfiltration membranes typically ranges from 0.3 to 7 bar, making them suitable for various liquid treatment scenarios.
