Microfiltration Membranes

‌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.







Key Features:






High Filtration Precision: Microfiltration membranes ensure accurate filtration by precisely controlling pore size and distribution, effectively removing particles in the range of 0.1 to 1 micron.

High Surface Porosity: The surface porosity of microfiltration membranes can reach up to 70%, allowing filtration speeds to be over 40 times faster than comparable filter papers with the same retention capability.

Low Adsorption Loss: Due to their thin structure, microfiltration membranes experience minimal loss from liquid adsorption during the filtration process.

No Medium Shedding: The structure of polymeric microfiltration membranes is continuous and uniform, preventing medium shedding during filtration and avoiding secondary contamination, thus ensuring high purity of the filtrate.

Compact Structure and Strong Applicability: The compact design of the membrane modules allows for adjustment of channel width to accommodate liquids of varying viscosities, making them suitable for diverse processing needs.
