Microporous Filtration Process

Microporous filtration is a sieving process and belongs to precision filtration. Microporous precision filtration refers to a filtration technology that filters out particles from 0.1 μm to 10 μm. Generally speaking, the filtration mechanism is divided into two types: surface type and deep layer type. Microporous filtration is a sieving process and belongs to precision filtration. The filtration mechanism of MF membrane manufactured by advanced technology is surface filtration. Because the filter aperture is fixed, the accuracy and reliability of the filter can be ensured. Deep-layer filtration is divided into non-fixed irregular pore size and fixed irregular pore size. The former, such as a chemical fiber wound filter element, is generally only used as a rougher pre-filter.

The application of microporous membranes is extremely wide. Nowadays, the microporous membranes used in many MF applications are usually disposable and have a short service life. The life of the microporous components for air filtration can be up to several months, while the life of the components for filtering bulk liquids can be as short as several hours.
