Hollow fiber membrane
Hollow fiber membrane
The hollow fiber membrane looks like a fiber and has a self-supporting effect. It is a kind of asymmetric membrane, and its dense layer can be located on the outer surface of the fiber/such as reverse osmosis membrane, or on the inner surface of the fiber (such as microfiltration membrane, nanofiltration membrane and ultrafiltration membrane). The wall of the membrane tube is full of micropores, and the pore diameter is expressed by the molecular weight of the material that can be retained. The molecular weight can be cut off from thousands to hundreds of thousands. The raw water flows under pressure on the outside or inner cavity of the hollow fiber membrane to form external pressure and internal pressure respectively. formula. There are two main types of hollow fiber membranes produced by Bona Bio, namely US20K and US1200HI-100. We will select suitable hollow fiber membranes for customers according to customer process requirements, different processing systems and related technical requirements.
Hollow fiber membrane characteristics：
1. Good pressure resistance
2. The hollow fiber membrane does not require a support
3. The membrane module can be made into any size and shape
4. The packing density of the hollow fiber membrane in the module is large, the membrane area per unit area is large, and the flux is large

Hollow fiber membrane technology and application
The industrial application of hollow fiber ultrafiltration membrane modules and devices can be divided into three aspects: concentration, separation of small molecular solutes, and classification of macromolecular solvents. It is widely used in water purification treatment to remove bacteria, viruses, suspended solids, microorganisms, macromolecular organic matter, colloids, heat sources, etc. in the water. It is also widely used in chemical separation, medicine and health care, food processing, filtration and purification of tea beverages, vinegar, and alcohol.
