UF Membrane Hollow Fiber And Industrial Ultrafiltration Membrane System
First, the working principle of ultrafiltration equipment:
Ultrafiltration is a membrane separation process with separation principle and pressure as the driving force. The filtration precision is in the
range of 0.005-0.01μm, which can effectively remove particles, colloids, bacteria, heat sources and high molecular organic substances in water.
Can be widely used in the separation, concentration and purification of substances. The ultrafiltration process has no phase transformation and
is operated at room temperature. It is especially suitable for the separation of heat sensitive substances. It has good temperature resistance,
acid and alkali resistance and oxidation resistance. It can be continuously continuous under conditions of 60 ° C and pH 2-11. use.
2. Classification of ultrafiltration membranes:
The ultrafiltration membrane is divided into a plate-and-frame type (plate type), a hollow fiber type, a nanometer membrane type ultrafiltration
membrane, a tube type, a coil type, and the like according to a structural type. Among them, hollow fiber ultrafiltration membrane is the most
mature and advanced form of ultrafiltration technology. The hollow fiber has an outer diameter of 0.4-2.0 mm and an inner diameter of 0.3-1.4
mm. The hollow fiber tube wall is covered with micropores, and the pore diameter is expressed by the molecular weight of the retentate
substance, and the molecular weight cut off can be several thousand to several hundreds of thousands. The raw water is pressurized and flows
outside or inside the hollow fiber to form an external pressure type and an internal pressure type hollow ultrafiltration membrane. Ultrafiltration is
a dynamic filtration process in which the retained material can be removed with the concentrate without clogging the membrane surface and can
be continuously operated for a long period of time.
3. Application of ultrafiltration technology:
Early industrial ultrafiltration was applied to wastewater and wastewater treatment. Over the past 30 years, with the development of ultrafiltration
technology, the application fields of ultrafiltration membrane technology have been extensive, including food industry, beverage industry, dairy
industry, biological fermentation, biomedicine, pharmaceutical and chemical, biological preparations, and traditional Chinese medicine.
Preparation, clinical medicine, printing and dyeing wastewater, food industry wastewater treatment, resource recovery, and environmental
engineering.
