Raw water in the hollow fiber outside or inside the cavity pressure flow, respectively composed of external pressure type and internal pressure type. Ultrafiltration is a dynamic filtration process, the trapped material can be removed with concentrated water, do not block the membrane surface, can run continuously for a long time. Ultrafiltration membrane is one of the earliest polymer separation membranes.
Ultrafiltration technology is a kind of high and new technology widely used in water purification, solution separation and concentration, as well as the extraction of useful substances from wastewater, wastewater purification and reuse.It is characterized by simple use process, no heating, energy saving, low pressure operation and small device area .
Characteristics of hollow fiber ultrafiltration membrane
1. The filtration process is carried out at room temperature with mild conditions and no component damage, so it is especially suitable for the separation, grading, concentration and enrichment of heat-sensitive substances, such as drugs, enzymes and juice.
2. The filtration process has no phase change, no heating, low energy consumption, no need to add chemical agents, no pollution, and is an energy-saving and environment-friendly separation technology.
3. Ultrafiltration technology has high separation efficiency, and is very effective for recovery of trace components in dilute solution and concentration of low-concentration solution.
