Ultrafiltration membrane equipment water purification system is widely used in beverage water treatment industries Chinese manufacturer ZZ

Hollow fiber ultrafiltration membrane is a kind of ultrafiltration membrane. It is the most mature and advanced technology in ultrafiltration technology. Hollow fiber The hollow fiber tube wall is full of micropores, and the pore size is relatively large for the molecular weight of the material that can be retained, and the molecular weight can be several thousand to several hundred thousand.

The raw water flows under pressure on the outside of the hollow fiber or in the inner cavity to form an external pressure type and an internal pressure type respectively. Ultrafiltration is a dynamic filtration process. The retained substances can be removed with the concentrated water without clogging the membrane surface, and it can run continuously for a long time. Ultrafiltration membrane is one of the first polymer separation membranes developed.

Ultrafiltration technology is a high-tech technology widely used in the field of water purification, solution separation, concentration, and extraction of useful substances from wastewater, and wastewater purification and reuse. It is characterized by simple use process, no heating, energy saving, low-pressure operation, and small device footprint.

1. The filtration process is carried out at room temperature, with mild conditions and no component damage, so it is particularly suitable for the separation, classification, concentration and enrichment of heat-sensitive substances such as drugs, enzymes, fruit juices, etc.

2. There is no phase change in the filtration process, no heating, low energy consumption, no chemical reagents, no pollution, and it is an energy-saving and environmentally-friendly separation technology.

3. Ultrafiltration technology has high separation efficiency and is very effective for the recovery of trace components in dilute solutions and the concentration of low-concentration solutions.

4. The ultrafiltration process only uses pressure as the power of membrane separation, so the separation device is simple, the process is short, the operation is simple, and it is easy to control and maintain.

The filtration accuracy is within the range of 0.005-0.01μm, which can effectively remove particles, colloids, worms, heat sources and polymer organic substances in the water. It can be widely used in the separation, concentration and purification of substances. The ultrafiltration process has no phase inversion and is operated at room temperature. It is particularly suitable for the separation of heat-sensitive substances. It has good temperature resistance, acid and alkali resistance and oxidation resistance. It can be continuous for a long time under the conditions of below 60℃ and pH 2-11 use.

Ultrafiltration is a membrane separation process based on the principle of sieve separation and pressure as the driving force.

Hollow fiber ultrafiltration membranes are widely used in the preparation of mineral water due to their special properties; pretreatment of reverse osmosis equipment; purification treatment of tap water; pretreatment of seawater desalination; purification treatment of wastewater reuse; removal of colloids and bacteria in water; filtration In addition to the large molecular weight impurities, protein and polysaccharides in the Chinese medicine extract, the Chinese medicine preparation is finally prepared; the effective ingredients of the Chinese medicine are concentrated, and the water and small molecular weight impurities in the liquid are filtered out; low alcohol liquor is turbid and sterilized; fruit wine, beer and Refining of other wines; purifying tea juice to prepare concentrated tea; removing heat sources from injections and large infusions; concentrating human serum.

The special ultrafiltration equipment for pollution engineering removes impurity particles of a certain size in the water by means of physical retention. Driven by pressure, water, organic low molecules, inorganic ions and other small-sized substances in the solution can reach the other side of the membrane through the micropores on the fiber wall, and large-sized bacteria, colloids, particles, and organic macromolecules in the solution The substance cannot penetrate the fiber wall and is retained, so as to achieve the purpose of sieving different components in the solution.

The combination of ultrafiltration membrane filaments into a component that can be connected to an ultrafiltration system is called an ultrafiltration membrane module. Ultrafiltration membrane modules are divided into three types: internal pressure type, external pressure type and submerged type. The driving force of submerged ultrafiltration membrane filtration is the pressure difference between the vacuum inside the membrane tube and the atmospheric pressure.
