Product Description
Hollow fiber ultrafiltration membrane (4 inches, 6 inches, 8 inches) UF Ultrafiltration
UF Ultrafiltration
An overview
Membrane separation and the nature of the evolution and prevalence of the metabolism of organisms, after half a century of development, industrial production began to play a pivotal role. The membrane separation technology, as one of this century, the six high-tech, low-voltage operation at room temperature under its no phase change, low energy consumption and other significant advantages, its application has been involved in water purification, beverages and foodstuffs, medicine, water, health and the environment processing and other aspects.
UF Ultrafiltration
Second, classification
UF different ways according to the structure can be divided into roll, flat, tubular, hollow fiber type, bellows; by application of different membrane materials can be divided into polypropylene, acrylonitrile, modified PVC ethylene, polysulfone, PVDF membrane, etc.;
The hollow fiber membrane to the different ways water can be divided into internal pressure type hollow fiber membrane and the external pressure type hollow fiber membrane; the Austrian part of the original hollow fiber membrane pressure hollow fiber membrane

Product Name: membrane, hollow fiber membrane,
Ultrafiltration Technology:
First, the ultrafiltration principle: Ultrafiltration is a membrane separation technology, relying on fluid shear and pressure driven flow filtration process to separate particles according to molecular size, the pressure difference as the driving force, raw material liquid flows in the membrane surface , raw material liquid solvent and small solute particles from high-pressure liquid side of the low pressure side through the membrane, dissolved substances and smaller than the membrane pore through the membrane material will be used as through the liquid commonly referred to as the filtrate or through the fluid, not through the membrane material will be retained by the ultrafiltration membrane, was commonly known as interception of part of the concentrated liquid, concentrated liquid remaining in the filter medium concentration, to reach the solution purification, separation and enrichment purposes .

Second, the material mainly isolated ultrafiltration: gel (non-reactive silica, iron, aluminum), bacteria, viruses and protozoa and other microorganisms, molecular weight macromolecules in 2000-50 Dalton (protein, amino acids, enzymes).
Third, the ultrafiltration characteristics:
1, the solution can be achieved ultrafiltration purification, separation and concentration of purpose, is a highly efficient, environmentally friendly, energy-saving separation process;
2, a lower pressure as the driving force to achieve separation of particles by molecular weight, such as the preparation of pure mineral water, industrial water recycling and reuse;
3, the ultrafiltration separation process are temperatures near room temperature, low power, no phase change, in food processing, pharmaceutical industry, biotechnology and other fields have their own unique application value;
4, the ultrafiltration process, the size and capacity to adapt to a wide range of equipment, compact structure, easy integration with other separation unit, and automatic control. If UF + RO membrane desalination has become recognized as the best combination of water treatment
5, membrane oxidation resistance wire, suitable for a wide range of processing liquid; wire through the hydrophilic membrane modification, outer wall smooth, anti-pollution performance, film silk water production rate per unit of time decay.

UF works: UF is a kind of screening for the separation principle, to pressure-driven membrane processes, filtration in the 0.005-0.01μm range, can effectively remove particles, colloids, bacteria, heat and polymer organic material. Can be widely used material separation, concentration and purification. No phase transformation during ultrafiltration, room temperature operation, the separation of heat-sensitive material is particularly suitable, and has good heat resistance, acid and alkali, and resistance to oxidation, can be below 60 ℃, pH 2-11 under the conditions for the long-term continuous use . Classification of membrane: membrane into plate and frame type according to the structure (plate), hollow fiber, tube, roll and other structures. Among them, the hollow fiber ultrafiltration membrane technology is the most mature and advanced form. Hollow fiber diameter of 0.4-2.0mm, inner diameter 0.3-1.4mm, the wall covered with porous hollow fiber, the aperture in order to retain the molecular weight of material expression, molecular weight cutoff up to several thousand to hundreds of thousands. Raw water in the outer or inner chamber pressure hollow fiber flow, respectively, constitute the external pressure and internal pressure type hollow membrane. Ultrafiltration is a dynamic filtering process, are retained material can not rule out the plug with the concentrated liquid film surface, long-term continuous operation. Membrane application areas: * Preparation of pure and ultrapure water as RO pretreatment and terminal handling ultra-pure water; * for the separation of bacteria in industrial water, heat, colloidal, suspended impurities and organic macromolecules; * drinking water, mineral water purification; * fermentation, enzyme preparation industry, the pharmaceutical industry concentration, purification and clarification; * fruit juice concentration, separation; * soybeans, dairy, sugar industry, wine, tea, vinegar's separation, concentration and clarification; * industrial wastewater and domestic wastewater purification and recycling; * electrophoretic paint recycling ... ...
