Small ultrafiltration equipment is a membrane separation technology device that can purify and separate solutions. The ultrafiltration membrane system is a solution separation device that uses ultrafiltration membrane fibers as the filtration medium and the pressure difference on both sides of the membrane as the driving force. Ultrafiltration membranes only allow solvents (such as water molecules), inorganic salts, and small organic molecules in the solution to pass through, while intercepting large molecular substances such as suspended solids, colloids, proteins, and microorganisms in the solution, thereby achieving the purpose of purification or separation.
1Small ultrafiltration equipmentWorking Principle:
Ultrafiltration is a membrane separation process that uses sieving as the separation principle and pressure as the driving force. The filtration accuracy is in the range of 0.005-0.01 μ m, and it can effectively remove particles, colloids, bacteria, heat sources, and high molecular weight organic substances from water. It can be widely used for the separation, concentration, and purification of substances. The ultrafiltration process has no phase transformation and operates at room temperature, making it particularly suitable for the separation of thermosensitive substances. It has good temperature resistance, acid and alkali resistance, and oxidation resistance, and can be used continuously for a long time below 60 ℃ and pH 2-11.
2、 Small sizeAdvantages of ultrafiltration equipment:
A. The control system can be personalized according to users' specific usage requirements, combined with excellent control software, to centrally monitor important process operating parameters online on site, avoiding manual errors and ensuring long-term stable operation of the system from multiple perspectives.
B. The system has a high recovery rate and produces high-quality products, which can achieve efficient separation, purification, and high fold concentration of materials.
C. The processing process has no phase change and has no adverse effects on the composition of the material. The separation, purification, and concentration processes are always at room temperature, making it particularly suitable for the treatment of thermosensitive substances. This avoids the disadvantage of high temperature damaging bioactive substances and effectively preserves the bioactive substances and nutrients in the raw material system.
D. The system has low energy consumption, short production cycle, and lower operating costs compared to traditional process equipment. It can effectively reduce production costs and improve the economic efficiency of enterprises.
E. The system has excellent process design, high integration degree, compact structure, small footprint, easy operation and maintenance, and low labor intensity for workers.
F. The system is made of sanitary grade control valves, and the site is clean and hygienic, meeting the requirements of GMP or FDA production standards.
3、 Application Fields
Mineral water: In the production of mineral water, ultrafiltration technology is applied. In engineering design, the pore size and membrane type of the membrane will be selected according to the water quality analysis report of the mineral water source, and ultrafiltration design will be designed accordingly.
◆ Food: Ultrafiltration technology is gradually adopted in the production of dairy products, fruit juice, wine, seasonings and other food products, such as the separation of protein and low molecular weight lactose from water in milk or whey, clarification and sterilization of fruit juice, removal of colored proteins, polysaccharides and other colloidal impurities in wine, and removal of bacteria in soy sauce and vinegar. Compared with traditional methods, it has shown advantages such as economy, reliability and quality assurance.
◆ Medicine: In the production of medicine and biochemistry, it is often necessary to separate and purify thermosensitive substances, and ultrafiltration technology has shown its outstanding advantages in this regard. The use of ultrafiltration to separate and concentrate bioactive substances (such as enzymes, viruses, nucleic acids, special proteins, etc.) is quite suitable for extracting drugs from plants and animals (such as alkaloids, hormones, etc.). The extract often contains large molecules or solid substances, which can be separated by ultrafiltration in many cases to improve product quality.
Pure water and ultrapure water: primary purification of industrial water, RO pretreatment for pure and ultrapure water preparation, and terminal treatment for pure and ultrapure water.
Environmental Protection: Advanced treatment of industrial wastewater, urban water reuse system, recycling of electrophoretic paint and oil products.
