Ultrafiltration membranes only allow solvents (such as water molecules), inorganic salts, and small-molecule organic substances in the solution to permeate, while retaining macromolecular substances such as suspended solids, colloids, proteins, and microorganisms in the solution, so as to achieve the purpose of purification or separation.
Ultrafiltration is a membrane separation process based on the principle of sieving separation and pressure as the driving force. The filtration accuracy is within the range of 0.005-0.01μm, which can effectively remove particles, colloids, bacteria, heat sources and macromolecular organic substances in 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 especially 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 membrane elements adopt domestic or imported membrane company products to ensure that customers get organic membrane elements, thereby ensuring retention performance and membrane flux.
The system has a high recovery rate and high-quality products, which can realize material separation, purification and high-fold concentration.
There is no phase change in the treatment process, no adverse effect on the composition of the material, and the separation, purification, and concentration process is always at room temperature. It is especially suitable for the treatment of heat-sensitive substances, which completely avoids the destruction of biologically active substances by high temperature. Disadvantages, effectively retain the biologically active substances and nutrients in the raw material system.
The system has low energy consumption and short production cycle. Compared with traditional process equipment, the equipment operation cost is low, which can effectively reduce production costs and improve the economic benefits of enterprises.
The system has advanced technological design, high degree of integration, compact structure, small footprint, simple operation and maintenance, and low labor intensity.
The system is made of sanitary pipe valves with clean and hygienic on-site materials that meet the requirements of GMP or FDA production specifications.
The control system can be individually designed according to the user's specific requirements, combined with advanced control software, on-site centralized monitoring of important process operating parameters, to avoid manual misoperation, and multi-directional to ensure the long-term stable operation of the system.
Mainly include food industry, beverage industry, dairy industry, biological fermentation, biomedicine, pharmaceutical chemicals, biological preparations, traditional Chinese medicine preparations, clinical medicine, printing and dyeing wastewater, food industry wastewater treatment, resource recovery and environmental engineering, etc.
Mineral water: In mineral water manufacturing, ultrafiltration technology is applied. In engineering design, the pore size and type of membrane will be selected according to the source water quality analysis report of mineral water, and the ultrafiltration design will be designed.
Food: Ultrafiltration technology is gradually adopted in the production of dairy products, fruit juices, wines, condiments and other foods, such as the separation of protein and low molecular weight lactose in milk or whey from water, clarification and sterilization of fruit juices, and color in wine The removal of protein, polysaccharides and other colloidal impurities, and the removal of bacteria in soy sauce and vinegar, show the advantages of economy, reliability, and quality assurance compared with traditional methods.
Medicine: In the production of medicine and biochemical industry, it is often necessary to separate and purify heat-sensitive substances. Ultrafiltration technology shows its outstanding advantages for this. The use of ultrafiltration to separate and concentrate biologically active substances (such as enzymes, viruses, nucleic acids, special proteins, etc.) is quite suitable for drugs extracted from animals and plants (such as alkaloids, hormones, etc.). The extracts often contain large molecules or In many cases, solid matter can be separated by ultrafiltration to improve product quality.
Pure water, ultrapure water: primary purification of industrial water, RO pretreatment of pure water and ultrapure water preparation, and terminal treatment of pure water and ultrapure water.
Environmental protection: advanced treatment of industrial wastewater, urban reclaimed water reuse system, electrophoresis paint and oil recovery.
Fermentation: separation and refining of biochemical fermentation broth, concentration and refining of enzymes, clarification and filtration of sugar and xylitol.
