Ultrafiltration equipment
Ultrafiltration membrane microfiltration and nanofiltration lies between a membrane filter, applicable to material separation, concentration and purification of a membrane separation technology. It in practical applications \ the general characterization of a molecular weight cut-off, mainly for the solution of macromolecules, and colloidal particles and solvent, such as the separation of small molecules. So that large molecules, such as colloidal and particulate retention in the membrane surface, away from the material circulation and has become a concentrated liquid, to material separation, concentration and purification purposes. Ultrafiltration applications mainly related to food, beverage, bio-pharmaceuticals, fine chemicals, industrial wastewater treatment and reuse and so on.
Ultrafiltration membrane technology
In China, the application of ultrafiltration technology in fruit juice clarification process has a dominant position. Squeeze the juice out of the new contain pectin, pulp debris, starch, protein, suspended solids, microbial metabolism and other substances resulting in turbid juice.
The use of ultrafiltration for clarification of fruit juices, which will enable the sugars, organic acids and water molecules through the membrane, and retained most of macromolecular substances, the juice is clarified sterile; ultrafiltration filter aid is no need; short process , labor costs are low; is more cost-effective method to clarify the juice.
Industrial production concentrated enzyme preparation of the separation can be operated at room temperature to overcome the heat of fermentation product quality of preparation; to remove the small molecule impurities, the filtrate to ensure purity and quality of the good; filtration processes without phase change, energy consumption and costs are lower than traditional methods; equipment is simple, easy to operate and control, which soon became a bio-pharmaceutical industry of choice for separation of enrichment technology.
Application areas:
Dairy products, fruit juice, vegetable juice, such as clarification, concentration
Animals and plants (aloe vera, Luohanguo, tea, etc.) extract active ingredients
Soy protein, oligosaccharides, isoflavones, such as extraction, concentration
Antibiotics, amino acids, VC and other fermented liquid purification, enrichment
Traditional Chinese Medicine (Chaihu, Salvia, Scutellaria, etc.) purification of the active ingredient injection, separation
Sterilization of medical pure water, in addition to the original heat, separation of drug concentration;
Polysaccharides (Ganoderma lucidum, Grifola frondosa, mushrooms, etc.) material purification, enrichment
Fluorescent Brighteners desalination, concentration
Electrophoresis paint recovery and reuse of water
PVA desizing textile waste water reuse, recycling fiber processing agents, scouring wastewater recycling lanolin.
Ultra-pure water the semiconductor industry, integrated circuit terminals clean water treatment;
Water treatment works: Preparation of mineral water, drinking water purification, reverse osmosis and ultrafiltration as a pretreatment;
Wastewater treatment works: industrial wastewater treatment, municipal wastewater treatment and reuse. |
