  Biological fermentation broth (such as nucleotides, antibiotics, organic acids, etc.) is usually separated by plate and frame filtration or centrifugation, which not only has high labor intensity, low separation accuracy, low product yield, but also has a large amount of water washing and COD emission in subsequent operation, which causes environmental problems. Because of its unique chemical corrosion resistance, high temperature resistance and high separation accuracy, ceramic membrane has become the preferred separation technology in biological fermentation industry.

Application fields:
Antibiotics: cephalosporin, colistin sulfate, streptomycin sulfate, erythromycin, vancomycin, aureomycin, rifamycin, amphotericin, lincomycin, natamycin, spectinomycin, etc
Enzyme preparations: amidase, phytase, rennet, mannanase, papain, dehydrogenase, etc
Nucleosides: inosine, guanosine, cytidine acid, citicoline, etc
Pharmaceutical intermediates: statins, pril, D-p-hydroxyphenylglycine, aminobutyric acid, mandelic acid, etc
Bulk chemical products: propylene glycol, glycerol, acrylamide, etc
Other food additives: soy sauce, cooking wine, vinegar, lactic acid Streptomyces, bear (geese) deoxycholic acid, flavors and fragrances, etc.
Technical features and advantages:
1. The separation precision is high. The ceramic membrane can be selected from 5 nm to 2 μ m, which can realize high concentration.
2. The yield of the product can be greatly improved and the mycelium can be recovered.
3. The pore size of the membrane is not easy to pollute, which can maintain high-throughput filtration and has a long service life.
4. The amount of washing water is small, the discharge of wastewater is reduced, and the COD in wastewater is significantly reduced.
5. No filter aid and coagulant are needed. The product can be operated in airtight condition at normal temperature to keep the activity of the product.
6. Fully automatic operation, greatly reducing labor intensity and saving labor cost.
