Membrane separation technology empowers the high-quality upgrading of the biopharmaceutical industry
With the rapid development of the biopharmaceutical industry, drug purity, production efficiency, and environmental friendliness have become core industrial demands. As a high-efficiency, energy-saving, and high-precision separation technology, membrane separation technology has been widely applied in the biopharmaceutical field due to its unique advantages, becoming a key technical support for promoting the high-quality development of the industry.
1. Core Principle of Membrane Separation Technology and Its Compatibility with the Biopharmaceutical Industry
Membrane separation technology is a physical process that uses a semi-permeable membrane as the core medium to achieve selective separation based on differences in molecular size, shape, polarity, etc., of materials under the driving force of pressure, concentration difference, etc. Its core advantages include high separation precision, no need for chemical agents, normal temperature operation without damaging active ingredients, and low energy consumption, which are highly consistent with the core needs of the biopharmaceutical industry for drug activity retention, purity control, and green production.
The biopharmaceutical industry involves the production of various products such as antibiotics, vitamins, bioenzymes, traditional Chinese medicine preparations, and blood products. Its core links include fermentation broth filtration, active ingredient purification, concentration and desalination, sterilization and impurity removal, etc. Traditional separation technologies such as plate and frame filtration, centrifugal separation, and diatomaceous earth filtration have problems such as low precision, high energy consumption, and easy introduction of impurities. Membrane separation technology can specifically solve these pain points and provide efficient and stable separation solutions for biopharmaceuticals.
2. Core Application Scenarios of Membrane Separation Technology in the Biopharmaceutical Industry
(1) Fermentation Broth Filtration and Impurity Removal
The production of antibiotics (penicillin, cephalosporin), vitamins (vitamin C, vitamin B2), enzyme preparations (protease) and other products in biopharmaceuticals all rely on fermentation processes. The fermentation broth contains a large number of impurities such as bacteria, miscellaneous proteins, colloids, and inorganic ions. The use of ultrafiltration membrane and microfiltration membrane systems can achieve precise filtration of the fermentation broth, efficiently remove bacteria and macromolecular impurities, and improve the efficiency of subsequent purification processes.
For example, in the treatment of erythromycin fermentation broth, membrane separation technology can replace traditional plate and frame filtration to retain mycelium and protein impurities in the fermentation broth. The permeate has high clarity, the efficiency of subsequent resin adsorption is increased by more than 30%, and resin pollution is reduced, extending its service life. The UF-membrane refining and impurity removal system developed by Bluewav Technology is designed according to the characteristics of biological fermentation broth, with an installed power of 2.2KW-30KW and a production capacity of 50-8000Kg/h, which can meet the fermentation broth impurity removal needs of enterprises of different scales.
(2) Refining and Purification of Traditional Chinese Medicine Preparations
The extract of traditional Chinese medicine preparations contains macromolecular impurities such as plant proteins, starches, tannins, and pigments. Traditional filtration methods easily lead to poor product clarity, insufficient stability, and short shelf life. Membrane separation technology (ultrafiltration membrane, nanofiltration membrane) can effectively separate impurities in the traditional Chinese medicine extract through molecular-level interception, retain effective active ingredients, and improve product purity and stability.
In the production of traditional Chinese medicine injections (such as Shuanghuanglian Injection, Aixiaoping Injection) and oral liquids (such as Xiao'er Qingre Zhike Oral Liquid, Huoxiang Zhengqi Liquid), membrane clarification and filtration technology can significantly improve product clarity, reduce the risk of adverse reactions, and extend the shelf life. Membrane separation technology does not require high-temperature treatment, avoids the destruction of effective components of traditional Chinese medicine, and achieves the dual goals of "high-efficiency purification + activity retention".
(3) Concentration and Desalination of Biological Products
Concentration and desalination are key links in the production of biological products such as blood products (albumin, immunoglobulin), peptides, and amino acids. The traditional evaporation concentration process has high energy consumption and is easy to cause denaturation of active ingredients. However, the reverse osmosis membrane and nanofiltration membrane concentration systems can achieve material concentration and desalination at normal temperature, with energy consumption only about 30% of that of the traditional process.
For example, in the concentration process of heparin sodium and animal protein, the membrane concentration system can quickly increase the material concentration, while removing salt and small molecular impurities to improve product purity. The NS/RS-membrane concentration system of Bluewav Technology has a working pressure of ≤2.0MPa and a temperature controlled at 5-45℃, which can achieve a production capacity coverage of 25-8000Kg/h, meeting the large-scale production needs of biological products.
(4) Sterilization and Aseptic Filtration
Biopharmaceutical products have extremely high requirements for microbial contamination control. The microfiltration membrane (pore size 0.1-1μm) in membrane separation technology can achieve efficient interception of microorganisms such as bacteria and viruses, replacing traditional high-temperature sterilization, chemical sterilization and other methods, and avoiding the destruction of product activity.
In the production of sterile products such as biological vaccines and injectable antibiotics, membrane sterilization and filtration technology can ensure that the microbial indicators of products meet the standards, while simplifying the production process and reducing costs. In addition, membrane elements can be repeatedly cleaned and regenerated, with a service life of 2-3 years, further reducing the operating costs of enterprises.
3. Application Advantages of Membrane Separation Technology in the Biopharmaceutical Industry
- High-Efficiency and Precise Separation: Membrane separation technology has a uniform pore size distribution, which can achieve molecular-level selective separation, effectively remove impurities, improve product purity, and meet the strict requirements of the biopharmaceutical industry for product quality.
- Green and Energy-Saving: It is a pure physical separation process that does not require the addition of chemical agents and has no secondary pollution; it operates at normal temperature with low energy consumption, which is in line with the green production trend of the pharmaceutical industry.

- Both Scalability and Flexibility: Membrane separation systems can be flexibly configured according to production capacity needs, and can be adapted from small-scale test, pilot test to industrial production. For example, the small and pilot-scale membrane experimental system (SMZ/SJM series) of Bluewav Technology is suitable for the R&D stage, and the large-scale membrane filtration/concentration system can meet the 10,000-ton level production needs.
- Reduction of Comprehensive Costs: Membrane elements can be reused with a long cleaning cycle, reducing the cost of consumable replacement; simplifying the production process, reducing labor and energy consumption, and improving the economic benefits of enterprises.
