What are the application areas of membrane separation

The application fields of membrane separation technology are very wide, including water treatment, food processing, biotechnology, chemical industry, pharmaceutical industry, etc. ‌

In the field of water treatment, membrane separation technology is widely used, mainly in seawater desalination, wastewater treatment, and drinking water purification. For example, using reverse osmosis membranes to treat seawater can remove harmful substances such as salt and microorganisms, thereby obtaining clean fresh water. In addition, membrane separation technology can also be used for wastewater treatment, which can remove harmful substances from wastewater and obtain reusable water resources.

In the field of food processing, membrane separation technology is also widely used. For example, in the production of dairy products, protein, fat and other components in lotion can be separated through membrane separation technology, so as to produce high-quality dairy products. In addition, membrane separation technology is also used in fields such as juice processing and beer production for processes such as separation, concentration, and dehydration.

In the field of biotechnology, membrane separation technology is also widely used. In biopharmaceuticals, membrane separation technology can be used to separate and purify biomolecules such as proteins, enzymes, antibodies, etc. In addition, membrane separation technology is also used in bioreactors to separate and recover biomolecules, thereby improving the efficiency and yield of the reactor.

In the field of chemical engineering, membrane separation technology is also widely used. For example, in the petrochemical industry, membrane separation technology is used for processes such as separation, concentration, and dehydration to improve the purity and quality of petrochemical products. In addition, membrane separation technology is also used in organic synthesis to separate and purify organic compounds, thereby improving their purity and yield.

In the pharmaceutical industry, membrane separation technology has been applied for more than 30 years. Half of the existing pharmaceutical products are synthesized using biotechnology, and the production of amino acids, vitamins, and enzyme preparations cannot be separated from membrane separation technology. The application of membrane separation technology in this field includes the preparation of medicinal purified water, the production of injections, biopharmaceuticals, the preparation of oral liquid preparations, and the extraction and separation of active ingredients in traditional Chinese medicine.

In summary, membrane separation technology has a wide range of applications, covering almost every important field from water treatment to food processing, from biotechnology to chemical engineering, and pharmaceutical industry.
