Membrane Separation Technology In Medicine Preparations
At present, membrane separation technology has been widely applied in the medical industry, especially the preparation of oral agents and injections of traditional Chinese medicines. Thus, customers need to know more details about this technology.
Firstly, membrane separation technology can be used to differentiate and concentrate on heat-sensitive substances in a normal temperature environment. It has a very low energy consumption rate while providing a high separation efficiency.
It could retain the active ingredients during the extraction process of the drug. Besides, it can maintain a superior environmental protection effect. It can realize the automatic separation of substances, which is easy for the operators to implement and carry out.
The filter membranes are easily contaminated, such as the blocked pores phenomenon or appearance of the formed adhesion layer. For the separation of traditional Chinese medicine, it is necessary to maintain the pore diameter of the medicine in the range of 1 to 5 nanometers.
Then, the medicine should be treated by medium filtration method, like the filter paper or talcum powder. The efficiency and quality of the separation can be greatly improved.
Meanwhile, the filter membrane could also be well protected. Moreover, to effectively alleviate the concentration polarization, the solute concentration on the surface of the membrane should be reduced. In the process of solving this problem, there are two kinds of methods to reduce the viscosity of the Chinese medicine liquid, magnetic stirring, and pulse flow method.
