Here, the analysis of the characteristics of the membrane separation technology is mainly combined with its performance in the field of pharmacy, and is summarized in the following four points: The first is the simple flow of the process. Membrane separation technology simplifies the flow of the pharmaceutical industry և improves efficiency. Product quality guarantee is implemented. Membrane separation technology can ensure the purity of drugs և ensure that drugs can fully affect their effects. The third point is the low energy consumption, as there will be no chemical reactions in the separation process, using the membrane separation technology. , so it is environmentally friendly. Higher, it can also avoid pollution and waste. The fourth point is the low operating costs.
