Overview of Membrane Separation Technology Time:2018.03.23
     Membrane separation technology is considered to be the most promising for the end of the 20th century to the middle of the 21st century, and it may even lead to an industrial revolution. It has become a research hotspot in all countries in the world. Membrane separation, as a newly developed high-tech separation technology, has expanded its application fields and has been widely used in the chemical, food, water, industrial, pharmaceutical, environmental protection, biotechnology, energy engineering and other areas, and has played a huge role.
   The study of membrane separation technology in China began with the study of ion exchange membranes in the 1960s. From the reverse osmosis technology in the 1960s to the pervaporation technology in the 1990s, membrane separation technology in China has developed rapidly. After decades of efforts, China's membrane separation technology has successfully developed a number of achievements that have practical value, approach or reach international advanced level, such as inorganic membrane reaction separation technology.

Membrane separation technology principle and advantages
   Membrane separation refers to the use of a semipermeable membrane as a barrier layer, with the aid of the membrane's selective permeation, to separate and purify different components of the mixture under the influence of energy, concentration, or chemical potential difference. Due to the different membrane pore size in the semi-permeable membrane, certain components can be allowed to pass through the membrane while other components are retained in the mixture to achieve a certain separation effect. The use of membrane separation technology for separation has the following advantages: the membrane separation process is relatively simple, at the same time easy to operate, compact structure, low maintenance cost and convenient, easy to automatically control; membrane separation process generally does not involve phase change, no secondary pollution and energy Lower consumption; membrane separation process can be operated at room temperature or low temperature, suitable for concentration and separation of heat-sensitive substances (enzymes, drugs); membrane separation process has considerable selectivity, applicable to a wide range of objects, can separate particles visible to the naked eye It can also separate ions and gases; the process can be operated continuously at room temperature, the equipment can be easily scaled up, the membrane can be specially formulated, and the appropriate membrane can be selected to obtain a higher recovery rate; the membrane separation processing system can be cycled in a closed system This prevents contamination of the outside world; no external chemicals are added during the process, and the permeate can be recycled, reducing costs and reducing environmental pollution.
    Because the membrane separation technology has the above advantages, it is a highly efficient separation method in the modern bio-chemical separation technology and can completely replace the traditional separation technology of filtration, adsorption, evaporation, condensation, etc., so the membrane separation technology in the bio-chemical separation project It plays a big role.
