“Filtration” refers to the separation between tiny solid particles or aerosol particles in fluids (gases and liquids) and the fluid. The device used to achieve this separation is filtration Device, the filtration device needs to be installed with a filter membrane. Only when the Teflon microporous filter membrane has a high filtration efficiency can the fluid become pure or sterile. “Purification” is also a kind of separation, but general purification devices, such as cyclone separators, vortex tube separators, gas-liquid separators, etc., do not have filter membranes. They rely on scientific and reasonable mechanical structure design and can only separate larger particles. Generally, the purification accuracy is above 1μm. In fermentation industries such as biopharmaceuticals, air filtration and purification technology are widely used in the preparation of sterile air systems.
The sterile air filters used in the fermentation industry have experienced a transition from low efficiency and high energy consumption to high and low energy consumption. The process of transformation. When the filter media of the main air filter and sub-filters are cotton and activated carbon, it is called cotton carbon + cotton carbon filter; when the filter media of the main air filter and sub-filters are cotton, activated carbon and glass fiber, It is called cotton carbon + laminated plate filter; when the filter media of the main air filter and sub-filter is glass fiber or metal composite membrane, it is called glass fiber + metal membrane filter; when the main air filter and sub-filter are When the filter medium is glass fiber or Teflon microporous filter membrane, it is called a pleated membrane + polymer membrane filter.
The currently independently developed Teflon microporous filter membrane series is the core material of bacterial filters and has hydrophobicity and affinity. Two categories of water-based. It is widely used in medicine, food, beverage, beer, chemical and other industries, such as filtration of sterile raw materials and medicinal liquid bacteria in the pharmaceutical industry, filtration of liquor, beverages, wine, fruit wine, etc. in the food industry, and organic solvents in the chemical industry. , various alcohols, chemical reagents, etc. filtration.
