Filtration is an ancient separation technology widely used in transportation, water treatment, chemicals, food and beverage production, fine chemicals, pharmaceuticals and biotechnology, power generation, paper making, Health, electronic and electrical industries.
The filter media used in surface filtration are mostly polymer membrane materials with a relatively regular pore structure and uniform pore size distribution, such as mixed Cellulose, polytetrafluoroethylene PTFE, nylon, polyethersulfone (PES) and polyvinylidene fluoride PVDF, etc. The surface filter medium has very precise cutoff pore size parameters. When the suspension flows through the membrane surface, the evenly distributed fine pores on the membrane only allow water and small molecular substances smaller than the cutoff size to pass, while the volume of the suspension is larger than the cutoff size. Nearly all substances with a pore size are trapped on the liquid inlet side of the membrane, achieving separation and concentration of the original solution. The characteristic of surface filtration is that it has a good interception effect and can intercept all particles larger than the pore size. However, the filtration capacity is limited and it is suitable for fine filtration. But when it comes to sterilization, you must use 0.22um sterilization filter membrane.
0.22um sterilizing filter membrane with a pore size of 0.22 microns is made of polytetrafluoroethylene suspended powder as raw material and uses a special One type of membrane prepared by biaxial stretching technology is a microporous membrane. This membrane can ensure that all impurities such as small bacteria are trapped, and at the same time has a larger flux. When the membrane pore size is smaller and the distribution is more uniform, the bubble point value of the membrane The higher the value, the better the interception effect. Products are widely used in filtration in medicine, food, bioengineering and other industries.
It is a 0.22um sterilizing filter membrane manufacturer that specializes in R&D, production and sales. The materials of the products produced by our company are all imported raw materials, with high uniformity, stable performance and good breathability. It also has high filtration efficiency and can meet the filtration efficiency level requirements of different levels of filters. Interested parties can enter the store for consultation and purchase!
