Membrane Filter:
Touch filtration is a precision separation technology that can achieve molecular-level filtration. It is a two-phase separation technology using the selective permeability of membrane pores. Using the pressure difference on both sides of the membrane as the driving force, the solvent, inorganic ions, small molecules, etc. pass through the membrane, while retaining particles and macromolecules.
Practical application:
1、Ultrafiltration: The so-called ultrafiltration is that under a certain pressure, when the solution containing small molecules passes through the surface of the supported membrane, the solvent and small molecule solutes will pass through the membrane, while the macromolecules will be intercepted and used as a concentrated solution. Recycle.
2、Nanofiltration: Nanofiltration is a membrane separation technology developed on the basis of reverse osmosis. The interception particle size of nanofiltration membrane is generally between 0.1 and 1 nanometer, the operating pressure is between 0.5 and 1 MPa, and the intercepted molecular weight is 200~1000, which has good separation performance for small organic molecules with a molecular weight of several hundreds in water.
3、Reverse osmosis: reverse osmosis can also be called high filtration. It is a reverse process of osmosis. By adding a pressure higher than the osmotic pressure on the liquid side to be filtered, the solvent in the original solution is compressed to the semi-permeable membrane. on the other side.
4、Microfiltration: Microfiltration is one of the membrane technologies that uses the static pressure difference as the driving force and uses the sieving effect of the membrane to filter and separate. The characteristics of the microfiltration membrane are the neat and uniform porous structure design. Under the action, the particles smaller than the membrane pores will pass through the filter membrane, and the particles larger than the membrane pores will be intercepted on the surface of the filter membrane, thereby achieving effective separation.
