What are the types, shapes and sizes of ultrafiltration membranes used in household water purifiers?

Ultra-filtration membrane filtration is also a membrane separation process, ultra-filtration using a pressure-activated membrane, in the outside world under the action of the impetus (pressure) to retain the colloids in the water, particles and relatively high molecular weight of the material, and the water and small solute particles through the membrane of the separation process. Through the microporous screening on the membrane surface, substances with molecular weights of 3x10000-1x10000 can be retained. When the treated water passes through the membrane surface at a certain flow rate with the help of external pressure, water molecules and solutes with molecular weight less than 300-500 will pass through the membrane, while particles and macromolecules larger than the membrane pore size will be retained due to the screening effect, so that the water will be purified. In other words, when the water passes through the ultrafiltration membrane, most of the colloidal silica contained in the water can be removed, and at the same time, a large number of organic matter can be removed. That is, the water output of 1000L/H, as shown in the figure:

2, flat mouth ultrafiltration membrane, mainly used in 3 + 2 kitchen water purifier, the size of 10 inches.

3, socket type ultrafiltration membrane, size is 9 inch, 10 inch.

4, quick-connect ultrafiltration membrane, mainly used in chamber type ultrafiltration energy machine, there are American quick-connect and Korean quick-connect, size is 10 inches.

5, demonstration machine special ultrafiltration membrane, size is 75 * 330mm, mainly used for ultrafiltration demonstration machine.

6, the centralized ultrafiltration membrane, similar to the socket ultrafiltration membrane, the size depends on the water purifier, mainly used in the central water purifier.

7, composite cartridge ultrafiltration membrane, mainly used in the faucet above the water purifier, composed of ultrafiltration membrane + activated carbon.

Tips: the specific specifications of the ultra-filtration membrane to the actual measurement, can not be decided by the amount of water to buy replacement, the above picture is provided by Baidu Images, the above content is only the author's personal views, for reference only!
