Used for artificial membrane permeation in the ultrafiltration process. It is generally made of polymer materials such as cellulose acetate, cellulose acetate, polyethylene, polysulfide, and polyamide. Generally, various types of membrane modules such as tube type, plate type, roll type, capillary type, etc. are pre-made, and then multiple modules are assembled to increase the filtration area and facilitate maintenance.

The ultrafiltration membrane has an asymmetrical microporous structure and is divided into two layers: the upper layer is a functional layer, which has dense micropores and the function of intercepting macromolecules, and its pore size is 1-20nm; the lower layer has a support layer with a large through-hole structure, which increases The role of large film strength.
The functional layer is thin, and the water permeable flux is large. 

Generally, various types of components such as tube type, plate type, roll type, capillary type, etc. are made first, and then multiple components are assembled to increase the filtration area. The membrane ultrafiltration process is essentially a mechanical screening process, and the size of the pores on the membrane surface is the most important controlling factor. 

The solute (polymer or solution) that can be separated by the ultrafiltration membrane is a molecule with a size of 1-30nm. In addition to the characteristics of the membrane, the substances it rejects are also related to the shape, size, flexibility, and operating conditions of the substance molecules. Cellophane and nitrocellulose membranes are used in early ultrafiltration membranes.
