The ultrafiltration is a process of filtering a solution containing macromolecules or fine particles by using an ultrafiltration membrane with the aperture of 1 to 20nm to separate the macromolecules or the fine particles from the solution, which is called as ultrafiltration, and uses the pressure difference between two sides of the membrane as a driving force, and the ultrafiltration membrane as a filtering medium to enable micromolecule solutes and a solvent to pass through the ultrafiltration membrane with a certain aperture under a certain pressure, so that the macromolecule solutes cannot permeate and remain on one side of the membrane, thereby achieving the purposes of purifying, separating and concentrating the solution, and being mainly used for intercepting the macromolecule solutes.
The ultrafiltration membrane finishes the filtration process by taking the pressure difference between two sides of the membrane as a driving force, and under a full-flow filtration mode, some particles larger than the pore diameter of the membrane are accumulated on the surface of the membrane to cause the congestion of the ultrafiltration membrane, namely the filtration resistance is increased, so that the pressure difference between two ends of the membrane is also increased, the ultrafiltration membrane is damaged by the larger pressure difference and the accumulated substances on the surface of the membrane, and even the ultrafiltration membrane is broken and damaged, so that the ultrafiltration membrane loses the filtration function.
