The Principle And Application Of Ultrafiltration Membrane Equipment

An ultrafiltration membrane is a microporous filtration membrane with a pore size range of 0.001 to 0.1 microns. Its working principle is to drive the solution by pressure difference, so that small molecule substances and solvents can pass through the membrane, while macromolecule substances and suspended matter are retained.

An ultrafiltration membrane device usually consists of a membrane module, a pump, pipelines, and a control system. When in use, the solution to be treated enters the membrane module, and under the action of pressure, water and small molecule substances pass through the membrane, while macromolecule substances and suspended matter are retained, thereby achieving the purification, separation or concentration of the solution.

The application of ultrafiltration membranes is very extensive. In the field of water treatment, it can be used to remove suspended matter, colloid, microorganisms, and macromolecule organic matter in water, improving the quality of water. In the field of biomedicine, ultrafiltration membranes can be used for the separation and purification of biological macromolecules such as proteins and enzymes. In addition, ultrafiltration membranes also have important applications in the food industry, chemical industry, and other fields.

In short, ultrafiltration membrane technology, with its high efficiency, energy saving, and environmental protection advantages, has become an important means in modern separation technology, and has contributed to the development of various fields.
