[0002] Ultrafiltration membrane is a polymer semipermeable membrane used in the ultrafiltration process to separate polymer colloids or suspended particles of a certain size from the solution. Its working principle is to use micropores and microscopic channels to separate suspended matter, organic matter, heavy metal ions and other impurities in water by physical interception, while retaining minerals and trace elements that are beneficial to the human body. Ultrafiltration membrane technology is widely used in the field of water treatment.
