With the development of membrane manufacturing technology, the uses of ultrafiltration have become more and more extensive. Currently, ultrafiltration membrane technology has been used in seawater desalination, reclamation of reclaimed water, pretreatment of reverse osmosis systems, condensate water treatment, and preparation of ultrapure water. Ultrafiltration is a membrane separation process with screening as the separation principle and pressure as the driving force. Compared with conventional pretreatment, ultrafiltration technology has the advantages of standardized design, low investment, wide uses of the ultrafiltration device, high output, no need for continuous dosing, high stability, less labor required, small floor area, high automation degree, and convenient operation.
