Many users are concerned about the service life of hollow fiber ultrafiltration membrane, so how long is its service life? Under normal circumstances, its service life can reach 5-8 years.
The service life of the membrane is related to the cleaning of the membrane during use. The membrane can always maintain a good flux, improve production efficiency, naturally extend the service life of the membrane, and reduce the frequency of membrane replacement.
1. The gas in the ultrafiltration membrane equipment must be evacuated, otherwise when the equipment system is started, the gas will form a hollow fiber ultrafiltration membrane and damage the membrane element.
2.
