How many years can ultrafiltration membrane be used? The service life of different filter membranes is different. Generally, the ultrafiltration membrane can be used for three years. Of course, it also depends on the use. Different water quality in different places may have different service life. Besides regular forward flushing, backwashing and chemical cleaning, maintaining a low working pressure, increasing pre filtration and improving inlet water quality will also greatly prolong the service life of ultrafiltration membrane.
How to maintain the ultrafiltration membrane?
1. The ultrafiltration membrane shall be cleaned regularly
We all know that the filter element of the water purifier needs to be cleaned, and so does the ultrafiltration membrane. Otherwise, the service performance and service life of the ultrafiltration membrane will be affected. Regular cleaning can also maintain the good permeability of the ultrafiltration membrane. The cleaning method will generally be determined according to the properties of the ultrafiltration membrane and the properties of the treated material. However, in most cases, it is cleaned with clean water, and then cleaned with different chemical agents according to different situations
2. Introduction to physical cleaning method
In fact, the cleaning of ultrafiltration membrane is very simple, and the physical cleaning is very simple. For the removable ultrafiltration membrane whose membrane hole is not particularly small, generally, it can be directly disassembled and wiped and washed with soft material; According to the size of the membrane pipe diameter, a suitable sponge ball can be selected and wiped and washed with special equipment, and this method can be used repeatedly; Cleaning the ultrafiltration membrane with hot water at 30-40 ℃ can remove some viscous substances or hot-melt impurities;
3. Keep it in the protective solution after use
The ultrafiltration membrane shall be preserved after use, generally in the protective solution. The purpose of this is to prevent the shrinkage of the ultrafiltration membrane after dehydration, which will damage the membrane structure and reduce the permeability.
