Meineng UF-1020E ultrafiltration membrane is an ultrafiltration membrane product with hollow fiber structure, which has a large filtration area and high filtration efficiency, and can achieve effective separation at lower pressure. The energy consumption in the separation process is low, which is conducive to energy saving and emission reduction. It is widely used in water treatment, food industry, pharmaceutical industry and biotechnology. Below, the blue film water treatment will introduce to you under what circumstances it needs to be replaced.
When the ultrafiltration membrane needs to be replaced:
1.Filtration effect decreases: When the filtration effect of Meineng UF-1020E hollow fiber ultrafiltration membrane decreases significantly and cannot meet the requirements of use, it is necessary to consider replacing the ultrafiltration membrane with a new one. This is usually caused by a blockage of the pores on the membrane surface, or a change in the physical properties of the membrane itself. Changes in the quality of the inlet water may also affect the filtration effect of the ultrafiltration membrane, if the influent water quality can not meet the requirements of use, the pore size of the ultrafiltration membrane is prone to pollution and blockage.
2.Physical damage of the membrane: If the physical properties of the ultrafiltration membrane change due to external factors such as mechanical shock, high temperature, chemical corrosion, etc., such as rupture and deformation, it is necessary to replace the ultrafiltration membrane with a new one.
3.Expiration of membrane life: Meineng UF-1020E hollow fiber ultrafiltration membrane has a certain service life, usually about 3 years. After this time, even if the filtration effect of the membrane does not decrease significantly, a new ultrafiltration membrane should be considered to ensure the normal operation of the equipment.
4.Increased maintenance costs: If the maintenance cost of the ultrafiltration membrane is getting higher and higher, such as the number of cleanings increases, the cleaning effect decreases, or more cleaning agents need to be used, it also means that the performance of the membrane has decreased and a new ultrafiltration membrane needs to be replaced.
5.The pressure difference of the membrane is too large: when the pressure difference between the inlet pressure and the outlet pressure of the ultrafiltration membrane is too large, which is beyond the tolerance range of the membrane, it will lead to damage to the membrane and need to replace the ultrafiltration membrane.
In general, the replacement of Meineng UF-1020E ultrafiltration membrane needs to be comprehensively considered according to its use, filtration effect, physical state and maintenance cost. At the same time, the process of replacing the ultrafiltration membrane also needs to be carried out in strict accordance with the operating procedures to ensure the normal operation of the equipment.
