The Correct Method for Storing Hollow Fiber Ultrafiltration Membranes
Hollow fiber ultrafiltration membranes have found widespread application in industrial fields, playing a crucial role in separation, concentration, and purification processes across sectors such as biopharmaceuticals and the food industry. They are also commonly used in wastewater treatment systems and as final-stage treatment units in ultrapure water production. Before use, hollow fiber ultrafiltration membranes are typically immersed in a protective solution to ensure proper sealing and preservation. This prevents the wet membrane from dehydrating, which could otherwise lead to shrinkage, narrowing of membrane pores, structural damage, and a subsequent decline in water flux. Below, we’ll briefly introduce two common methods for preserving these membranes.

Hollow-fiber ultrafiltration membrane It has been widely applied in the industrial sector, playing a key role in processes such as separation, concentration, and purification in biopharmaceuticals, the food industry, and more. It is also used as a final-stage treatment device in wastewater treatment and ultrapure water production systems. Hollow-fiber ultrafiltration membrane Before use, the membranes are typically immersed in a protective solution and stored sealed to prevent dehydration when wet, which could cause shrinkage, reduce pore size, damage the membrane structure, and ultimately lower water flux. Now, let me briefly introduce this to you below. Hollow-fiber ultrafiltration membrane Two methods for preservation.
1 "· Short-term storage: At Hollow-fiber ultrafiltration membrane Addition to disinfectant and backwash water 15 ppm (ml/L) HY-240 Disinfectant—shut off the inlet valve, drain valve, and control valve of the ultrafiltration membrane, and maintain… Hollow-fiber ultrafiltration membrane The sealing and sterilization effectiveness, such as less than 10 The brief use of time has come to a halt.
2 • Long-term storage: Hollow-fiber ultrafiltration membrane When ceasing use for an extended period (10 More than one day ) First, sterilize and backwash, then inject into the membrane. HY-310 Protective liquid, store in a sealed container.
3、 Hollow-fiber ultrafiltration membrane Components should always be kept in a dark place. 35 Avoid direct sunlight exposure at the temperatures mentioned above. If storing after watering, be sure to add appropriate chemicals or use a regular rinsing method.
Besides these two correct methods of preservation Hollow-fiber ultrafiltration membrane In addition to the method used, the ultrafiltration membrane must also be cleaned regularly to maintain adequate membrane permeability and extend its service life. The cleaning method is typically determined based on the membrane's characteristics and the properties of the feed liquid being processed.
