With the increasingly common development of ultrafiltration membrane technology, ultrafiltration technology has been widely used in food enterprises, beverage industry production, dairy products and other industries in the era, as well as in microbial fermentation, biotechnology, pharmaceutical chemicals, biological products and other industries. At this stage, ultrafiltration membrane filter is playing an increasingly important role in social development, providing users with a lot of convenience, and is deeply loved by new and old customers. Next, I will take you to find out how to protect the ultrafiltration membrane filter after the shutdown.

1. ultrafiltration membrane filter shutdown operation.

Before shutdown, the uf membrane module needs to be physically cleaned, and then the actual shutdown operation can be performed. Specific steps are as follows:

When the system uses the booster pump as the filtration power device, first open the concentration inlet valve and the ultrafiltration gate valve to minimize the system pressure difference and transmembrane pressure difference, then stop the centrifugal pump and disconnect the switching power supply. After stopping the pump, close the gate valves on the seepage side and the permeate side of the membrane to keep it moist. Once dry, parts will inevitably be damaged.

2. Maintenance of uf membrane module.

After the ultrafiltration membrane filter is shut down, remember to keep the membrane components moist, pay attention to the antibacterial and mildew removal of the membrane, and pay attention to cold protection in winter.
When the ultrafiltration membrane filter is out of use for a long time, the mechanical equipment must be fully cleaned, disinfected and sterilized. Cleaning includes physical cleaning and organic chemical cleaning.
Nowadays, with the increasing development of ultrafiltration membrane technology, the application of ultrafiltration devices is very common, and it is widely used in various fields of social production and daily life, providing huge economic benefits for the rapid development of various fields. work to ensure that the equipment can operate normally in the later stage without failure.
