elementary analysis ultrafiltration membrane How to save Ultrafiltration membrane manufacturer

With the sustainable development trend of environmental protection enterprises, more and more ultrafiltration membranes are used. Ultrafiltration membranes are generally used to separate, concentrate and purify biopharmaceuticals, pharmaceutical products and food industries; In addition, it is also used as terminal equipment solution equipment in blood and night solution, wastewater treatment and ultrapure water system preparation. Before the ultrafiltration membrane is applied, it usually penetrates into the maintenance solution for sealing preservation to prevent the wet membrane from collapsing and shrinking after drying, which will damage the membrane structure engineering and reduce the water flux. Next, I will give you a brief and detailed introduction to the preservation method of ultrafiltration membrane.

1. Ultrafiltration membrane components must always be kept in a dark place, the storage temperature should not exceed 35 ℃, and the sun should be prevented immediately. After pressure test, appropriate drugs shall be added or timely flushing method shall be selected for storage.

2. Short term storage: the ultrafiltration membrane manufacturer suggests that if the ultrafiltration membrane is out of use (less than 10 days), it should solve the sterilization backwash of the ultrafiltration membrane once, add 15ppm (ml/L) HY-240 pesticide bactericide to the backwash water, and then close the water valve, drain valve and regulating valve of the ultrafiltration membrane, so as to maintain the sealing and sterilization effect of the ultrafiltration membrane.

3. Long term preservation: if the ultrafiltration membrane is out of service for a long time (more than 10 days), the ultrafiltration membrane manufacturer points out that the ultrafiltration membrane should first be sterilized and backwashed once, and then be sealed after HY-310 maintenance solution is introduced into the ultrafiltration membrane.

The above is a common preservation method for ultrafiltration membrane. In addition to proper preservation, ultrafiltration membrane must be cleaned on time to maintain a certain membrane flux and increase its service life. The cleaning method is generally determined according to the characteristics of the membrane and the characteristics of the solution solution.
