What are the precautions for cleaning ultrafiltration membranes in biopharmaceutical pure water equipment? Author: With the phenomenon of severe water pollution, bio-pharmaceuticals are using bio-pharmaceutical water equipment to improve water quality and bio-pharmaceutical water equipment ultrafiltration membranes are the core elements of the device, it is used in the bio-pharmaceutical water equipment in端处理装置。 End processing device. Since the ultrafiltration membrane is a porous material that removes impurities in the water by means of physical retention, the ultrafiltration membrane should be cleaned regularly to ensure the working efficiency of the ultrafiltration membrane and prolong the service life of the ultrafiltration membrane. The following editor introduces the cleaning steps of the ultrafiltration membrane. 1. Prepare the cleaning solution. 2. Input the cleaning solution at a low flow rate: first mix the cleaning solution with the cleaning water pump, and use a low flow rate when preheating the cleaning solution. 3. Circulation: After the raw water is replaced, the cleaning fluid should appear in the concentrated water pipeline. Let the cleaning fluid circulate to clean the water tank and keep the temperature of the cleaning fluid constant. 4. Soaking: Stop the operation of the cleaning pump, and let the membrane element be completely immersed in the cleaning liquid. 5. High-flow water pump circulation: high-flow can flush out the pollutants washed by the cleaning liquid. 6. Flushing: Cleaning the ultrafiltration membrane in time can maintain the working efficiency and service life of the membrane, and the correct cleaning method can save time and reduce the damage of membrane elements during the cleaning process.
