[0022] Embodiment (1):
[0023] A dry state preservation method for an ultrafiltration membrane component. The preserved ultrafiltration membrane component is made of internal pressure polysulfone material, and the molecular weight cut-off is 67,000. at water temp 25 o C. Under the operating pressure of 0.1MPa, the ultrafiltration water flux is 150LMH (liter / square meter / hour).
[0024] Before packaging after production, install the ultrafiltration membrane module on a small ultrafiltration equipment, configure a sufficient amount of sodium hypochlorite sterilization solution, the concentration is 100ppm (calculated as available chlorine), and run at room temperature for 5 minutes under the operating pressure of 0.1MPa , sterilize the components.
[0025] The ultrafiltration membrane module was fully cleaned with ultrafiltration water at room temperature, and the operating pressure was 0.1MPa for 2 hours.
[0026] Remove the ultrafiltration membrane module from the equipme...

Example Embodiment
[0032] Embodiments (2), (3), (4) The actual operation refers to Embodiment (1), and the specific detailed parameters are described in Table 1, as follows.
[0033] Table 1. Implementation parameters of dry-state membrane preservation method for ultrafiltration membrane modules
[0034]
[0035] Note*: At water temperature 25 o C, test with ultra-filtered water under the operating pressure of 0.1MPa.
[0036] The ultrafiltration membrane module operated with the above parameters has no change in ultrafiltration performance after testing. Ultrafilters are effectively preserved.
