The over-exploitation of groundwater and the massive pollution of water resources have brought serious crises to human water safety. In order to better optimize the allocation of water resources and improve the utilization of water resources, filtration products such as ptfe sterilizing filter membranes are Appeared, this material has alleviated the crisis of water shortage to a great extent.
PTFE sterilization filter membrane has strong hydrophobicity, chemical resistance, waterproofness and low wind resistance, and can achieve high dust removal efficiency. For some extremely small particles with a diameter of 0.1um-0.3um, the filtration level Can reach H13-U16.
In addition, biaxially oriented film can undoubtedly achieve ultra-low emissions in intercepting various types of dust generated during the production process of the company, and it fully complies with current environmental protection standards.
Many pharmaceutical companies can basically have dedicated filter elements for each variety, store them separately, and use various methods to mark them, which is relatively safe and easy to check and use.
In order to ensure the filtration effect of the sterilizing filter, the integrity of the filter needs to be tested before and after use to ensure that its filtration is effective.
The current main integrity testing methods include forward flow, bubble point and water intrusion testing methods, and the bubble point test is currently the main integrity testing method.
Different chemicals have different properties, and the bubble point data obtained by wetting the same filter using different media may be different to varying degrees.
