When correctly installed, Parker’s final stabilization filter range guarantees product quality and stability. However, throughout the beverage manufacturing process, there are several opportunities for damage to occur and threaten the integrity of installed membrane filters.
A non-integral filter cannot guarantee your desired beverage quality. Integrity testing is a vital tool to ensure your final stabilization filters are free from damage and capable of producing a beverage that is free from spoilage organisms and microbiological contamination.
Visual inspection is no true indicator of filter integrity. Integrity testing interrogates the pore structure of the membrane layer itself and is correlated to the destructive bacterial challenge. All of Parker’s BEVPOR filters are correlated to bacterial challenge. If the filter passes the outlined integrity testing values found in the product datasheet, it is guaranteed to pass the bacterial challenge.
Benefits of modern integrity testing procedures.
Semi automated integrity testing with Parker's testing units has the following benefits:
- Fast and easy to set up - minimal down time during testing
- More accurate than manual pressure decay tests
- Programmable for various system sizes and micron ratings
- Data logging adds traceability and allows for data trending
Regular integrity testing is vitally important when cleaning/regenerating filters with harsh chemicals such as Sodium Hydroxide (caustic wash). Clean-in-place (CIP) is high risk for causing damage to filtration membranes. CIP regimes are critical for long filter lifetime and when partnered with routine integrity testing, it is a best practice combination to ensure filter performance and product quality.
