The following total calcium and magnesium release per m2 filter sheet at a flow velocity of 500 L/m2/h (12.3 gal/ft2/h) was calculated during this filtration run:
Sheet |
Calcium mg/m2 (%) |
Magnesium mg/m2(%) |
K 1003 |
667 (100) |
192 (100 |
K 100 IR |
146 (22) |
68 (35) |
3The K 100 is the comparable standard sheet to the K 100 IR with regard to the material composition.
Quality
- Filter sheets produced in a controlled environment
- Manufactured according to ISO 9001:2015 certified Quality Management System
The use of ion-reduced water (deionized water) is highly recommended for the reconstitution of distillates to single strength.
To prevent dilution upon installation, a water rinse is not recommended for sheet filters used in the spirits industry. Product circulation for 10 to 15 minutes back to the feed tank helps distribute ions extracted at the beginning of filtration to the entire batch, reducing precipitation's overall risk.
Filtration Guidelines4
As the filtrate quality can be impacted by the filtration flow rate, the following table provides flux rate guidelines.
Application |
Flow Velocity L/m2/h (gph/ft2) |
Particle filtration of brown spirits |
500 – 700 (12.3 – 17.2) |
Particle filtration white spirits |
700 – 900 (17.2 – 22.1) |
Chill filtration of brown spirits and white spirits high in fatty acids |
250 – 400 (6.1 – 9.8) |
Chill filtration of white spirits |
400 – 600 (9.8 – 14.7) |
