Seitz® IR Series
Depth Filter Sheets
For Distilled Spirits Filtration
Seitz IR series depth filter sheets were developed to meet theproduction needs and requirements of the distilled spirits
industry.

Description
A visually bright finished product free from visible particles is
one of the main objectives of spirits filtration. Components(C12-16 fatty acid esters, terpenes, proteins or their complex
compounds with metals and/or phenols) of some spirits may
precipitate if calcium ion levels are too high. Magnesium may
also cause precipitations in tannin containing spirits likewhisky and brandy. Standard filter sheets contain small
quantities of these extractable ions from the raw materials.
IR Series filter sheets undergo a proprietary treatment that
results in extremely low levels of extractable ions making
them the ideal solution for distilled spirits applications.
Features
Homogenous and consistent
media, available in multiple
grades
A combination of surface,depth and adsorptive
filtration

These figures have been determined in accordance with in-house test methods
and the methods of the Technical / Analytical Work Group within the European
Depth Filtration Association.
2The permeability was measured under test conditions with clean water at 20°C(68°F) and a Δp of 1 bar (14.5 psi).

The diagram below illustrates the release of calcium andmagnesium from the comparable standard filter sheet K100
and K100 IR into whisky during filtration.

Filtration Guidelines4
As the filtrate quality can be impacted by the filtration flow rate,
the following table provides guidelines for flux rate.
Flow Velocity L/m²/h (gal/ft²/h)

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 andwhite spirits high in fatty acids

250 – 400 (6.1 – 9.8)

Mg - K 100

Chill filtration of white spirits

400 – 600 (9.8 – 14.7)

Ca - K 100 IR

Please contact Pall for recommendations on your specific filtration process as
results may vary by product, pre-filtration and filtration conditions.

Calcium and Magnesium Release [mg/L]

To prevent dilution upon installation, a water rinse is notrecommended for sheet filters used in the spirits industry.
Product circulation for 10 to 15 minutes back to the feed tankhelps to distribute ions extracted at the beginning of filtration
to the entire batch reducing the overall risk of precipitation.

Application

Release of Ca and Mg
during Filtration of Whisky

15The use of ion-reduced water (deionized water) is highly
recommended for the reconstitution of distillates to single
strength.
