Tiefenfiltration
Depth filter
Thick and fibrous
High dirt holding
Membranfiltration
Thin single layer film
Low dirt holding
Cartridge filtration
Integrity testable
Much of the removal is not done on the surface but rather in the depth of a membrane filter, it’s not 0.45 defined pore size but rather a matrix,
Membrane filters are absolute since they remove guaranteed particles bigger than their pore size,
Depth filters - nominal, higher holding capacity but lower retention
0.45 micron removes all bacteria in wine and beer - so for our industry it’s sterilizing grade .
In France they don’t do so much membrane filtration when they do they use 0.65-1 micrometer. In Italy, Spain, USA, Australia 0.45
Almost no one can reliably tell the difference between 0.45 vs 0.65 filtered wine.
Brett with how many microns can you filter it out?
1 micron
Dead-end filtration
We’re running the wine at a 90 degree angle against the filter, building a filter cake
Sorbic acid
Against enzymes, mostly against yeasts and molds, only partly against bacteria, doesn’t work against lactic acid bacteria
Lactic acid bacteria can build Sorbinol - Geranienton -Fehler
