Dairy Ultra UF Series
Ultrafiltration – Superior Flux
Exclusively used for food related processes requir-
ing stringent sanitary procedures, the typical appli-
cations include whey and milk fractionation where
the Dairy Ultra UF membrane displays exceptional
process flux and protein retention due to a specific
membrane structure while being easily cleanable.
The Dairy Ultra UF membrane features a 10,000 Da
molecular weight cut-off and has great perfor-
mance in acid and sweet whey applications.
Element features include:
 High protein rejection
 High process flux
 Durable membrane
 Patented Durasan* Cage outer wrap
 Polysulfone parts and standard feed spacers
The Dairy Ultra UF elements comply with:
 FDA Regulations relevant sections of 21CFR
 EU Framework 1935/2004/EC

1 Clean water flux (CWF) is the rate of water permeability through the membrane
after cleaning (CIP) at reproducible temperature and pressure. It is important to
monitor CWF after each cleaning cycle to determine if the system is being
cleaned effectively. CWF can vary ±25%.
