Dairy Ultra UF Series
Ultrafiltration – Superior Flux
Exclusively used for food related processes requiring stringent sanitary procedures, the typical applications 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 performance 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:

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%.
