Fact Sheet
Dairy PT Series
Ultrafiltration – Superior Protein Retention
The Dairy PT Series of polyethersulfone ultrafiltra-
tion membrane elements are characterized by a
5,000 molecular weight cut-off. These elements are
typically used for protein concentration up to 30%
solids from milk, whey and gelatin, when protein
retention is key.
The elements feature a Durasan* patented outer-
wrap, a selection of feed spacers, and polysulfone
parts.
The Dairy PT elements comply with:
 FDA Regulations relevant sections of 21CFR
 EU Framework 1935/2004/EC

1 These elements are bagged dry before shipping.
2 Internal diameter unless specified OD (outside diameter).
3 The element diameter (dimension C) is designed for optimum performance in GE
Water & Process Technologies pressure vessels. Other pressure vessel dimension
and tolerance may result in excessive bypass and loss of capacity.
