HL Series
Water Softening NF Elements
The H-Series proprietary thin-film nanofiltration
membrane elements are characterized by an ap-
proximate molecular weight cut-off of 150-300 dal-
tons for uncharged organic molecules. Divalent and
multivalent ion rejection is dependent upon feed
concentration and composition.
HL Nanofiltration Elements are used for water sof-
tening, color removal, and reduction of THM for-
mation potential.

1 These elements are dried then bagged 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
