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

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
