Seasoft* Series
NF Elements for Sulfates and Hardness Removal from Seawater
NF Applications for Seawater
NF has the unique ability to selectively reject ions:
Rejection of anions with more than one negative
charge
Rejection of cations depending on shape and size
Rejection of organic if molecular weight is >200-
300 Daltons
At least 80% of water hardness is removed with
low operating pressure and high flux.
Seasoft HR/HF Elements:
Fouling-Resistance Seasoft elements prevent:
Scale formation by removal of hardness and sul-
fates
Fouling by removal of turbidity and bacteria on
down stream equipment.
Seasoft HR for Applications Requiring:
High Hardness Rejection 95%+
High Sulfate Rejection 99%+
Sodium Chloride Rejection 20-30%
Seasoft HF for Applications Requiring:
High Flux at Low Pressure
High Hardness Rejection 95%+
High Sulfate Rejection 99%+
High Sodium Chloride Passage

The element diameter (dimension C) is designed for optimum performance in GE
Water & Process Technologies pressure vessels. Others pressure vessel dimension
and tolerance may result in excessive bypass and loss of capacity.
