CE Series
Brackish Water RO Elements (Cellulose Acetate)
The C-Series family, a triacetate/diacetate blend,
has a higher flux and better mechanical stability
than standard cellulose acetate. CA-Series elements
offer an increased chlorine resistance compared to
thin-film elements.
CE Brackish Water Elements are used for brackish
water desalination and process stream concentra-
tion.

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
pressure vessels. Other pressure vessel dimension and tolerance may result in
excessive bypass and loss of capacity.
