CE Series
Brackish Water RO Elements (Cellulose Acetate)
GE Power Water & Process Technologies
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 concentration.

1 These elements are dried then bagged before shipping, unless specified WET.
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.
