CG Series
High Flux 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. C-Series elements
offer an increased chlorine resistance compared to
thin-film elements.
CG High Flux Elements are used for brackish water
desalination and process stream concentration.

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