Request Information
The C-Series family, a triacetate/diacetate blend, has a higher flux and better mechanical stability than standard cellulose acetate. C-Series elements offer a lower per element cost and increased chlorine resistance compared to thin-film elements.

CD High Rejection Elements are used for brackish water desalination and process stream concentration at 425 psig operating pressure (2,930 kPa).
