CD Series High Rejection 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 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).

Note

Average salt rejection after 24 hours operation. Individual flow rate may vary +25%/-15%.
Testing conditions: 2,000ppm NaCl solution at 425psig (2,930 kPa) operating pressure, 77°F, pH 6.5 and 15% recovery.

Note

These elements ship dry.
