GC 12x40AW Activated Carbon

Acid-Washed Granular Activated Carbon

GC 12x40AW is a virgin acid washed activated carbon which is granular in form. Made from the finest grades of bituminous coal and then acid washed, it is ideal for many liquid phase applications including the removal of organics from water streams. Its superior adsorptive capacity and low level of impurities make it cleaner than most other carbons and gives it longer life expectancy.  Manufactured at an NSF/ANSI standard certified facility, it is suitable for drinking water and food grade applications.
