GC 12×40

Liquid-phase granular activated carbon
GC 12×40 is a Re-agglomerated virgin activated carbon which is granular in form. Made from the finest grades of bituminous coal, 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. NSF certified, it is suitable for drinking water and food grade applications.
