GC 20×50

Granular Activated Carbon

GC 20×50 is a 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 wastewater streams. Manufactured at an NSF/ANSI standard certified facility, it is suitable for drinking water and food grade applications.
