Acid-washed granular activated carbon for pH stabilization

GC 8 x 30 AWPH is a virgin acid washed activated carbon which is specially treated to reduce pH rise in the start-up of new activated carbon beds.   Made from the finest grades of re-agglomerated 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 a longer life expectancy. Manufactured at an NSF/ANSI certified facility, it is suitable for drinking water and food grade applications.

Wet activated carbon removes oxygen from air causing a severe hazard to workers inside carbon vessels. Confined space/low oxygen procedures should be put in place before any entry is made. Such procedures should comply with all applicable Local, State and Federal guidelines.
