Where Coconut Shell GAC is used
Typical applications and process selection checks.
-
Match mesh distribution to the vessel, retaining screens, backwash conditions and pressure-drop limit.
-
Use iodine value as one pore-structure reference, then add CTC or an application test when gas-phase performance matters.
-
Specify hardness, ash, pH and washing requirements for repeated handling or higher-purity water service.
-
Confirm the grade with the actual water, gas or precious-metal test rather than raw material name alone.
