Types of activated carbon filter media, with various particle sizes, base materials and activity maybe selected for pressure drop considerations and application parameters including type of contaminant and concentration. 

Traditionally, coal-based carbon filter media have been preferred as they provide excellent performance for contaminants and a broad range of concentrations.  Coconut carbon filter media have generally performed well with low boiling point, low molecular weight compounds at lower concentrations. Wood based carbon media offer superior decolorization properties.

The smaller mesh sizes are more suitable for units with lower flow rates or where it is desired to compress the active adsorption zone while the larger mesh sizes offer better pressure drop characteristics or better yields in a reactivation service cycle. 

Activity gives an indication of the capability of the particular adsorbate to provide surface loading . Higher values generally indicate a greater capability to provide surface loading. 

All virgin liquid phase activated carbon filter media are capable of producing non-detectable effluent quality for adsorbates which are cost-effectively adsorbed.  Reactivated carbon filter media are available for application where lower capacity and less stringent effluent quality will permit better cost-efficiency.
