Where Coal Based GAC is used
Typical applications and process selection checks.
-
Start with contaminant size, liquid or gas conditions and bed design before choosing an iodine or CTC target.
-
Select mesh against vessel screens, flow rate, pressure drop and any backwash or regeneration procedure.
-
Use washing, pH and ash limits when mineral carryover or downstream purity is important.
-
For VOC service, add CTC, butane activity or a contaminant-specific test instead of relying on iodine value alone.

Coal Based GAC sourcing questions
Answers use the same values as the tables on this page.
How should coal based GAC be selected?
Selection starts with the liquid or gas conditions, contaminant class, bed design, mesh and required adsorption index. Iodine value alone does not define application performance.
Can acid-washed coal based GAC be produced?
Acid washing, water washing, controlled pH and lower-ash specifications can be reviewed. Customized MOQ and lead time depend on the requested values.
What documents are supplied?
TDS and SDS can be supplied during quotation, and a batch COA can be supplied for each production or shipment batch.
