DESCRIPTION
Explore description details to support your evaluation.
Coal-Based Granular Activated Carbon — large-scale industrial treatment where cost per cubic metre matters. Sanniu Carbon supplies this grade as a granular form, produced on our own activation lines and tested batch by batch.
Typical duty: municipal and industrial wastewater, flue gas treatment, deodorisation, solvent recovery. Screened granules for fixed beds and continuous columns, with the hardness to survive backwashing.
The coal-based series is characterised by a graded pore distribution with high strength and acid-alkali resistance. Reference values for the series range from 500-1100 mg/g iodine value, 650-1000 m2/g BET surface area, 35% or higher CTC adsorption and 20% or lower ash, produced by physical or chemical activation. The agreed specification for your order is confirmed per batch.
Send the medium to be treated, the flow rate or concentration, the target specification and the required particle size. We confirm the grade and the agreed specification plan before quotation, and a 1-5 kg sample is available for evaluation.
Granular carbon suits fixed beds and continuous columns: the mesh range sets both the pressure drop and the contact time, so specify the range your vessel is designed for. Backwashing is normally tolerated because of the hardness of the material. Watch for a rising outlet concentration, a colour or odour change, or an increasing pressure drop. Any of these indicates the bed is loading up; arrange a test or a replacement before the outlet goes out of specification. Thermal regeneration and acid washing are the usual recovery routes.
Values in the specification table follow the series reference ranges and are confirmed per batch. Iodine value and methylene blue adsorption are reported in mg/g, CTC adsorption, hardness and ash content in %, bulk density in g/cm3 and particle size in mesh. Test reports name the sample tested and the method used.

What a buyer can check before placing an order.
Five material series from one supplier
Coal-based, coconut shell, wood-based, nutshell and bamboo activated carbon are produced and exported directly, so different filtration duties can be covered without splitting the order across suppliers.

PACKAGING
Explore packaging details to support your evaluation.
Standard bulk packing options for coal-based granular activated carbon, with batch documentation provided for each shipment.
PROCESS
Explore process details to support your evaluation.
From raw material to a sealed export bag, in five controlled steps.
Raw material selection
Wood chips, coconut shell, nutshell, coal or bamboo are graded on moisture and ash before carbonisation.
Carbonisation
Material is carbonised at controlled temperature to build the initial pore skeleton.
Activation
Steam or chemical activation opens the pore network; the route used is recorded on the specification plan.
Drying and screening
Product is dried to the target moisture and screened to the ordered mesh range.
QC and packing
Each batch is tested in the in-house laboratory, retained for 12 months and packed to the order.

Common questions from buyers evaluating coal-based granular activated carbon.
What information do you need for a quotation?
The medium to be treated, the flow rate or concentration, the target specification and the required particle size. With those we confirm the grade and the agreed specification plan before pricing.
Can you supply a trial sample?
Yes. A 1-5 kg sample is supplied for evaluation, with freight at the buyer's cost. Larger evaluation quantities can be discussed with your technical engineer.
What is the minimum order quantity and the lead time?
MOQ is 1 tonne. Standard lead time is 15 days; stock items ship within 3-5 days. Production progress is updated weekly.
Which documents are issued with a shipment?
CO, Form E, MSDS and COA can be issued. Third-party inspection through SGS or BV is available when the order calls for it.
