DESCRIPTION
Explore description details to support your evaluation.
This wood-based granular activated carbon is produced for liquid-phase and gas-phase adsorption duties, including municipal and industrial water treatment, process water polishing, and air and gas purification where a granular medium is required. The granular form suits fixed-bed and column arrangements, where pressure drop and handling behaviour matter alongside adsorption capacity.
Typical applications include drinking water and wastewater treatment, groundwater remediation, decolourisation and purification in food and beverage processing, and solvent or odour control in air handling systems. Because wood-based carbon combines a well-developed pore structure with relatively low ash, it is often evaluated where both adsorption performance and ash-related constraints are part of the selection criteria.
For procurement teams in Europe and North America, the meaningful comparison is not a single headline number but the whole specification: iodine value, methylene blue adsorption, hardness, ash content, particle size and moisture. The values published here are reference figures for the series; the batch certificate confirms the actual values shipped against the agreed specification. Buyers are encouraged to test a trial sample against their own medium before committing to volume.
To receive a quotation, please share the medium to be treated, the flow rate or concentration, the target particle size, and any document or certification requirements for your market. We will confirm the suitable grade and specification plan before pricing.

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.

PROCESS
Explore process details to support your evaluation.
From wood raw material to a sealed export bag, in controlled steps.
Raw material selection
Wood raw material is graded on moisture and ash before carbonisation, so the starting material is consistent with the intended grade.
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 for the batch.
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 European and North American buyers evaluating wood-based granular activated carbon.
What information do you need to quote a wood-based granular grade?
The medium to be treated, the flow rate or concentration, the required particle size, and any target specification or document requirements. With those details we confirm the grade and the agreed specification plan before pricing.
Can you supply a trial sample for evaluation?
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.
How are the specification figures confirmed?
The values shown on this page are reference figures for the series. The batch certificate states the actual values and the method used, and the batch value is confirmed before quotation.
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.
