DESCRIPTION
Explore description details to support your evaluation.
Sanniu Activated Carbon supplies coal-based, coconut shell, wood-based, nutshell and bamboo activated carbon in granular, powder and block form. Iodine value, particle size, hardness and ash content are stated per batch, so procurement and technical teams can compare grades on the same basis.
We run physical and chemical activation lines and test every batch in our own QC laboratory, with SPC control across the process and samples retained for 12 months. Third-party inspection through SGS or BV can be arranged when the order requires it.
Tell us the medium to be treated, the flow rate or concentration and the target particle size, and we will confirm the suitable grade and the agreed specification plan before quotation.

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.
