DESCRIPTION
Explore description details to support your evaluation.
Granular coconut shell activated carbon is a porous carbon material produced from coconut shell char by high-temperature activation. It is widely used in industrial water filtration where consistent hydraulic behaviour and reliable adsorption performance matter, such as municipal and industrial water treatment, process water polishing, and the removal of colour, taste, odour and residual organic compounds.
Where it fits in an industrial water treatment line
Granular carbon is commonly applied in fixed-bed filter vessels, pressure filters and open gravity beds. Its granular form allows water to pass through a packed bed with relatively low pressure loss, and the bed can be backwashed to remove accumulated solids during service. Typical positions in the treatment train include pre-treatment ahead of demineralisation or membrane stages, post-treatment polishing after clarification, and dedicated carbon filters for removing organics from process water.
Choosing the right grade
Selection should be based on the water analysis, target contaminants, contact time and the design of the filter vessel. Two values in this series are particularly important for process design: the iodine number, which relates to the adsorption capacity for small molecules, and the hardness, which influences the mechanical durability of the granules during backwashing and handling. Buyers should also confirm the particle size distribution against the vessel design, since it affects both pressure drop and filtration behaviour. Final performance should always be validated under the actual operating conditions, because feed water quality and contact time are site specific.
For a quotation or technical discussion, please share your water analysis, flow rate, vessel dimensions and target outlet quality so that the most suitable grade can be recommended.

The points below summarise the practical reasons buyers select granular coconut shell activated carbon for water filtration duties.
Suitable for fixed-bed filtration
The granular form is designed for packed-bed service, allowing water to flow through the bed with manageable pressure loss and enabling backwashing when the bed accumulates suspended solids.

PACKAGING
Explore packaging details to support your evaluation.
Standard export packing options for granular activated carbon; final packing is agreed with the order.
PROCESS
Explore process details to support your evaluation.
Granular coconut shell activated carbon is produced through a controlled sequence of thermal and mechanical steps.
Raw material selection
Coconut shell is selected and cleaned to provide a consistent feedstock for carbonisation.
Carbonisation
The shell is heated in a low-oxygen atmosphere to convert it into carbon-rich char.
High-temperature activation
Steam or gas activation develops the internal pore structure that gives the carbon its adsorption capacity.
Screening and grading
The activated material is screened and graded so that the particle size distribution matches the intended filter bed.
Quality control and packing
Reference parameters such as iodine number, hardness, moisture and ash are checked on the batch sample before the material is packed.

Common questions buyers ask when specifying granular coconut shell activated carbon for water filtration.
What information is needed to select the right grade?
Please share the water analysis, target contaminants, flow rate, required contact time and filter vessel dimensions. These inputs determine the appropriate particle size, iodine number and bed depth for the duty. Final performance should be confirmed under actual operating conditions.
Are the listed specifications guaranteed for every batch?
The values shown are reference values from the series range. The actual batch value is confirmed before quotation, and parameters such as iodine number, hardness, moisture and ash are checked on the batch sample.
Can samples and documents be provided?
Samples can be discussed with your sales contact so the material can be evaluated against your water and vessel design. Available documents are confirmed with the order; no specific certification or test report is implied here.
