DESCRIPTION
Explore description details to support your evaluation.
Coal-based activated carbon from Sanniu Carbon is a durable, granular adsorbent produced by carbonizing and steam-activating selected coal. The process creates a broad internal pore network that captures dissolved organics, chlorine, taste-and-odor compounds and many volatile organic compounds from water and air streams. Its hardness and granular form suit packed beds, pressure vessels and continuous flow systems where a stable support and low fines matter.
These grades are typically used for municipal and industrial water treatment, process water polishing, air purification and solvent recovery. As water or gas passes through the bed, contaminants are held on the pore surfaces, so performance depends on contact time, flow rate, inlet concentration and the amount of carbon in the column. Iodine value reflects overall micropore activity, while methylene blue adsorption indicates mesopore and larger-molecule capacity. Balance these indicators against pressure drop, bed life and regeneration or replacement plans.
When selecting a grade, confirm the application and target contaminant first, then match the mesh cut and adsorption profile to the vessel and flow conditions. Batch certificates normally report iodine value, moisture, BET surface area, hardness, ash and bulk density, with actual figures confirmed before quotation or order release. Because granular carbon can settle and compact in service, plan backwashing and loading with the supplier. For drinking-water or food-contact duties, confirm the relevant regulatory documentation at the enquiry stage.
To receive a suitable recommendation, send your application, treated medium, flow rate or vessel size, target contaminants and outlet requirement, preferred mesh size and estimated quantity. Sanniu Carbon can then propose a coal-based grade and confirm the batch specification and available documents for your evaluation.

Our inquiry-to-order process helps buyers confirm the right coal-based activated carbon grade before quotation.
Share your application and treatment goal
Tell us what you need to treat, such as water, air or another medium, and the target result. This frames the selection discussion.
Confirm product form and working conditions
We review granular or powder form, flow or concentration data, and the operating context so the grade direction fits your process.
Review the applicable specification range
We explain the series reference values and the scope of the documents cited. Batch indicators and available files are confirmed before the transaction.
Agree on mesh cut and packaging
Screened particle size, mesh cut and moisture protection requirements are checked at order confirmation, based on the order information both sides accept.
Confirm commercial terms in writing
Price, available quantity and lead time are verified by our team and stated in the written quotation or order confirmed by both parties.

Common questions from buyers comparing coal-based activated carbon series, specifications and documents.
What should buyers check when comparing coal-based activated carbon?
Start with the medium to be treated and the operating conditions, then compare the series level figures for iodine value, methylene blue adsorption, BET surface area and CTC adsorption. For coal-based granular grades, check hardness, ash, moisture, bulk density and the agreed mesh cut as well. All figures are reference values from the series range or batch-sample measurements; the batch value is confirmed before quotation.
Which coal-based series fits water or air purification?
Selection depends on the target compound, the concentration, the contact time and whether the bed is used for liquid or gas phase duty. Coal-based granular carbon suits many fixed-bed water and air applications because its pore structure and mechanical strength support repeated backwashing and regeneration. Share the duty and the target specification, and we will confirm the suitable grade and the agreed specification plan.
Can the particle size and mesh cut be agreed before ordering?
Yes. The particle size range is screened, and the required mesh cut is agreed before the order. Provide the preferred mesh cut, the permissible fines level and the handling or filter arrangement so the grade can be matched to the equipment. The final cut and the batch figures are stated in the confirmed order information.
Which documents and reports can support an inquiry?
The company holds an ISO 9001:2015 quality management certificate covering activated carbon sales, valid 12 June 2024 to 11 June 2027. RoHS sample reports and a safety data sheet can also be provided. These documents refer to the named samples or scope only; batch-specific certificates of analysis are confirmed before delivery. Tell us which documents your compliance process needs.
How are samples, price, quantity and delivery confirmed?
After receiving an inquiry we review the application, treatment target and product form, then discuss the selection direction and confirm the applicable specifications and documents. Price, available quantity and delivery are checked manually and confirmed in a written quotation or order. Packaging and moisture-control requirements are agreed at order confirmation, and we follow up on use or documentation questions through the agreed contact channel.
Which details should be included in the inquiry?
Include the medium or gas to be treated, the flow rate or concentration, the target specification, the required particle size, the estimated purchase quantity and any document or packaging requirements. That lets us confirm the suitable coal-based grade and the specification plan without substituting assumptions for the application data. Inquiries are answered by our team rather than by an automated quotation.
