FAQs
The right activated carbon depends on the contaminants to be removed, the treatment process, operating conditions, and the required adsorption performance. Different applications may require different carbon types, particle sizes, iodine values, hardness, ash content, or other specifications.
For example, powdered activated carbon is commonly considered for liquid-phase treatment where rapid adsorption and easy dosing are important. Granular activated carbon is often selected for fixed-bed filtration systems, while pelletized carbon can be suitable for gas-phase treatment and applications where controlled airflow and lower pressure drop are important.
If you share your application, target contaminant, treatment process, and operating conditions, we can recommend a suitable activated carbon grade and specification.
Yes. Activated carbon can be supplied in different grades according to application requirements. Depending on the product type and production conditions, specifications such as iodine value, CTC activity, hardness, particle size, ash content, moisture, and bulk density can be discussed for a specific application.
For particle size, we can provide different mesh ranges or pellet diameters depending on the intended use.
If you already have a technical specification or target parameters, you can send them to us for evaluation. We can then confirm the available grade and provide the corresponding technical data.
Yes. Samples can be provided for customers who need to evaluate activated carbon before placing a larger order.
Sample testing can help you assess important characteristics such as adsorption performance, particle size, moisture, hardness, or compatibility with your existing treatment process.
For application-specific projects, we recommend testing the sample under conditions as close as possible to your actual operating environment. This provides a more meaningful basis for selecting the appropriate grade than comparing specifications alone.
Please contact us with your application details and required specification so we can discuss the appropriate sample.
Activated carbon can be packed according to the product type, order quantity, transportation method, and customer's requirements.
Common export packaging options include 20kg、25kg and 500kg bags. Smaller quantities can also be arranged in smaller inner packages when required for sampling or specific applications.
For international shipments, packaging should provide adequate protection against moisture, contamination, and physical damage during handling and transportation.
If you have specific packaging, labeling, or shipping requirements, please provide them when requesting a quotation so we can recommend a suitable packing solution.
Coconut shell activated carbon is widely associated with high microporosity and is often considered for applications requiring adsorption of smaller molecules, including certain water treatment and gold recovery applications.
Coal-based activated carbon offers a broader pore structure and can be produced in different forms and grades. It is commonly used across water treatment, industrial purification, and other adsorption processes.
Wood-based activated carbon is often characterized by a relatively developed mesoporous structure and is frequently considered for applications such as color removal, decolorization, and adsorption of larger organic molecules.
When comparing activated carbons, it is better to evaluate the complete specification—including pore structure, iodine value, CTC, hardness, ash, particle size, and application-specific adsorption performance—rather than selecting a raw material based on its name alone.
