— ACTIVATED CARBON
Charbon actif granulaire (GAC)
Coconut shell, coal-based and wood-based GAC options selected around flow, contact time, adsorption duty and mechanical requirements.
— PRODUCT OVERVIEW
Granular Activated Carbon for Fixed-Bed Systems
Granular activated carbon is used in fixed beds, pressure vessels and replaceable media systems. The correct GAC grade balances adsorption performance with particle size, pressure drop, backwash behavior, attrition resistance and bed life.
Raw material and mesh size influence performance, but they should be selected together with the target contaminant, empty-bed contact time, hydraulic conditions and relevant test method.

Available Granular Activated Carbon Options
Select a product form or treatment route below. Final grade selection should be based on the application, target contaminant, process conditions and required specification.
Coconut Shell GAC
A hard granular option commonly evaluated where fine-pore adsorption and mechanical durability are important.
Typical fit: water purification, selected gas duties and precious-metal recovery after grade review.
Coal-Based GAC
A broad-duty granular option available for liquid- and gas-phase systems with application-specific pore and size requirements.
Typical fit: industrial water, wastewater, process purification and selected vapor treatment.
Wood-Based GAC
A granular option considered where wood-derived pore characteristics are relevant and the product meets bed-stability needs.
Typical fit: selected liquid purification and decolorization systems.
— SELECTION GUIDE
How to Select the Right Grade
Begin with the vessel and process conditions. Then compare raw material, size distribution, adsorption index, hardness, ash and operational requirements.
1. Application & target
Define flow rate, bed dimensions, contact time, backwash conditions and target contaminant.
2. Product form
Compare coconut shell, coal-based and wood-based pore structures against the adsorption duty.
3. Performance requirement
Balance particle size with kinetics, pressure drop and media-retention requirements.
4. Required specification
Confirm adsorption tests, hardness, ash, moisture, density and documentation.

| Adsorption index | Must relate to the target contaminant | Confirmed for the selected grade and test method |
| Hardness / abrasion | Affects fines generation and handling | Confirmed for the selected grade and test method |
| Bulk density | Supports vessel loading and logistics | Confirmed for the selected grade and test method |
| Moisture | Defines delivered condition | Confirmed for the selected grade and test method |
| Ash / pH | Reviewed for process compatibility | Confirmed for the selected grade and test method |
— APPLICATIONS
Where This Product Is Considered
GAC is applied in fixed-bed systems across water, air, industrial and recovery processes. Each duty requires a different grade-selection basis.
Traitement de l'eau
GAC beds can be evaluated for municipal, process or wastewater treatment.
Purification de l'air
Granular grades may be used where the gas system and pressure drop are suitable.
Récupération des métaux précieux
Selected hard GAC grades may be evaluated for recovery circuits.

Ordering & Documentation
Packaging format, minimum order quantity, sample availability, lead time, labeling and private-label requirements are confirmed for the selected grade, quantity and destination market. Nothing is assumed before the commercial review.
For regulated or specification-sensitive uses, ask which COA, TDS, SDS, test reports or other documents are available for the exact product under discussion.

— FAQ
Frequently Asked Questions
What does GAC mean?
GAC means granular activated carbon: particles sized for beds or media systems rather than direct powder dosing.
How do I choose a GAC mesh size?
Use hydraulic loading, pressure drop, contact time, retention screens and backwash conditions. The smallest particle is not automatically best.
Which raw material should I choose?
Compare the target contaminant and pore requirement with the mechanical, purity and commercial needs of the process.
Why does hardness matter?
Hardness and abrasion behavior help indicate resistance to handling and fines generation in a granular system.
Can GAC be used in air and water?
Yes, but liquid- and gas-phase duties often require different sizes, adsorption tests and product properties.
What should be included in an inquiry?
Send the application, contaminant, flow, vessel or bed details, preferred size, required tests, quantity and destination.
