How to Choose the Right Activated Carbon
Activated carbon is widely used in water treatment, air purification, and industrial processes. However, choosing the right activated carbon is essential to achieve the best performance and cost efficiency. This guide will help you understand how to select between Powdered Activated Carbon (PAC) and Granular Activated Carbon (GAC) based on your application.
1. Understand the Main Types of Activated Carbon
Before selecting activated carbon, it is important to understand the two most common types used in industrial applications.
Powdered Activated Carbon (PAC)
Powdered Activated Carbon has a very fine particle size, usually between 200–325 mesh. It is commonly used in:
- Drinking water treatment
- Wastewater treatment
- Emergency pollution control
Granular Activated Carbon (GAC)
Granular Activated Carbon is larger in particle size and is typically used in fixed-bed filtration systems.
- Industrial water purification
- Air and gas treatment
- Recycling filtration systems
2. Key Factors to Consider When Choosing Activated Carbon
2.1 Application Type
Different industries require different adsorption performance. For fast adsorption, PAC is more suitable. For long-term filtration systems, GAC is preferred.
2.2 Raw Material Quality
High-quality coal-based activated carbon (especially anthracite-based) provides higher hardness, lower ash content, and better adsorption capacity.
2.3 Iodine Value and Adsorption Capacity
The iodine value reflects adsorption strength. Higher iodine value means better performance for removing organic contaminants.
2.4 Particle Size
Smaller particle size increases adsorption speed but may reduce filtration life. Larger particles improve flow resistance and durability.
3. Application-Based Selection Guide
| Application | Recommended Type | Reason |
|---|---|---|
| Drinking Water Treatment | PAC | Fast adsorption of organic pollutants |
| Industrial Wastewater | PAC / GAC | Depends on system design |
| Air Purification | GAC | Long-term filtration stability |
| Emergency Pollution Control | PAC | Quick reaction and dosing |
4. Why Coal-Based Activated Carbon Is Widely Used
Coal-based activated carbon, especially from high-quality anthracite, offers excellent hardness, high adsorption capacity, and stable performance. It is widely used in both PAC and GAC production.

6. Frequently Asked Questions (FAQ)
Q1: What is the main difference between PAC and GAC?
PAC is a fine powder used for fast adsorption, while GAC is used in filtration systems for long-term treatment.
Q2: Which activated carbon is better for wastewater treatment?
Both can be used depending on system design, but PAC is more commonly used for rapid treatment processes.
Q3: Can activated carbon be customized?
Yes, particle size, iodine value, and packaging can all be customized based on customer requirements.
