Activated carbon explained: Learn its types, uses, and benefits in water treatment, air purification, food industry, and more. Buy from Zhongci Environmental Ceramics Materials.
Activated carbon is one of the most widely used adsorbent materials in the world. Due to its extremely high surface area and porous structure, it is capable of capturing and holding a wide range of impurities from liquids and gases. Whether it is used for water purification, air cleaning, or industrial processes, activated carbon plays a critical role in improving environmental quality and human health.
At Zhongci Environmental Ceramics Materials (🌐 www.chempackings.com), we provide high-quality activated carbon solutions tailored to different industries. Below, we explain everything you need to know before choosing the right activated carbon for your application.
What is Activated Carbon?
Activated carbon is a specially processed form of carbon that has been treated to create millions of tiny pores. These pores drastically increase the surface area available for adsorption. In fact, just one gram of activated carbon can have a surface area of 500–1500 square meters.
The unique porous structure allows it to:
- Trap molecules from liquids and gases
- Remove toxins, colors, odors, and harmful chemicals
- Purify products and improve safety
Main Types of Activated Carbon
Activated carbon is classified by both raw material and physical form. Each type serves different needs:
1. By Raw Material
- Coconut Shell Activated Carbon
- High hardness and durability, low dust content
- Excellent microporous structure for adsorbing organic compounds, VOCs, and odors
- Popular in drinking water filters, aquariums, and air purifiers
- Coal-Based Activated Carbon
- Widely available and cost-effective
- Balanced pore structure for wastewater treatment and industrial gas cleaning
- Frequently used in power plants, refineries, and sewage treatment
- Wood-Based Activated Carbon
- Lightweight, with larger pore size distribution
- Very effective in decolorization and purification of liquids
- Commonly applied in the food industry (sugar, wine, edible oils) and pharmaceuticals
2. By Physical Form
- Powdered Activated Carbon (PAC)
- Fine powder form, quick adsorption, easy mixing with liquids
- Ideal for short-term treatment of water or beverages
- Granular Activated Carbon (GAC)
- Larger granules, suitable for long-term filtration in fixed beds
- Widely used in municipal water plants and household water filters
- Extruded or Pelletized Activated Carbon
- Cylindrical pellets, mechanically strong and low dust
- Perfect for air purification systems, solvent recovery, and gas phase adsorption

Functions and Applications
Activated carbon is extremely versatile. Its most common uses include:
- Water Treatment
- Removes chlorine, pesticides, heavy metals, and organic contaminants
- Essential for safe drinking water, aquarium systems, and wastewater treatment
- Air and Gas Purification
- Eliminates volatile organic compounds (VOCs), industrial emissions, smoke, and odors
- Used in home air purifiers, automotive filters, and gas masks
- Food and Beverage Industry
- Refines sugar, removes color from juices, wines, and oils
- Ensures better taste, quality, and appearance of products
- Medical and Pharmaceutical Applications
- Used in detoxification treatments, poisoning antidotes, and drug purification
- Plays a role in active pharmaceutical ingredient (API) purification
- Environmental Protection and Industry
- Controls air pollution and reduces wastewater pollutants
- Applied in chemical industries for solvent recovery and gas scrubbing
Important Notes When Using Activated Carbon
Adsorption Capacity is Limited
- Once saturated, activated carbon can no longer capture impurities and must be replaced or regenerated.
Moisture Sensitivity
- In air purification, high humidity reduces efficiency since water can block pores.
Quality Variation
- Different carbons have different pore sizes, iodine values, and hardness levels. The wrong choice may result in poor performance.
Proper Disposal or Regeneration
- Used activated carbon may contain hazardous substances and should be handled correctly.
How to Choose the Right Activated Carbon
- Define Your Application
- Drinking water → Coconut shell carbon
- Wastewater treatment → Coal-based carbon
- Food and pharmaceutical decolorization → Wood-based carbon
- Air purification → Pelletized carbon
- Check Key Parameters
- Iodine value – measures adsorption capacity
- Surface area – higher values mean more adsorption
- Hardness – important for industrial use to avoid carbon dust
- Select the Correct Form
- PAC for fast treatment
- GAC for long-term continuous use
- Pellets for gases and air filtration
- Consult an Expert
- Matching the right type to your specific conditions ensures the best results and cost-effectiveness.
