What are the Key Properties of Activated Carbon

The 9 key properties of activated carbon are listed below :
?

High Surface Area

The most critical property. Activated carbon has an immense internal surface area (often over 1,000 m²/g) due to its network of pores, which is where adsorption takes place.
?

Pore Structure

The size and distribution of pores (micropores, mesopores, and macropores) are crucial for selective adsorption. Micropores are ideal for small molecules, while larger pores can accommodate bigger organic molecules.
?

Iodine Value

A standard measurement of the total micropore volume and surface area, which indicates the carbon’s adsorption capacity for small molecules.
?

Hardness/Abrasion Resistance

This measures the carbon’s mechanical strength and its ability to withstand friction and physical degradation during handling and use in filters.
?

Density

Both bulk density and apparent density are important for designing filtration systems.
?

Ash Content

The non-carbon inorganic residue remaining after combustion. Lower ash content is generally preferred for purity-sensitive applications like food and pharmaceuticals.
?

pH

The pH of the carbon can be an important factor for certain applications, such as in water treatment or gold recovery.
?

Particle Size Distribution (PSD)

The size of the carbon granules or powder affects the rate of adsorption and the pressure drop across a filter bed.
?

Adsorbent Activity

A measure of the carbon’s overall ability to adsorb a specific contaminant, often tested with a specific chemical like Methylene Blue or CTC (Carbon Tetrachloride).

Activated Carbon FAQs & Concerns

What is Activated Carbon?
Activated carbon’s high porosity and massive internal surface area allow it to attract and trap impurities through a process called adsorption, making it highly effective for purification.
How Adsorption Works with activated carbon?
Adsorption is a surface phenomenon where molecules of a substance (adsorbate) are attracted and held onto the surface of a solid (adsorbent). Activated carbon’s vast surface area acts like a magnet, trapping impurities from liquids or gases as they pass through.
What types of activated carbon are offered?
Activated carbon base materials Typically Activated Carbon is either coconut shell based or wood based or coal based, the base material from the above 3, undergoes a heat-treatment process to create an immense internal surface area for trapping contaminants through adsorption. We also offer Acid Washed and Acid Activated carbon for specific applications
Coconut shell, wood, or coal-based – which is right for my application?
  • Coconut shell-based: Best for small molecules, high-purity water, gold recovery, solvent recovery, and air purification requiring high hardness and long life.
  • Wood-based: Suited for larger molecules, decolorization in sugar, edible oils, and chemical solutions.
  • Coal-based: For large-scale municipal/industrial water treatment, remediation projects, and air/gas purification.
What are common causes of failure or reduced performance of activated alumina?

Common issues include:

  • Exposure to liquid water (rather than vapour) or saturated streams — causes rapid adsorption, heat release and cracking (“rehydration damage”)
  • Heavy oils, tars or polymerizable compounds fouling the pore surfaces
  • Use in highly acidic (pH < 5) or highly alkaline (pH > 12) environments causing alumina dissolution
  • Lack of proper particulate/oil filtration upstream, causing bed plugging or high pressure drop
    These reduce performance, shorten service life, and may lead to breakdown.
What storage and handling practices should be followed for activated alumina?
Follow the practices to:

  • Store in a dry, sealed condition; avoid exposure to moisture or ambient humidity before use
  • Protect from impact/dust generation — high attrition beads lose efficiency
  • Ensure vessels are designed for good flow distribution (to avoid channelling) and loaded over inert support layers (e.g., ceramic balls)
  • Prior to use, check that upstream filtration and system design supports the media life.
GAC, PAC, EAC, or Catalytic – which form should I choose?
  • Granular Activated Carbon (GAC): Continuous filtration in fixed beds (e.g., water plants, groundwater remediation, gold recovery).
  • Powdered Activated Carbon (PAC): Fast, one-time/batch treatments (e.g., taste/odor removal in municipal water, food decolorization).
  • Extruded Activated Carbon (EAC): Air/gas applications needing low pressure drop and high mechanical strength (e.g., VOC removal, odor control).
Do I need to prepare activated carbon before use?

Most grades arrive pre-treated and ready to use. For sensitive applications (e.g., food, pharma), a quick water rinse is recommended to remove fines. Always follow the handling guidelines provided with your order.

Can I regenerate and reuse activated carbon?
Yes — many industrial applications allow thermal or chemical regeneration. Regeneration efficiency depends on the contaminant type: water treatment carbons often regenerate well, while some industrial chemical loads may make it less economical.
How do I store activated carbon to maintain quality?
Keep in sealed, moisture-proof containers away from humidity and strong odors. Even unused carbon will adsorb moisture and airborne chemicals, reducing capacity before it’s in service.
How long will it last in operation?
Life expectancy varies:

  • Water treatment: Months to years, depending on contaminant load.
  • Air/gas purification: Longer lifespan if inlet air is dry and pre-filtered.
  • Gold recovery: Determined by ore characteristics and CIP/CIL circuit design.
    High-hardness coconut shell grades typically last the longest.
Which carbon should I use for air and gas purification?
  • EAC or CAC grades are best.
  • For VOC removal: Standard EAC.
  • For H₂S or corrosive gases: Impregnated EAC
  • For HVAC and odor control: EAC with low dust and uniform pellets.
Which carbon is ideal for (waste)water treatment?
  • Coconut shell GAC for high-purity water and low-organic loads.
  • Coal-based GAC for broad-spectrum municipal and industrial water treatment.
  • PAC for taste/odor control, algae toxin removal, or emergency contamination events.
What about gold recovery applications?
Use high-hardness coconut shell GAC for CIP and CIL circuits. Its microporous structure gives high gold adsorption capacity and resists attrition losses during circuit operation. Use high-hardness coconut shell GAC for CIP and CIL circuits. Its microporous structure gives high gold adsorption capacity and resists attrition losses during circuit operation.

Best Practices for Using Activated Carbon

Select the Right Base Material

  • Coconut Shell-Based: Choose for small-molecule adsorption, high-purity water, gold recovery, solvent recovery, and high-durability needs.
  • Wood-Based: Choose for large-molecule or color removal in food, beverage, and chemical industries.
  • Coal-Based: Choose for versatile, cost-effective, large-scale treatment of diverse contaminants in water, air, and soil.

Match the Form to the Application

  • GAC (Granular Activated Carbon): Best for continuous fixed-bed filtration with high abrasion resistance.
  • PAC (Powdered Activated Carbon): Best for quick, one-time dosing in liquids.
  • EAC (Extruded Activated Carbon): Best for air/gas purification with low pressure drop.

Pre-Use Preparation

  • Most carbons are supplied ready for use.
  • For sensitive applications (food, pharma, high-purity systems), rinse with clean water to remove fines before installation.

Optimize Contact Time & Flow Rate

  • Ensure empty bed contact time (EBCT) is present in fixed-bed systems to maximize adsorption.
  • Avoid excessive flow rates that cause channeling or reduced contact time.

Prevent Fouling & Blockage

  • Use pre-filtration to remove suspended solids and oils before using the carbon bed.
  • Avoid exposing carbon to oxidizing agents unless the grade is designed for it.

Monitor Performance Regularly

  • Track breakthrough points via air/water quality testing.
  • Replace/regenerate carbon bed when performance declines to prevent accidental contaminant release.

Regeneration & Replacement

  • Consider thermal or chemical regeneration where feasible for cost savings.
  • Some applications (especially decolorization) may require complete replacement due to irreversible fouling.

Storage & Handling

  • Store in sealed, moisture-proof containers away from humidity and strong odors.
  • Avoid prolonged exposure to air — activated carbon will adsorb moisture and airborne contaminants even when idle.

Safety Considerations

  • Activated carbon dust is combustible — avoid any ignition sources while handling.
  • Use appropriate PPE to prevent inhalation of fines.
