Activated Carbon Knowledge Base
Technical guides and procurement notes on activated carbon selection, quality metrics and application processes.
8 Parameters to Specify When Writing an Activated Carbon Specification
In tenders and procurement most specs list only the iodine number. An incomplete spec means the wrong product, capacity problems and disputes. The 8 core parameters your spec must request.
Iodine Number vs. Real Performance: Why It Is Not Enough on Its Own
The iodine number is the most common quality metric but it does not guarantee field performance on its own. What it measures, what it misses, and which additional parameters to check.
GAC Bed Life and Empty Bed Contact Time (EBCT) in Wastewater Treatment
Empty bed contact time (EBCT) is the most critical design parameter for granular activated carbon columns. How to calculate it, what determines bed life, and how to estimate breakthrough.
How to Calculate PAC Dosage for Color Removal in Sugar Syrup
With powdered activated carbon (PAC) in sugar syrup decolorization, dosage is not a fixed number. What it depends on, how to determine it with a jar test, and what improves efficiency.
Choosing Impregnated Carbon for H₂S and NH₃ Removal: KOH or Iodine?
The choice of impregnated activated carbon for odor control depends on the gas. When to use caustic (KOH), iodine/catalytic and acidic impregnation.
CIL/CIP Carbon Selection in Gold Mining: Hardness, Gold Loading and Attrition Loss
Carbon selection in CIL/CIP processes rests on three critical metrics: hardness (attrition resistance), gold loading capacity and attrition loss. How to balance these three.
Activated Carbon Regeneration: How It Lowers Operating Cost
Thermal regeneration of spent activated carbon significantly reduces operating cost under the right conditions. When does regeneration make sense, and when is new product the better choice?
What Is the Activated Carbon Iodine Number? How Does It Affect Quality?
The iodine number is the most common quality metric showing the adsorption capacity of activated carbon. How it is measured, which values are considered good, and its relationship to surface area.
Differences Between Granular Activated Carbon (GAC) and Powdered Activated Carbon (PAC)
The structural and application differences between granular and powdered activated carbon, which to choose in which situation, and a cost-performance comparison.
