Coal is widely available, but its quality and price can be subject to mining and energy market fluctuations. The coal segment is expected to dominate the market, indicating its central role in the global supply. This type is known for its wide range of pore sizes, making it versatile for general purification tasks.
- Coconut Shell-Based: Produced from coconut shells, this type is valued for its high hardness and microporous structure, ideal for removing smaller organic contaminants in water and air purification applications. The supply is concentrated in tropical regions, making it susceptible to agricultural yields and regional logistics.
- Wood-Based: This type has a macroporous structure, making it suitable for decolorizing liquids and removing larger molecules. Its supply is tied to the forestry and timber industries.
Identifying Your Specific Application Requirements
Matching the carbon to the application is critical. Consider the following factors:
- Phase: Are you treating a liquid (e.g., water, wastewater) or a gas (e.g., air, industrial off-gas)?
- Contaminants: What specific substances are you targeting for removal? Are they organic compounds, chlorine, heavy metals like mercury, or color bodies? The chemistry and molecular size of the contaminants will dictate the ideal pore structure.
- Process Conditions: What are the operating flow rates, temperature, pH, and pressure of your system? These parameters affect adsorption kinetics and the physical integrity required of the carbon media.
- Regulatory Standards: What are the required effluent or emission standards you must meet? This defines the necessary performance and purity of the activated carbon.
The Importance of Activated Carbon Specifications
Once you understand your application, you can define the technical specifications for the product. These are not just numbers on a data sheet; they are direct indicators of performance and quality that form the basis of your Request for Proposal (RFP). Key specifications include:
- Form: Do you need Granular Activated Carbon (GAC) for use in large filter beds, or Powdered Activated Carbon (PAC) for dosing directly into treatment streams? GAC is used in continuous processes like municipal water treatment, while PAC is often used in batch processes for wastewater.
- Particle Size (Mesh Size): This affects the pressure drop across a filter bed and the rate of adsorption.
- Activity Level (Iodine/Molasses Number): The Iodine Number indicates the micropore content and is a measure of the carbon’s ability to adsorb small molecules. The Molasses Number indicates macropore content and the capacity for larger color molecules.
- Номер твердости/абразивности: This measures the carbon’s physical durability, which is crucial for applications involving backwashing or reactivation to minimize product loss.
- Содержание золы: Represents the non-carbon, inorganic content, which can impact performance and pH.
