For B2B procurement managers and R&D scientists tasked with optimizing industrial water treatment processes, understanding the specifications of activated carbon is crucial. The selection of the correct type and grade of activated carbon directly impacts purification efficiency, operational costs, and overall system performance. As a leading manufacturer and supplier of coal granular activated carbon in China, we offer clarity on these vital parameters.

One of the most critical specifications for activated carbon is its Iodine Adsorption Value. Typically measured in mg/g, this value indicates the capacity of the activated carbon to adsorb small organic molecules, which are often representative of dissolved organic matter and other contaminants in water. For our coal-based granular activated carbon, values ranging from 600-1100 mg/g signify a high capacity for removing a broad spectrum of impurities, making it an excellent choice for general water purification.

Closely related is the Specific Surface Area, often measured in m²/g. A larger specific surface area, such as the 950 m²/g offered by our products, means more sites are available for adsorption to occur. This is directly linked to the pore structure of the activated carbon – a more developed pore network leads to a higher surface area and thus, greater adsorptive power. When you buy activated carbon, prioritizing a high specific surface area is a key indicator of its potential effectiveness.

The physical form and size of activated carbon are also critical. Granular activated carbon is preferred for many industrial applications due to its ease of handling, low pressure drop in filter beds, and suitability for regeneration. The mesh size, such as 4-8 mesh, 6-12 mesh, or 10-24 mesh, dictates the particle size distribution. These sizes affect flow rates and contact times within the treatment system. Specifying the correct mesh size, often through customization from a reliable supplier, ensures optimal performance for your specific filtration setup.

Mechanical Strength, often indicated as a percentage (e.g., 96%), is vital for ensuring the activated carbon can withstand the physical stresses of backwashing and handling without excessive attrition, which would lead to loss of media and reduced filtration efficiency. Additionally, parameters like Moisture Content (e.g., 4-6%) and Ash Content (e.g., 6-10%) are important indicators of product quality and purity.

As a dedicated manufacturer, we ensure our coal granular activated carbon meets these stringent specifications. We invite R&D scientists and procurement professionals to request samples and obtain quotes to experience the superior quality and performance. Understanding these specifications will help you make an informed decision when purchasing activated carbon for your industrial water treatment needs from a trusted China-based supplier.
