High-Quality Activated Carbon Suppliers in China - Factory Direct for Water Purification & Air Filtration
Product Description
Our activated carbon is a highly porous form of carbon engineered through a controlled activation process (physical or chemical) to create an extensive network of microscopic pores. This results in an exceptionally large surface area (typically 500-1500 m²/g), granting it outstanding adsorption properties. It effectively attracts and holds a wide range of impurities, chemicals, odors, and contaminants through physical adsorption and catalytic reduction. We offer various raw material bases—including coconut shell, coal, and wood—each optimized for specific performance characteristics in filtration and purification applications.

How to use
System Design: Select the appropriate form (GAC/PAC), base material, and particle size based on the target contaminant and contact system (e.g., fixed bed, fluidized bed).
Loading: For fixed-bed filters, load GAC to the recommended bed depth. Ensure uniform distribution to prevent channeling.
Pre-treatment (if required): Rinse GAC with clean water to remove fines before initial use in liquid applications.
Operation: Pass the fluid (air or water) through the carbon bed at the designed flow rate. Monitor pressure drop and effluent quality.
Replacement/Regeneration: Replace carbon upon exhaustion (breakthrough). Spent GAC can often be thermally reactivated for reuse.

Storage Method
Store in a cool, dry, and well-ventilated warehouse on pallets. Keep bags sealed tightly to prevent adsorption of moisture and odors from the atmosphere, which can prematurely saturate the carbon. Store away from strong oxidizing agents, volatile chemicals, and direct sunlight. Use a first-in, first-out (FIFO) inventory system.
FAQ
Q1: What is the difference between Coconut Shell, Coal, and Wood-based Activated Carbon?
A: The primary difference lies in their pore structure and best applications. Coconut shell carbon has a high microporosity, ideal for gas/vapor adsorption and gold recovery. Coal-based carbon has a broader mix of micropores and mesopores, making it excellent for general liquid-phase purification (water treatment). Wood-based carbon often has more macropores, suitable for decolorization of liquids.
Q2: How do I choose between Granular (GAC) and Powdered (PAC) Activated Carbon?
A: GAC is used in fixed-bed filters (like home water filters) for continuous flow processes. PAC is typically dosed into a process stream (like wastewater) as a slurry, then separated after contact. GAC is for dedicated filtration systems; PAC is often for batch treatment or specific contaminant spikes.
Q3: What does the Iodine Number indicate?
A: The Iodine Number is a standard test that measures the microporosity (pores < 2 nm) of the carbon. A higher iodine number (e.g., >1000) generally indicates a greater capacity to adsorb small molecules, like those found in gases and some chemicals.
Q4: How long does activated carbon last? When should it be replaced?
A: Service life depends entirely on the contaminant load and flow rate. It lasts until it becomes "saturated" and breakthrough occurs. In home water filters, this can be 3-6 months. In industrial settings, it's monitored by effluent testing. It should be replaced when the desired purity level can no longer be maintained.
Q5: Can spent activated carbon be regenerated?
A: Yes, thermally. Spent carbon can often be sent to specialized facilities for high-temperature thermal reactivation, which restores its adsorption capacity, making it a more sustainable option compared to disposal. However, this is typically economical only for large volumes of spent GAC.
