Coal Based Activated Carbon
Overview
Coal-based activated carbon is a versatile adsorbent derived from bituminous or other coal sources through high-temperature activation processes. It features a porous structure ideal for capturing impurities in liquids and gases, commonly used in water purification, air treatment, and industrial processes. This product complies with international standards such as AWWA B604 for granular applications and NSF/ANSI 61 for drinking water contact, ensuring safety and efficacy for global B2B buyers.
Features
- High surface area (typically 900-1,000 m²/g) for efficient adsorption.
- Balanced micropore, mesopore, and macropore distribution for broad contaminant removal.
- Durable with high abrasion resistance (75-80% minimum), reducing dust and extending service life.
- Available in granular forms like 8×30 mesh for easy integration into filtration systems.
Applications
- Water treatment: Removes taste, odor, chlorine, and organic compounds in potable and wastewater systems.
- Air purification: Controls odors and volatile organic compounds (VOCs) in industrial vents and remediation.
- Industrial uses: Decolorization, heavy metal removal, and gas phase adsorption in chemical processing.
Advantages
- Cost-effective with longer bed life compared to some alternatives, minimizing replacement frequency.
- Reactivatable, supporting sustainable operations and reducing waste.
- Meets global regulatory needs, facilitating international trade under standards like INCOTERMS.
