Industrial Carbon Product Portfolio
Every industry requires specific pore architectures and physical forms. We engineer activated carbon products formulated for maximum adsorption efficiency, superior mechanical durability, and zero-defect consistency.
1. Coconut Shell Based Activated Carbon
Manufactured from carefully selected mature coconut shells activated through controlled high-temperature steam activation. Coconut shell activated carbon has the highest microporosity among all raw materials, with more than 80% of its internal pore volume consisting of pores under 2 nanometers. This provides an extraordinary internal surface area (exceeding 1,100–1,200 m²/g) ideal for the selective capture of low-molecular-weight organic pollutants, free chlorine, ozone, trihalomethanes (THMs), and precious gold-cyanide complexes.
Core Product Features:
Key Industrial Applications:
- Potable Water Filtration: Rapid dechlorination, chloramine reduction, and taste/odor removal in municipal and industrial purification systems.
- Gold Extraction (CIL / CIP / CIC): Exceptional mechanical hardness prevents granule attrition and eliminates soluble gold losses in carbon-in-leach circuits.
- Air & Gas Purification: Removing volatile organic compounds (VOCs), solvent vapors, and toxic gases from industrial exhausts.
- Beverage & Food Processing: Deodorization, dechlorination, and polishing of brewery, soft drink, and mineral water feed streams.
- Medical & Hemoperfusion: Ultra-pure hemodialysis water polishing with zero chemical additive leachables.

2. Wood Based Activated Carbon
Manufactured from selected sustainable hardwood sawdust and lumber through chemical activation (phosphoric acid) or high-temperature steam thermal processing. Unlike coconut carbon, wood-based activated carbon is dominated by mesopores (2 to 50 nm) and macropores (>50 nm). This pore structure makes it exceptionally capable of adsorbing large-diameter organic molecules, humic acids, synthetic coloring agents, proteins, and caramel bodies.
