Applications
Pellet activated carbon is versatile across industries, leveraging its robust structure for fixed-bed and dynamic systems:
- Gas and Air Purification: Removal of VOCs, H2S, siloxanes, and odors from industrial emissions, biogas, and ventilation systems.
- Water and Wastewater Treatment: Dechlorination, organic contaminant removal, and color/odor reduction in municipal, industrial, and process water.
- Solvent Recovery: Adsorption and regeneration in chemical processing, paints, and printing operations.
- Food and Beverage: Decolorization and purification in juice, wine, and sugar processing.
- Utilisations spécialisées: Catalyst support, mercury vapor control, and flue gas treatment in environmental engineering.
Quality Standards and Compliance
- Testing Standards: Conforms to ASTM (e.g., D2862 for particle size, D4607 for iodine number) and ISO (e.g., 21340 for properties).
- Certifications: Food-grade compatible (ANSI/NSF 61 for drinking water), AWWA B604 for granular activated carbon.
- Regulatory Compliance: REACH registered, non-hazardous per OSHA and EU CLP; no PBT/vPvB substances.
Emballage et stockage
- Standard Packaging: 25 kg bags, 500-1000 kg big bags, or bulk shipments on pallets (strapped and shrink-wrapped).
- Storage Recommendations: Store in a cool, dry, well-ventilated area away from strong oxidizers and direct sunlight. Avoid contact with air or organic vapors to prevent premature saturation. Shelf life: Up to 2 years under proper conditions.
Safety and Handling
- Hazards: Non-hazardous dust; may cause eye/skin irritation or oxygen depletion in confined spaces when wet. Ignition temperature >400°C.
- PPE: Wear gloves, eye protection, and respiratory mask in dusty areas. Avoid inhalation and contact.
- First Aid: Rinse eyes/skin with water; seek medical attention if irritation persists.
- Disposal: Non-hazardous; dispose per local regulations. Spent carbon may require hazardous waste classification based on adsorbed contaminants.
