1. How do I choose the right type of activated carbon for my application?
The selection depends on your specific needs:
- Honeycomb activated carbon: Ideal for industrial VOCs abatement (e.g., paint booths, chemical plants) due to high adsorption speed and easy regeneration (matches our new product in Q4 2025).
- Powdered activated carbon (PAC): Best for water purification (drinking water, wastewater) and food/pharmaceutical 脱色 (compliant with EU Regulation (EC) No 1935/2004, as used in our German EcoWater order).
- Granular activated carbon (GAC): Suitable for low-flow applications like air filtration or small-scale water treatment.
Our team will also consider factors like adsorption capacity (e.g., iodine value), flow rate, and regeneration frequency to recommend the optimal solution.
2. What do key specifications like “iodine value” or “specific surface area” mean?
- Iodine value (mg/g): Measures the carbon’s ability to adsorb small molecules. Values 800–1200 mg/g work for organic compounds (e.g., VOCs, pesticides); higher values (1200+) suit heavy metal removal.
- Specific surface area (m²/g): Indicates total porous space. Our honeycomb carbon has a surface area of over 1800 m²/g, enabling faster VOCs capture than industry averages.
- Ash content: Critical for food/pharmaceutical use—our products have ash content <0.5% to meet FDA/CE standards.
3. Can your activated carbon meet international standards for my industry?
Yes. We hold certifications for global markets:
- Water treatment: CE (EU), NSF/ANSI 61 (US) for drinking water applications (used in Bavaria’s groundwater projects with EcoWater).
- Food/pharmaceutical: FDA compliance and EU Regulation (EC) No 1935/2004.
- Industrial use: ISO 9001 for quality management, and our Datong base has ISO 14064 carbon footprint certification for green production.
4. What is the typical delivery time for orders, and what is the minimum order quantity (MOQ)?
- Delivery time: 7–15 business days for standard products (e.g., powdered carbon for water treatment). Custom orders (e.g., specialized honeycomb carbon) take 2–4 weeks.
- MOQ: 10 tons for granular/powdered carbon; 50 cubic meters for honeycomb carbon. For large projects (e.g., municipal water plants), we offer flexible MOQs—contact our sales team for details.
5. Do you offer activated carbon regeneration services for used products?
Yes. Our Wuxi recycling center processes waste activated carbon using a “high-temperature activation + 1100℃ waste gas cracking” process. Regenerated carbon retains 90% of original performance and costs 50% less than new carbon. We also provide free waste carbon pickup for clients in the Yangtze River Delta and Europe (via our Rotterdam office).
6. How can I verify the quality of your activated carbon before placing a large order?
We provide three quality assurance steps:
- Sample testing: Free 1kg samples (with test reports) for you to validate performance (e.g., VOCs removal efficiency, heavy metal leaching).
- Third-party certification: We share reports from SGS or Intertek upon request.
- On-site support: For bulk orders, our engineers can conduct on-site performance tests (e.g., in your spray booth or water treatment system).
7. What sustainability measures do you take in production?
We prioritize eco-friendly practices:
- Carbon reduction: Our Datong base uses heat recovery systems to cut coal consumption by 15% (3,200 tons of annual CO₂ savings).
- Water recycling: 80% of production water is treated and reused via our wastewater recycling plant.
- Long-term goals: We aim for carbon neutrality at Tianjin and Wuxi bases by 2030, and our recycled carbon reduces landfill waste by 80% compared to disposable options.
8. What if the activated carbon does not perform as expected in my application?
We offer a 30-day performance guarantee. If the product fails to meet agreed-upon standards (e.g., VOCs removal <90% for honeycomb carbon), we will:
- Replace the product free of charge;
- Adjust the formula for custom orders;
- Provide on-site technical support to optimize usage (e.g., adjusting flow rate or installation).
