Activated Carbon Purchase Recommendations
Choose the iodine value based on your needs: For efficient removal of trace organic matter or heavy metals, prioritize products with an iodine value ≥1000 mg/g.
For removal of large molecular pollutants or decolorization, products with an iodine value of 800–900 mg/g are sufficient.
Pay attention to particle size and uniformity: Granular activated carbon (e.g., 0.5–2 mm) is suitable for fixed-bed filtration systems, offering good flowability and low pressure drop.
Uniform particle size improves adsorption efficiency and reduces the risk of bed clogging.
Verify product certifications: Choose products with international certifications such as NSF and ISO to ensure compliance with drinking water safety standards.
Consider cost-effectiveness: High-iodine-value coconut shell activated carbon is more expensive, but it has a longer lifespan and higher adsorption efficiency, potentially resulting in lower long-term costs.
You can balance performance and price based on your budget and needs; for example, choosing a product with an iodine value of 900–1000 mg/g can be a compromise.
