NINGBO INNO PHARMCHEM CO.,LTD. offers a diverse range of activated carbon products, catering to various industrial needs. Among these, our coal-based columnar activated carbon has gained significant recognition for its outstanding performance in water treatment and other purification applications. While other sources like coconut shell and wood also produce activated carbon, understanding the differences is key to selecting the most suitable material for your specific requirements.

Coal-Based Activated Carbon: The Industrial Workhorse

Our coal-based activated carbon is derived from high-quality anthracite. This source material provides a unique advantage in terms of pore structure and hardness. The key characteristics that make it particularly effective for industrial water purification include:

  • Developed Micropore Structure: Anthracite-based activated carbon typically possesses a highly developed microporous structure, which is exceptionally effective at adsorbing small organic molecules, chlorine, and compounds that affect taste and odor in water. This is reflected in its high iodine values, often exceeding 900 mg/g.
  • High Mechanical Strength: Coal-based activated carbon generally exhibits superior mechanical strength compared to wood-based alternatives. This durability is crucial for applications where the carbon is subjected to pressure, attrition, or requires long service life, such as in large-scale water filters and industrial reactors.
  • Cost-Effectiveness: While performance is paramount, the availability and cost-effectiveness of anthracite make coal-based activated carbon a highly competitive choice for bulk applications like bulk activated carbon for water treatment.

Comparing with Other Sources:

  • Coconut Shell Activated Carbon: This material is renowned for its extremely high percentage of micropores and high hardness, making it excellent for high-purity water applications and gas-phase adsorption. However, it is generally more expensive than coal-based options.
  • Wood-Based Activated Carbon: Wood-based activated carbon typically has a higher proportion of mesopores and macropores, making it suitable for adsorbing larger molecules and for decolorization. It is often less hard than coal or coconut shell activated carbon.

When to Choose Coal-Based Activated Carbon:

For applications requiring robust performance, excellent adsorption of organic contaminants and chlorine, and a balance of cost and durability, coal-based columnar activated carbon is often the preferred choice. It is ideal for:

  • Municipal drinking water purification
  • Industrial wastewater treatment
  • Process water purification
  • Sewage treatment
  • General odor and taste removal
