Usage of Coal Activated Carbon Powder: Broad Applications

Coal can be processed into various granular, pellet, and powder forms of activated carbon. The most cost-effective option, with low competition, high sales volume, and sufficient supply, is coal-based activated carbon powder. This powder finds broad applications.

Waste Incineration

In the past, methods such as landfilling and incineration were used for waste disposal. However, due to the environmental damage caused by these methods, waste incineration has been applied since 1990. However, the cost of waste disposal has increased.

• Emission Standards:
  • Dioxin: 0.1 Ng
  • Mercury: 0.05mg"/Nm3
  • Cadmium: 0.1mg"/Nm3
  • Lead: 1mg"/Nm3
  • SO2: 20mg"/Nm3
  • CO: 50mg"/Nm3
  • HCL: 250mg"/Nm3
  • HF (Hydrogen Fluoride): 80mg"/Nm
• Substances Formed After Waste Incineration:
  • Ammonia
  • Nitrogen oxides
  • Dioxins (kitchen waste)
  • Metals (Fe, Pb, Cr, Hg, Cu)
  • Sulfur, hydrogen, HCL (leather)
  • HF (rubber)

Carbontech carbon can absorb various waste gases by providing activated carbon with a high iodine value.

Wastewater Treatment

In industrial wastewater treatment, coal activated carbon powder is often added to biological treatment pools. This is used in addition to bacteria and COD. Flow balancing tanks are found in wastewater treatment plants and are designed to optimise the efficiency of the treatment process. Activated carbon is used to neutralise the pH of wastewater. For example, it effectively treats acidic wastewater containing phenolic pollutants, cresol, and ethyl phenol.

• Effects of Coal Activated Carbon:
  • COD content: 300-400mg"/l → <80mg"/l
  • Ammonia nitrogen content: 300-400mg"/l → <25mg"/l

Urban Sewage Treatment and Water Facilities

Coal activated carbon powder is used in urban sewage treatment plants and water facilities for processes such as removing organic matter (humic acid), adjusting pH, removing residual chlorine, reducing turbidity, lightening colour, and removing heavy metals.
