Applications
Coal-based activated carbon excels in a variety of industrial and environmental scenarios, leveraging its unique pore structure for effective removal of contaminants. Key applications include:
- Water Treatment and Purification: Ideal for municipal and industrial water systems to remove organic compounds, chlorine, pesticides, and taste/odor issues. It effectively reduces total organic carbon (TOC) in drinking water and wastewater, ensuring compliance with global health standards.
- Air and Gas Purification: Used in HVAC systems, industrial exhaust filters, and respiratory masks to adsorb volatile organic compounds (VOCs), odors, and harmful gases like hydrogen sulfide.
- Industrial Processes: Applied in food and beverage decolorization, pharmaceutical purification, solvent recovery, and gold mining for cyanide removal.
- Environmental Remediation: Effective for groundwater cleanup, landfill leachate treatment, and soil vapor extraction, addressing pollutants like PFAS and heavy metals.
- Other Uses: In agriculture for soil amendment, medical applications for poison control, and energy storage in supercapacitors.
