Coal-based granular activated carbon For Sewage Treatment
Raw Material: Bituminous Coal / Anthracite
Applications: Municipal Wastewater Treatment, Industrial Effluent Treatment, Biological Activated Carbon (BAC) Systems
Keywords: Coal GAC, Wastewater Activated Carbon, Municipal Sewage Treatment, Industrial Effluent Treatment, BAC Filter Media, COD Reduction, BOD Reduction
Product Overview
Coal-based Granular Activated Carbon (GAC) is widely used in municipal and industrial water treatment systems for the removal of dissolved organic compounds, color, odor-causing substances, and trace contaminants.
Produced from selected coal feedstocks, the material develops a pore structure containing both micropores and mesopores, allowing adsorption of a broad range of organic molecules commonly found in wastewater streams. Its mechanical strength makes it suitable for fixed-bed filters, deep-bed adsorption systems, and Biological Activated Carbon (BAC) applications that require periodic backwashing.
Different grades can be supplied according to adsorption requirements, hydraulic loading conditions, and target contaminant characteristics.
Key Features
Mesoporous Structure for Organic Removal
The pore size distribution supports adsorption of larger organic molecules such as humic substances, dyes, proteins, and other dissolved organics frequently encountered in municipal and industrial wastewater.
Mechanical Durability
High hardness and abrasion resistance help reduce media loss during hydraulic transport and backwashing operations.
Compatibility with BAC Systems
The carbon surface provides a suitable environment for microbial colonization, allowing adsorption and biological degradation processes to occur simultaneously in BAC applications.
Hydraulic Performance
Appropriate particle sizing supports water flow distribution while maintaining acceptable pressure loss within filtration systems.
Regeneration Potential
Depending on contaminant loading and operating conditions, spent carbon may be suitable for thermal reactivation or replacement programs.
