Powdered Activated Carbon (PAC)

Coal-Based Powdered Activated Carbon (PAC) – Rapid Adsorption for Liquid Phase Treatment

Raw Material: Bituminous Coal / Lignite

Applications: Water Treatment, Wastewater Treatment, Decolorization, Emergency Contaminant Removal

Keywords: Powdered Activated Carbon, PAC, Water Treatment Carbon, Decolorization Carbon, COD Reduction, Wastewater Treatment Carbon

Product Overview

Coal-based Powdered Activated Carbon (PAC) is widely used in liquid-phase treatment processes for the adsorption of dissolved organic compounds, color-causing substances, taste and odor compounds, and trace contaminants.

Due to its fine particle size and large external surface area, PAC can be dispersed directly into water treatment processes, allowing rapid contact between the carbon and contaminants. The material is commonly used in municipal water treatment plants, industrial wastewater systems, decolorization processes, landfill leachate treatment, and emergency treatment applications.

Different grades are available according to adsorption requirements, particle size distribution, and target contaminants.

Key Features

Fine Particle Size

The small particle size provides a short diffusion path and rapid adsorption characteristics, making PAC suitable for applications requiring relatively short contact times.

Organic Contaminant Removal

PAC is commonly used for removal of dissolved organic compounds that contribute to color, odor, taste, and elevated COD levels.

Process Flexibility

The carbon can be introduced directly into process tanks, mixing basins, clarifiers, or treatment trains without the need for fixed adsorption vessels.

Compatibility with Existing Systems

PAC is frequently incorporated into existing treatment processes as a supplemental treatment step during seasonal events, process upsets, or temporary increases in contaminant loading.

Broad Application Range

Suitable for municipal, industrial, environmental remediation, and specialty treatment applications.

Industrial Wastewater Treatment

Applied for adsorption of dissolved organic compounds and refractory pollutants that may contribute to elevated COD levels.

Decolorization Processes

Used in textile, sugar, food processing, chemical, and pharmaceutical industries to reduce color in process streams and wastewater.

Landfill Leachate Treatment

Can be incorporated into treatment systems to reduce dissolved organic carbon and selected organic contaminants.

Groundwater Remediation

Used in pump-and-treat systems and other remediation processes involving hydrocarbon-contaminated groundwater.
