Coal-Based Powdered Activated Carbon (PAC) – Rapid Adsorption for Liquid Phase Treatment
Product Name: Coal-Based Powdered Activated Carbon (PAC)
Raw Material: Premium Bituminous Coal / Lignite
Keywords: Powdered Activated Carbon, PAC, Liquid Phase Carbon, Water Decolorization, COD Reduction, Fast Kinetics
Product Overview
Achieve rapid and efficient purification with our Coal-Based Powdered Activated Carbon (PAC). Designed specifically for liquid-phase applications, this fine powder offers an extensive surface area and immediate contact with contaminants, providing fast adsorption kinetics that granular carbons cannot match.
It is the preferred solution for seasonal water treatment, emergency spill response, and industrial decolorization. Its ability to be dosed directly into process streams makes it a versatile and cost-effective choice for removing organic pollutants, color, and taste issues without the high capital investment of fixed-bed systems.
Key Advantages
- Rapid Adsorption Kinetics: The fine particle size (typically 200-325 mesh) ensures a short diffusion path, allowing for almost instantaneous removal of contaminants.
- Excellent Decolorization: Highly effective at removing dissolved organic color bodies, humic acids, and synthetic dyes from liquids.
- Flocculation Aid: Acts as a coagulant aid, improving the settling of suspended solids and enhancing the overall clarification process.
- Operational Flexibility: Can be easily added to existing tanks or slurries and adjusted based on fluctuating contaminant loads, offering a low-capital solution for water treatment.

Applications
Municipal & Industrial Water Treatment:
Ideal for seasonal taste and odor control (e.g., algae blooms) and emergency contaminant removal. It is dosed directly into the intake or mixing tanks and removed during sedimentation/filtration.Wastewater Treatment (COD/BOD Reduction):
Used to polish effluent by adsorbing refractory organic compounds, significantly lowering Chemical Oxygen Demand (COD) to meet discharge standards.Industrial Decolorization:
Widely used in the textile, sugar, and chemical industries to remove color from process streams, syrups, and effluents.Groundwater & Soil Remediation:
Effective in pump-and-treat systems for adsorbing petroleum hydrocarbons and solvents from contaminated groundwater.Landfill Leachate Treatment:
Treats high-strength leachate by removing dissolved organic carbon and heavy metals.
Packaging & Storage
- Packaging: 25kg multi-wall paper bags or 500kg/1000kg bulk bags (jumbo bags).
- Storage: Store in a cool, dry area. As a powder, it requires protection from humidity to prevent caking and from strong drafts to prevent dusting.
