Powdered activated carbon
Overview Powdered Activated Carbon (PAC) is a finely ground adsorbent material derived from high-quality raw sources such as coal, wood, or coconut shells. It features a vast internal surface area for efficient removal of impurities through adsorption. Available in standard, food-grade, and pharmaceutical-grade variants, PAC supports diverse industrial purification needs while meeting global compliance standards.
Features
- High adsorption capacity for organic compounds, dyes, and micropollutants.
- Fine particle size for rapid dispersion and enhanced contact in liquid systems.
- Low ash and moisture content to minimize impurities in end products.
- Compatible with coagulation and flocculation processes in water treatment.
- Available in grades compliant with AWWA B600, EN 12903, NSF/ANSI 61, FCC, and USP.
Applications
- Water Treatment: Removes taste, odor, organic compounds, and micropollutants from drinking and wastewater.
- Food & Beverage: Decolorization, deodorization, and purification in sugar, juices, wine, and edible oils.
- Pharmaceuticals & Chemicals: API purification, catalyst support, and removal of contaminants in fine chemicals.
- Air Purification: Specialty grades for VOC and odor control in gas-phase systems.
Advantages
- Fast adsorption kinetics and wide pH compatibility (typically 3-11) for versatile use.
- Cost-effective contaminant removal with minimal dosage requirements.
- Enhances process efficiency in coagulation/flocculation for water systems.
- Supports regulatory compliance, enabling export to global markets.
- Eco-friendly reactivation potential for sustainable operations.
