Component Specifications

Definition
Activated carbon media is a highly porous carbon-based material with an extensive internal surface area, typically derived from sources like coconut shells, coal, or wood. It functions as the core filtration element in activated carbon filters, utilizing physical adsorption and chemical reactions to capture and remove organic compounds, chlorine, odors, and various chemical contaminants from liquids and gases in industrial processes.
Working Principle
The working principle relies on adsorption, where contaminant molecules are trapped within the vast network of pores on the carbon surface due to van der Waals forces and chemical interactions. The high surface area (typically 500-1500 m²/g) provides numerous active sites for capturing impurities as fluid passes through the media bed.
Materials
Activated carbon derived from coconut shell, coal (bituminous or lignite), wood, or peat; may be impregnated with chemicals like potassium permanganate for enhanced removal of specific contaminants; available in granular (GAC), powdered (PAC), or extruded pellet forms.

Frequently Asked Questions

What is the difference between GAC and PAC activated carbon media?

GAC (Granular Activated Carbon) has larger particle sizes (0.2-5 mm) and is used in fixed-bed filters for continuous flow applications. PAC (Powdered Activated Carbon) has finer particles (<0.18 mm) and is typically added directly to process streams for batch treatment or emergency contaminant removal.

How often should activated carbon media be replaced?

Replacement frequency depends on contaminant loading, flow rates, and media capacity. Typically, industrial systems require replacement every 6-24 months, based on pressure drop increases, breakthrough monitoring, or scheduled maintenance protocols.

Can activated carbon media be regenerated?

Yes, thermal regeneration at high temperatures (800-1000°C) in controlled atmospheres can restore adsorption capacity, but this is typically done off-site by specialized facilities due to equipment requirements and potential media loss.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
