Product Overview

Produced from high-quality bituminous coal through extrusion forming, high-temperature steam activation and impregnation processing, ARC-AL balances basic physical adsorption capacity with targeted chemical neutralization for ammonia and amine odors. Its 4mm cylindrical shape ensures uniform gas flow through packed beds with manageable pressure drop, making it easy to scale for large deodorization systems.

With >50% CTC base carbon performance and >800 m²/g BET surface area, it effectively handles co-occurring organic odors alongside alkaline gases. The >90% abrasion resistance ensures low dust generation and stable operation over the service life, making it a cost-effective workhorse for routine municipal and agricultural odor control projects where budget efficiency is a priority.

Key Features

Cost-Optimized Impregnation Formula
Engineered for budget-sensitive odor control projects, delivering reliable ammonia and low-concentration amine removal at a lower total media cost than premium impregnated grades.
Uniform 4mm Extruded Column Structure
Consistent cylindrical shape ensures even gas distribution across packed beds, preventing channeling and premature breakthrough in fixed-bed deodorization systems.
High Mechanical Integrity (>90% Hardness)
Robust coal-based construction resists particle breakage during pneumatic loading and continuous airflow operation, minimizing dust carryover to downstream equipment.
Stable Base Carbon Adsorption (CTC >50%)
Steam-activated base carbon with >800 m²/g surface area provides dependable physical adsorption capacity for co-existing organic vapors alongside alkaline odor compounds.
Predictable Bed Packing (780–820 kg/m³)
Narrow bulk density range simplifies vessel fill calculations and ensures stable hydraulic performance across standard filter housing designs.

Applications

Light-Load Ambient Odor Control: Wastewater pumping stations and primary settling tanks generate low-concentration ammonia odors where premium-grade carbon would be over-engineered. ARC-AL's balanced impregnation delivers dependable alkaline gas removal at an accessible cost point for large-volume installations.
Poultry & Livestock General Ventilation: General ventilation systems in poultry houses and barns require cost-effective ammonia control across large air volumes. ARC-AL provides chemical neutralization for alkaline odors without the premium pricing of high-activity grades.
Fertilizer Storage Fugitive Emissions: Fertilizer storage and handling areas produce low-level ammonia fugitive emissions. ARC-AL's acid-impregnated surface captures these intermittent alkaline vapors to maintain workplace air quality.
Light Chemical Processing Odor: Facilities handling low-concentration amine-based process chemicals need routine odor control. ARC-AL offers a budget-efficient solution for ambient alkaline gas treatment.
