Advanced adsorption and catalytic performance in one premium carbon media
ACTIVESORB®-CX is a high-activity granular activated carbon manufactured by steam activation of carefully selected coconut shells.
Its extensive micropore structure provides strong adsorption of taste- and odor-causing compounds, natural organic matter, low-molecular-weight organics and chlorinated by-products such as chloroform and trihalomethanes. Enhanced catalytic activity supports the reduction of chloramine and hydrogen sulfide under appropriately engineered operating conditions. High mechanical hardness, optimized density and extensive dedusting help deliver dependable filtration, low carbon fines and consistently clear treated water.
Catalytic treatment. Powerful adsorption. Cleaner filtration.
One activated carbon media.
Multiple treatment applications.
ACTIVESORB®-CX can be incorporated into fixed-bed pressure filters, gravity filters, point-of-entry systems and point-of-use equipment. Final media quantity, contact time, hydraulic loading and pretreatment must be selected according to the source-water analysis and treatment objective.
Municipal Drinking Water
Reduction of chlorine, chloramine, taste, odor and selected organic contaminants.
Point-of-Entry and Point-of-Use
Activated-carbon treatment for residential, commercial and institutional water systems.
Beverage Production
Improvement of process-water taste, odor and organoleptic quality.
Ion-Exchange Resin Protection
Reduction of oxidizing disinfectants before sensitive ion-exchange equipment.
Process and Ultrapure Water
Organic contaminant reduction upstream of advanced purification processes.
Wastewater and Water Reuse
Polishing of pretreated wastewater for color, odor and adsorbable organic compounds (includes swimming pools, aquariums, and industrial reuse).
Four treatment capabilities engineered into one carbon media
Catalytic Disinfectant Reduction (CATA-CX™)
Enhanced surface activity supports faster reduction of chlorine and chloramine than conventional non-catalytic activated carbon when sufficient contact time and suitable operating conditions are provided.
High-Capacity Organic Adsorption (MICROPORE™)
A developed micropore structure provides adsorption capacity for low-molecular-weight organic compounds, chloroform, trihalomethanes and other chlorinated by-products.
Hydrogen Sulfide Control (SULFIDE-GUARD™)
Catalytically active carbon surfaces support hydrogen sulfide reduction. Actual performance depends on concentration, pH, dissolved oxygen, contact time and competing contaminants.
Hard, Low-Dust Media (CLEAN-FLOW™)
High ball-pan hardness and extensive dedusting reduce carbon fines, improve handling and help maintain low treated-water turbidity.
Science & Technology
ACTIVESORB®-CX combines coconut-shell microporosity, steam activation and catalytic surface functionality to deliver adsorption and reduction of targeted contaminants.
- Steam-Activated Coconut Carbon – Selected coconut shells are steam activated to develop a highly porous internal structure without relying on conventional chemical activation agents.
- Micropore-Dominant Adsorption – The high micropore volume is particularly suited to adsorption of relatively small organic molecules and chlorinated organic by-products.
- Catalytic Surface Activity – Surface functionality accelerates chemical reduction of chlorine and chloramine. This performance mechanism is different from the physical adsorption of organic contaminants.
- Mechanical and Hydraulic Stability – High hardness, controlled grain sizes and optimized density support fixed-bed operation with reduced particle breakdown and manageable pressure loss.
