Advanced adsorption with bacteriostatic protection inside the filter bed
ACTIVESORB®-AG is a high-activity, silver-impregnated granular activated carbon manufactured from selected coconut shells.
Steam activation develops an extensive microporous structure for reducing chlorine, taste, odor, color and selected dissolved organic impurities. The silver incorporated into the carbon provides bacteriostatic properties that help inhibit bacterial colonization and biological growth on the filter media. High hardness, optimized density and low dust support clean, reliable operation in point-of-entry, point-of-use, residential, food and beverage, and specialized water-purification systems.
Cleaner water / More hygienic filter-media operation
Adsorption and bacteriostatic protection.
Across critical water applications.
ACTIVESORB®-AG is intended for systems in which conventional activated-carbon adsorption is required and uncontrolled biological growth on moist filter media may become a concern.
Drinking-Water Purification
Reduction of chlorine, taste, odor, color and selected adsorbable organic impurities.
Point-of-Entry Systems
Whole-building activated-carbon filtration with bacteriostatic protection of the media bed.
Point-of-Use Purifiers
Compact cartridge and under-counter water-purification applications.
Food and Beverage Processing
Treatment of process water for beverages, dispensers and food preparation.
Pharmaceutical Water Systems
Polishing applications where hygienic media operation is important and system validation is provided.
Dispensers and Specialty Equipment
Water coolers, coffee machines, laboratory polishing units and aquarium-treatment systems.
Four protective functions engineered into one carbon media
Bacteriostatic Media Protection (SILVER-GUARD™)
Trace silver incorporated into the carbon helps inhibit bacterial colonization and biological growth on the surface of the filter media.
High-Activity Micropore Adsorption (MICROPORE-AG™)
Steam-activated coconut-shell carbon provides an extensive microporous surface for adsorption of taste, odor, color and selected dissolved organic compounds.
Rapid Dechlorination (CHLOR-CAPTURE™)
High-activity carbon surfaces support rapid free-chlorine reduction when adequate contact time and appropriate operating conditions are provided.
Hard, Low-Dust Granules (CLEAN-BED™)
High ball-pan hardness, optimized density and low dust help reduce particle breakdown and support clearer filter startup and stable fixed-bed operation.
Science & Technology
ACTIVESORB®-AG combines physical adsorption by activated carbon with the bacteriostatic action of trace silver on the media surface.
- Steam-Activated Coconut Shell – Selected coconut shells are steam activated under controlled conditions to develop high internal surface area and a predominantly microporous structure.
- Adsorption within Micropores – Organic molecules and taste- and odor-causing compounds diffuse into the carbon’s pore network, where intermolecular forces retain them on the internal surface.
- Silver-Based Bacteriostatic Action – Silver ions can interfere with microbial enzymes, membranes and replication processes, inhibiting bacterial colonization of the carbon media.
- Dual-Function Filter Protection – The carbon reduces adsorbable contaminants while the silver helps control growth on the media, supporting more hygienic filter-bed operation.
