Activated carbon treatment in water treatment plants is usually installed to remove natural organic compounds, taste and odor compounds and synthetic organic chemicals.
Adsorption with activated carbon physically binds the molecules of the gas or liquid phase to the carbon surface. Commonly used adsorption processes are CAG Granular activated carbon and CAP Pelleted activated carbon. Activated carbon is an effective adsorbent because it is a highly porous material and provides a large surface area to which contaminants can chemically adhere.
The most common use is in bed columns for process water filtration or reverse osmosis membrane pretreatment for adsorption. Because this type of GAC column is used in an organic adsorption mode, the carbon can be periodically regenerated or replaced by a Reactivation process once depleted.
Activated carbon applications
Carbon for water and liquids
Municipal drinking water treatment (removal of tastes, odors and micropollutants, e.g. pesticides, detergents…),
Domestic water treatment (in-line and cartridge filters),
Industrial process water (dechlorination and deozonation),
Recovery of contaminated groundwater.
Wastewater treatment – tertiary treatment (removal of trace organics and COD, deodorization and decolorization, spraying as bioflocculation enhancement in an aerobic or anaerobic biological wastewater treatment plant, additional for physico-chemical treatments).
Purification of raw materials (purification of oils and fats, alcoholic and non-alcoholic beverages, colorants, decolorization of sugar and glucose, food, chemicals, pharmaceuticals) and catalytic processes.
Carbon applications for air and gases:
Air purification and environmental protection (solvent and hydrocarbon removal, deodorization, air conditioning, dioxin removal, stove hoods, flue gas (non-solid), mercury and other trace elements in flue gas).
Cleaning process gases (removal of hydrogen pollutants, natural gas, carbon dioxide, landfill gas, solvent recovery…)
Respiratory protection (gas masks or respirators, elimination of noxious toxic compounds),
