Activated carbon treatment in water treatment plants is often installed to remove natural organic compounds, taste and odor compounds, and synthetic organic chemicals.
Activated carbon adsorption physically binds the molecules of the gas or liquid phase to the surface of the carbon. Commonly used adsorption processes use CAG Granular Activated Carbon and CAP Activated Carbon in pellet (pellet). 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 water filtration or pretreatment of reverse osmosis membranes to adsorb. Because this type of GAC column is used in an organic compound adsorption mode, the carbon can be periodically regenerated or replaced by a Reactivation process once depleted.
Activated carbon applications:
Charcoal for water and liquids:
Treatment of municipal drinking water (elimination of flavors, odors and micro-pollutants, for example, pesticides, detergents ...),
Domestic water treatment (in-line and cartridge filters),
Industrial process water (dechlorination and deozonation),
Recovery of contaminated groundwater.
Wastewater treatment - tertiary treatment (elimination of organic traces and COD, deodorization and discoloration, spraying as a bioflocculation improvement in an aerobic or anaerobic biological wastewater treatment plant, additional for physical-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 (removal of solvents and hydrocarbons, deodorization, air conditioning, dioxin removal, kitchen hoods, combustion gases (not solid), mercury and other trace elements in combustion gases).
Cleaning process gases (removal of hydrogen pollutants, natural gas, carbon dioxide, landfill gas, solvent recovery ...)
Respiratory protection (gas masks or respirators, elimination of harmful toxic compounds),
