Activated carbon is commonly used in water treatment to remove water contaminants from tap water and well water. Activated carbon is used in home water filtering system due to its excellent
carbon, several activated carbon filters are connected in series, be-cause then a maximum load in the first filter can be achieved. Impuri- ties which cannot be adsorbed in the first filter anymore are adsorbed in the next filters and therefore cannot return to the water cycle. The use of granular activated carbon in fixed bed filters also gives the possibility for thermal reactivation of the
Treatment of wastewater contaminated with phenol by activated carbon adsorption. One of the basic organic raw materials used today is phenol. Together with its derivative compounds, it can be found in all sorts of different industries such as paint manufacturing, phenolic resins production, ferrous industry, paper and pulp factories, etc.

DESOTEC’s activated carbon is often the appropriate technology for treatment at source as well as in between the various production stages, and for end-of-pipe treatment (e.g. after upstream biological or physicochemical treatment).
Activated carbon adsorption Adsorption is a process where a solid is used for removing a soluble substance from the water. In this process active carbon is the solid.
Activated Carbon Filter is widely accepted system in water filtration techniques. The treated water is free from chloramines (chlorine and ammonia mixture) and organic compounds; therefore, best for discharge and production use.

This solution guide addresses the key points a buyer should consider in developing filter specifications and selecting a supplier. Activated Carbon for Water Filtration Activated carbon has proven to be ideally suited to filter tastes, odors and contaminants from water. Activated carbon is a form of carbon that
Activated carbon is used in a broad range of applications for both industrial and residential uses that include drinking water purification, ground and municipal water treatment, power plant and landfill gas emissions, and precious metal recovery. Air purification solutions include VOC removal and odor control.
22 Water Conditioning & Purification JUNE 2006 T rihalomethanes (THMs) have been found to be the most wide-spread organic contaminants in drinking water.
Activated carbon filters absorb organic compounds and remove them from the water. These filters can remove These filters can remove volatile organic compounds, some pesticides, radon gas, hydrogen sulfide, mercury, and residual chlorine.
The activated carbon filter adsorbs vapors and binds them to the surface of the activated carbon. The zero odour level is reached by contacting the air through a bed of activated carbon in an adsorber.
Adsorption onto granular activated carbon (GAC) is an established technology in water and advanced wastewater treatment for the removal of organic substances from the liquid phase.
Activated Carbon Filter is used to adsorb chlorine, organics, tri-halo methane (THM), taste, odour, and colour from Water & Wastewater. Activated carbon is a charcoal that has been treated with oxygen to open up millions of tiny pores between the carbon atoms. The activated carbon has a massive surface area (2000 – 3000 square metres per gram of activated carbon) making it highly effective
materials to address any water treatment issue. Our high level of technical competence places Jacobi in the position of providing guidance regarding the choice and operating conditions of the activated carbon so that you achieve the best performance. Customers are also helped with recycling and reusing spent carbon at our reactivation locations, and Jacobi provides filter services as well as
Calgon Carbon is an acknowledged leader in the activated carbon and reactivation industry for many liquid and vapor phase applications, with complementary expertise in ultraviolet disinfection and oxidation, ion exchange technology, and ballast water treatment.
Uses. Activated carbon is used in methane and hydrogen storage, air purification, decaffeination, gold purification, metal extraction, water purification, medicine, sewage treatment, air filters in gas masks and respirators, filters in compressed air, teeth whitening, and many other applications.
A common form of mixed-media filter may contain fine sand as a pre-filter to remove larger particles in the water, then some form of activated carbon to remove odors and other compounds followed by a micro-screen filter that may contain bacteriostatic control agents. Most point-of-use water treatment devices sold in home supply and hardware stores contain mixed-media filters.
The specific capacity of a granular activated carbon to adsorb organic compounds is related to: molecular surface attraction, the total surface area available per unit weight of carbon, and the concentration of contaminants in the wastewater stream.

Because of stringent effluent standards, many drinking-water treatment applications will require replacement with virgin carbon, particularly for weakly adsorbing compounds such as MTBE.
Depending on the type of water, suspended solids concentration, oil and grease, COD, BOD and pesticides contents, activated carbon filters are sized differently, but the basic design data to clarify natural waters is the following:
Carbon filtering is commonly used for water purification, in air purifiers and industrial gas processing, for example the removal of siloxanes and hydrogen sulfide from biogas.
