GRANULAR ACTIVATED CARBON (GAC) FACT SHEET

The use of granular activated carbon (GAC) for water purification became common around the start of the 20th century (1906) when the "activation" process was applied to charcoal (which had been used for centuries). Thermal activation of charcoal greatly improves its pore volume, surface area and

What Is Activated Charcoal and How Does it Work?

Activated charcoal is carbon that has been treated with oxygen.The treatment results in highly porous charcoal. These tiny holes give the charcoal a surface area of 300-2,000 m 2 /g, allowing liquids or gases to pass through the charcoal and interact with the exposed carbon. The carbon adsorbs a wide range of impurities and contaminants, including chlorine, odors, and pigments.

Water Processing using Activated Carbon

Activated Carbon. Activated carbons (granular and powdered) can be used to remove chlorine and chloramines along with other organic contaminants and particles to help ensure water meets process requirements.Catalytic activated carbons provide faster reaction rates than conventional carbons, requiring smaller adsorption equipment and less carbon in use.

Activated Carbon - Agricultural Marketing Service

Adsorption is the most studied of these properties in activated carbon. Most food processing applications of activated carbon can be characterized by the adsorption that occurs when components of a liquid (the food or beverage) attaches to a solid (activated carbon). This can be either physical or chemical in nature, and frequently involves both.

Manufacturing - Carbon Activated Corporation

Activated carbon is produced from coconut shells, wood, coal and other carbonaceous sources. During the activation process, pure carbon is extracted from these materials by a superheating method known as pyrolysis. Throughout the manufacturing process, samples are collected at various stages and tested for quality in our labs.

Adsorption / Active Carbon - Lenntech

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 is produced specifically so as to achieve a very big internal surface (between 500 - 1500 m 2 /g). This big internal surface makes active carbon ideal for ...
