Activated carbon is widely employed as an adsorbent in environmental protection, food, medicine, chemical industry, energy and other fields due to its good physical and chemical properties and low price. However, the resulting large amount of saturated activated carbon is easy to release harmful substances in the high temperature environment.
This new reactor has two possible configurations and is very versatile, since it allows the regeneration of more than 100 kg. of activated carbon saturated with pollutants from different industries, such as: wastewater treatment, water purification, gas and liquid purification, metal recovery, food and beverage production, chemical and pharmaceutical industry, etc.

regenerate adsorbent are described in more detail in Section 1.4. Typical equipment life for carbon adsorbers is between 15 and 25 years. However, systems that handle waste gases that contain corrosive materials, such as hydrogen chloride or other acid gases, have shorter equipment life due to the impact of corrosion on the adsorber components.
----- Wastewater treatment with GAC consists of the carbon contact system and the carbon regeneration system. Activated carbon removes soluble organics from water in three steps. The first step is the transport of the dissolved substances to be removed (solute) through a surface film to the exterior surface of the carbon.
