reactivation and regeneration of activated carbon

Carbon Regeneration Reactivation Recycling Spent Activated ...

Activated carbons are used in hundreds of different purification applications. In many cases, when the carbon is spent or the treatment objective is no longer being achieved, the spent carbons can be recycled via thermal reactivation, a process we refer to as Regen-Sys®. The main benefits of carbon regeneration …

Reactivation - Carbon Activated Corporation

Reactivated carbon is an efficient, cost-effective alternative to virgin activated carbon. Thermal reactivation and reuse have grown in popularity. You save money because reactivated carbon is much cheaper that virgin carbon.

Spent Carbon Reactivation and Recycling - Evoqua

The reactivation process recycles spent carbons into new activated carbon materials that continue to provide excellent performance in many treatment applications. Reactivation can be applied to carbons used in both liquid phase and vapor phase applications. Spent carbons can be segregated from other spent carbons and returned to the same customer for reuse, or pooled with other spent carbons and sold into other applications as a cost-effective alternative to virgin carbon.

Regeneration / Actived Carbon - Lenntech

Steam regeneration; This method is restricted to regenerating carbon which has only retained a few very volatile products. Thermal regeneration; By pyrolysis and burning off of adsorbed organic substances. In order to avoid igniting the carbon, it is heated to about 800 °C in a controlled atmosphere.

Carbon Regeneration - Mineral Processing & Metallurgy

The carbon reactivation circuit is series of unit processes designed to restore the activated carbon’s ability to recover precious metals from cyanidation circuit solutions. Since each circuit will be treating a unique solution, which will result in unique carbon fouling problems, the reactivation circuit design must consider several variables, which includes the preference of the plant operator.

Thermal Regeneration of Activated Carbon - EPA

Activated carbon Is a proprietary material and the specific physico- chemical reactions requisite to activation are considered to be well guarded trade secrets. Regeneration of spent activated carbon has been achieved using a variety of processes and techniques ranging from solvent extraction to high temperature pyrolysis.

Thermal reactivation of ammonia-tailored granular ...

Thermal reactivation with CO 2 or NH 3 at temperatures higher than 700 °C effectively restored the perchlorate adsorption capacity of ammonia-tailored carbon. In contrast, steam regeneration restored only a portion of the perchlorate adsorption capacity, and these distinctions were attributed to the change in surface chemistry that was induced by regeneration.

Reactivation Services | Cabot Corporation

Reactivation is the means by which spent carbon can be recycled and sold as new. Granular activated carbon (GAC) has an infinite reactivation characteristic, requiring just 10% make-up carbon to restore spent carbon to its original adsorptive capacity.

Activated Carbon and its Applications

reactivation and subsequent reuse of spent activated carbon and the recycling of activated carbon that is no longer amenable to regeneration or reactivation. This brochure provides a general overview of the manufacture, characteristics and the potential uses of activated carbon in …

Extending the life of activated carbon | Water Technology

May 15, 2014 · Up to 95 percent of the virgin activated carbon can be recovered and blended with new virgin carbon. Carbon reactivation is most applicable to larger commercial, municipal or industrial operations. A typical residential POE filter will not contain enough spent carbon for reactivation.

Carbon regeneration - Metso

Metso’s carbon regeneration systems utilize thermal regeneration technology. Some industries call the product “AC” for activated carbon. The process uses an indirect fired kiln to heat the activated carbon to 700°C, driving off the organic and inorganic contaminants. The system uses a recycle duct to improve energy efficiency.

Activated carbon - Wikipedia

The reactivation or the regeneration of activated carbons involves restoring the adsorptive capacity of saturated activated carbon by desorbing adsorbed contaminants on the activated carbon surface. Thermal reactivation [ edit ]

Washington, D.C. September 2000 Wastewater Technology …

Carbon regeneration is accomplished primarily by thermal means. Organic matter within the pores of the carbon is oxidized and thus removed from the carbon surface. The two most widely used regeneration methods are rotary kiln and multiple hearth furnaces. Approximately 5 to 10 percent of the carbon is destroyed in the regeneration process or lost during transport and must be replaced with virgin carbon.
