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 than virgin carbon. At our facilities, adsorbed organics are destroyed during the thermal process and the activated carbon’s adsorptive capacity is restored up to 95% of the original levels. New carbon is added to make up for any minor loss during the process and the rejuvenated carbon is returned to your plant and reinstalled. And you won’t need to worry about the long-term liability of disposal.

We have two reactivation plants, in California and New York, that meet stringent environmental standards. Our regeneration facility in California is NSF 61 Certified for reactivating carbon for drinking water purposes. We also handle disposal of spent activated carbon at these facilities.

Quality and Safety

For quality and safety reasons, we don’t accept any spent carbon until it has been tested and approved for reactivation. You can be sure that our reactivated carbon meets all the performance levels of the original carbon and is completely safe to handle and fully effective for use.

\n
• All regenerated products are put through the same QA testing process that we use for our virgin media
\n
• Your reactivated carbon is screened to your specified mesh size
\n
• The moisture content won’t exceed 5% by weight
\n
• Your spent carbon is kept separate, and custom reactivated; you get back the same activated carbon you sent for regeneration
\n

Stock Management Services

No need to store excess carbon at your plant. Our large warehouse facilities allow us to hold extra carbon stock for our customers for quick delivery to your premises. You can reuse your own carbon after having it reactivated, become part of a carbon pool, or start fresh with virgin carbon each time.

The Environment Wins, Too

Reactivation takes a waste product with potential liability and recovers it as a reusable asset

\n
• Reactivation produces only about 20% of the greenhouse gases generated in making virgin activated carbon
\n
• Activated carbon’s reactivation capability is nearly infinite so it needn’t end up in a landfill or incinerator

Coal based activated carbon is available in four different types of base material - bituminous, sub bituminous, anthracite, & lignite, consisting of micro, meso and macro pore structures. This unique pore distribution makes coal based activated carbon ideal to remove small to large molecular structures. Typical applications include but not limited to odor control in liquid & vapor phase applications, improve taste in liquids, liquid decolorization and purification of wastewater & potable water. Coal base carbon is also available in granular, extruded (Pelletized), and powder forms.

Applications

• Portable water purification
• Wastewater treatment
• Industrial air purification
• Purification of food and beverage
• Medical and pharmaceutical uses
• Automotive uses
• Chemical purification

Wood based activated carbon is produced from selected types of wood and sawdust. This type of carbon is produced by either steam or phosphoric acid activation. Most pores in wood based carbon are in the meso and macro pore region which is ideal for decolorization of liquids and water. Wood base carbon is primarily used in surface water and wastewater filters to remove organic impurities and to effectively remove larger molecular structures like MIB (2-Methylisoborneol) and Geosmin. Wood base phosphoric acid activation can yield carbon with a very high surface area, ranging from 1500-2500 m2/g. The product is available in granular, pelletized, or powder forms.

Applications

• Potable water purification
• Surface and wastewater treatment
• Food and beverage decolonisation
• Pharmaceutical industry
• Purification and decolonisation of edible oil 

Carbon Activated makes a variety of coconut shell-based, impregnated activated carbon, in standard and custom sizes, for applications where non-treated carbon may not be effective. Surface impregnation chemically modifies activated carbon through a fine distribution of chemicals and metal particles on the internal surfaces of its pores. This greatly enhances the carbon’s adsorptive capacity through a synergism between the chemicals and the carbon. And provides a cost-effective way to remove impurities from gas streams which would otherwise not be possible.

Application

• Water Treatment : Because of its antimicrobial/antiseptic properties, silver-impregnated carbon is an effective adsorbent for purification in earth-bound domestic and other water systems.
• Gas Purification : Impregnated activated carbon is used to treat flue gases in coal-fired generation plants and other air pollution control applications. Carbon can be specifically impregnated for removal of acid gases, ammonia and amines, aldehydes, radio-active iodine, mercury and inorganic gases such as arsine and phosphine. Carbon impregnated with metal-oxide targets inorganic gases including HCN, H2S, phosphine and arsine.

Powdered Activated Carbon (PAC) is similar to Granular Activated Carbon (GAC) as it is made from high quality coal, wood or coconut shell raw material. PAC is typically considered to have particles less than U.S standard 80 mesh size, which makes it ideal for water treatment. Our PAC is a reliable, economical water treatment option for taste and odor control and removal of organic compounds. The use of PAC is beneficial economically and environmentally, since it reduces operating costs, produces minimal waste sludge, allows for the conservation of resources, and provides superior water quality.

Carbon Activated Corp. PAC can be used by water treatment plants on either a regular basis or as needed by the season for taste, color and odor control or removal of organic chemicals. It is also built into air purification systems to adsorb volatile compounds and heavy metals, like mercury. Our activated carbon products are heavily used in the food and beverage industries as they are ideal for the removal of unwanted colors, tastes, and odors. Powdered Activated Carbon is effective in the removal of haze, odor, and decolorization in wine, modification of the taste of beer, and the purification and decolorization of gelatin. It is also utilized in purification and quality control of several other food and beverage products.

Catalytic carbon is a class of activated carbon used to remove chloramines and hydrogen sulfide from drinking water. It has all the adsorptive characteristics of conventional activated carbons, as well as the ability to promote chemical reactions

What are Chloramines?

Chloramines are added to water as an alternative to chlorine. They inhibit the formation of carcinogenic trihalomethanes (THMs) caused by the interaction of chlorine with organic plant materials.

Catalytic Carbon is Not Impregnated with Caustic Chemicals

Because catalytic carbons have no impregnates, you won’t have to worry about reduced organic odor capacity or the higher bed fire potential of the impregnated carbons. Catalytic carbon is created by altering the surface structure of activated carbon. It is modified by gas processing at high temperatures to change the electronic structure and create the highest level of catalytic activity on carbon for reducing chloramine and H2S in water. This added catalytic functionality is much greater than that found in traditional activated carbons. Catalytic carbon is an economical solution to treat H2S levels as high as 20 to 30 ppm. Catalytic carbon converts adsorbed H2S into sulfuric acid and sulfurous acid which are water soluble, so carbon systems can be regenerated with water washing to restore H2S capacity for less frequent physical change-outs.

Benefits

• More effective than conventional carbons; catalytic activity promotes a variety of chemical reactions
• Faster chemical reaction means less carbon and smaller equipment
• Non-Impregnated carbon eliminates worries about exothermic reaction, ignition temperature and toxic disposal
• On-site regeneration lowers operating costs and extends service life
• Can be recycled and reused through thermal reactivation
