Activated Carbon

Activated Carbon is the best general use adsorbent to remove/reduce a lot of organic and some inorganic contaminants found in different liquid and gas products. Activated carbon has the unique ability to adsorb a wide range of compounds from both the liquid and gas phase. This adsorptive feature is responsible for removing contaminants from water and other substances where the adsorbent material is added. Activated Carbon features a highly crystalline form with a wide surface area and extensively developed internal pore structure. Surface area is used as a primary indicator of the activity level, based on the principle that the greater the surface area, the higher the number of adsorptive sites available. Application of high temperatures in the presence of a controlled flow of steam used as the oxidizing medium is what “activates” carbon and produces pore structure. Pore size distribution defines the performance of the material. It is defined as follows: Micro pores r < 1nm

Meso pores r 1-25nm
Macro pores r > 25nmThe macro pores are used as the entrance to the activated carbon, the meso pores for transportation and the micro pores for adsorption. Different types of Activated Carbons can be produced with specific characteristics depending upon the raw material and activation technique used in their production .

Apelsa CCA-700 activated carbons are products that feature high capacity for contaminants adsorption. Manufactured from coconut shell they present an optimum micropore volume, which is ideal for small molecules removal.

Apelsa CCA-700 Activated Carbons offer excellent results in water dechlorination and organic compounds removal, such as solvents and phenolics produced as a result of animal and plant rotten residues. They are also used to remove trihalomethanes formed as reaction between free chlorine and organic material dissolved in water that are cancer agents.

Other applications are: medicinal...
