Activated carbon has over 2,500 commercial product applications. Most wastewater treatment plants use carbon to purify the water and air leaving the facility. But you won't find their characteristics and properties in a "formal" education. You learn about them on the job. Activated carbon is an inert solid adsorbent material  commonly used to remove a variety of dissolved contaminants from water and process gas phase streams. It is made from virtually all carbon-containing raw materials, including coconut shells and members of the coal family, as many readers already know. Adsorption is the accumulation of a gas or liquid on the surface of a liquid or solid substrate, as opposed to absorption, in which an invasive substance enters the volume or volume of the substrate. Activated carbon is porous, inexpensive and easy to use as an adsorbent, providing a large surface area to remove contaminants. It has a greater useful surface area per gram than any other material availabl...

Granular Activated Carbons are a very versatile group of adsorbents, with capability for selectively adsorbing thousands of organic, and certain in- organic, materials. From medicinal uses of powdered carbons in ancient Egypt, through charred interiors of whiskey barrels, carbon has been activated and used as an adsorbent for centuries. Granular vapor phase activated carbon  media was first widely used in WWI military gas masks and, in the years between World Wars, commercially in solvent recovery systems. Granular liquid phase activated carbons achieved their first prominent applications following WWI’, in sugar de-colorization and in purification of antibiotics. Today, there are hundreds of applications — if diverse uses under the general heading of environmental control are counted separately, ongoing applications number in the thousands Adsorption/Adsorbents/Granular Activated Carbon Since adsorption is a comparatively specialized technology, a capsule definition of terms may b...

Activated charcoal can be made from a variety of carbon-rich materials such as wood, coal, bone, coconut shells, nut shells, peat and agricultural residues. The pore properties and adsorption capacity of activated carbon depend on the type of raw material used for its production. It also depends on the method used for its activation. Black bone charcoal is the one with the lowest adsorption capacity, while gray-brown bone charcoal is the best. White carbon exhibits a low capacity for fluoride removal. The surface area of these bone carbons is usually lower than that of activated carbon. However, they have high adsorption of certain metals such as copper, zinc and cadmium. Activated carbon produced from nut shells and coconut shells  has the best adsorption capacity and the largest surface area. Even if you use hardwood, the procedure is the same, but using coconut shells produces a high quality activated carbon. ▴ Coconut shells (without meat) ▴ Burn sinks, drums or slender iron co...
