Activated carbon is a medium made from the charcoal of carbonaceous material such as coconut or peat. Once processed, a single gram of activated carbon has an increased surface area of more than 3,000 m2 and a high degree of microporosity thanks to its complex structure of mostly carbon atoms.


Activated carbon works through the physical adsorption of contaminating organic compounds and chlorine.wholesale activated carbon Its large and microporous surface area exerts an attractive force to the molecules of contaminating substances causing them to adhere to the pore walls of the activated carbon.


Adsorption should not be confused with absorption. The first is the process of molecules, ions or atoms from a liquid or solid adhering to a surface, creating a film called an adsorbate. Absorption on the other hand, is a process of assimilation, when the molecules of one liquid are dispersed or dissolved throughout the bulk of another.


Granulated activated carbon has the advantage of being harder and more durable than powdered activated carbon. It is clean to handle and has the ability to extract impurities from large volumes of water.


Activated carbon has a negative electric charge which attracts the molecules of many  – but not all – contaminants. dxdcarbon  While some chemicals like sodium and nitrates pass right through an activated water filter, organic and carbon-based impurities are efficiently bound to the surface.


Yes, absolutely. In fact, activated carbon water filters remove chlorine very efficiently and can be operated at low cost.Typically filters that remove chlorine are described as appropriate for CTO removal – which means CTO filters remove chlorine, taste and odor.
