Chemically Activated
Activated Carbon Powder is a microporous substance made from carbonaceous raw materials such as wood, coconut shells, rice husk, and so on. The activation process creates a plethora of pores with molecular dimensions within the carbon, resulting in a massive interior surface area. The carbon atoms on Activated Carbon's internal surfaces exert pressure on the molecules of the surrounding gases and liquids. This forces’ strength is proportional to the molecular structure of the surrounding medium. This is how Activated Carbon may be used to remove various components from a mixture.
Activated Carbon powders are used as purifying and decoloring agents in a wide range of processes. It absorb between 10 percent to 90 percent of its weight in impurities from an aqueous solution. Activated Carbon is introduced to the process liquor in an agitated vessel and filtered out after the appropriate contact time.
