Powdered Activated Carbon

Powdered Active Carbon (PAC) is a fine grinding active carbon with generally 10-150 micrometers in diameter – much less than the granular or granulated active carbon. It is made from a wide range of raw materials such as coal, timber, coir, and peat, which are treated by carbonation and activation to create an extensive inner surface area and high availability of pore net optimized for fast adsorption dynamics.

The distinctive feature of PAC is that it has a very high outer surface area compared to the size of the grain. This physical characteristic allows for very rapid contact with the surface of the carbon with its surrounding fluid or gas phase pollutants, which is why PAC is one of the most flexible and flexible sorbent forms available. In contrast to the fixed bed granules, PAC is usually injected directly into the process flow – the water-treating basin, the mud reactor, or the exhaust pipe – and then, once the absorption has been finished, the separation is performed by settling, filtering, or coprecipitation. Such a flexible dosage allows PAC to be particularly suitable for applications where there is a need for a quick reaction, a change in the processing strength, or a short time limit for the use of a fixed bed.
