Powdered activated carbons, also known as PAC is a form of product containing small particles of activated carbon with a particle size between 50 (in other grinding processes also 0.1) and up to 200 µm. They are produced by crushing and very fine grinding of activated carbon. Grain sizes in the range of a few micrometers are common. Thanks to their porous structure, powdered activated carbons achieve very high specific surface areas.

In addition to drinking water treatment, exhaust air treatment and in the food industry, this product can be especially used for flue gas cleaning. It can be used particularly well to remove micropollutants such as pharmaceuticals, hormones, biocides and much more by attaching them to the powdered activated carbon.
