Fermentation: Removal of unwanted color compounds is an example of an application of activated carbon and resins in citric acid production. The decolourisation of extracts used in the lactic acid production process is another fermentation process where activated carbon is commonly used.
Activated carbon, also called activated charcoal, is a form of carbon processed to have small, low-volume pores that increase the surface area available for adsorption or chemical reactions. Activated is sometimes replaced by active.. Due to its high degree of microporosity, one gram of activated carbon has a surface area in excess of 3,000 m 2 (32,000 sq ft) as determined by gas adsorption.
The performance of activated carbon in removing such organic compounds has been proven. Activated carbon filters used for water treatment in homes are usually made of either powdered activated carbon (PAC) or granular activated carbon (GAC). PAC is made of powdered carbon with a particle size of <0.18 mm and diameter in the range of 0.25–1.15 mm.

Activated carbon is created during the coal production process. Powdered activated carbon is typically ground and then sized to specified requirements. Activated carbon is used in plating solutions, water and air purification, and even in toothpaste, mainly due to its adsorption properties. Screening activated carbon can be a simple process when separating out coarse fractions.
