Activated Carbon

Activated Carbon is a form of carbon, often fromĀ charcoal, that has been processed to make it extremely porous (contains lots of empty space). This means it has a large surface area to allow adsorbtion which is the adhesion of molecules to its surface. Activated carbons ability as an adsorber makes it great for use in filters for treating air and water.

Activated Carbon is great for dechlorination and removing organics, colour and odours from wastewater. It is an important precursor for reverse osmosis (RO) systems to prevent oxidisation.

Powdered Activated Carbon (PAC)

Carbon is crushed or ground into a fine powder. The granules must pass through a certain grade of sieve to be classed as powdered.

Granular Activated Carbon (GAC)

Particles that don’t make it through the sieve are called granular.

Pelletised Activated Carbon or Extruded Activated Carbon (EAC)

A binder is combined with the powdered activated carbon to create a carbon block.

Impregnated Activated Carbon

Some forms of activated carbon are impregnated with inorganic impregnants, such as silver, for use in specific applications.

Acid Washed Activated Carbon

Activated Carbon is acid washed to neutralise its PH level.
