Adsorption is the accumulation of a gas or liquid on the surface of a liquid or solid substrate, as opposed to absorption, in which the encroaching substance enters the substrate’s bulk or volume.
Activated carbon is porous, inexpensive and readily available for use as adsorbents, furnishing a large surface area to remove contaminants. It has more useful surface area per gram than any other material available for physical adsorption. In fact, a teaspoon of activated carbon has more surface area than a football field.

ACTIVATED CARBON FILTER MEDIA ADSORPTION
Adsorption is a process where a solid is used for removing a soluble substance from the water. In this process active carbon is solid. Activated carbon is produced specifically so as to achieve a very big internal surface. This big internal surface makes active carbon ideal for adsorption. Granular Activated Carbon (GAC) is mostly used in water treatment, it can adsorb the following soluble substances:
- Adsorption of organic, non-polar substances such as:
- Mineral oil
- Poly aromatic hydrocarbons (PACs)
- (Chloride) phenol
- Adsorption of halogenated substance: I, Br, Cl, H en F
- Various fermentation products
- Non-polar substances (Substances which are nonsoluble in water)
EXAMPLES FROM ACTIVE CARBON FILTER MEDIA IN DIFFERENT PROCESSES:
- Groundwater purification
- The de-chlorination of process water
- Water purification for swimming pools
- The polishing of treated effluent
