Powdered activated carbon. Integration of Activated Carbon Adsorption and Biological Processes in Wastewater Treatment. Adsorption from wastewater onto activated carbon can occur as a result of two separate properties of the wastewater-activated carbon system, or some combination of the two: (1) the low solubility of a particular solute in the wastewater; and (2) a high affinity of a particular solute in the wastewater for the activated carbon. Research is now being directed towards the modification of carbon surfaces to enhance its adsorption potential towards specific pollutants. Today, the most commonly adopted adsorbent is the activated carbon. Activated carbon is an effective adsorbent because it is a highly porous material and provides a large surface area to which contaminants may adsorb. Active carbon adsorption can also be used for the removal of PER from wastewater from the dry cleaning sector.
