Adsorbents have been developed to find an economic and efficient way to treat the textile wastewater. Adsorption is mainly used method in physicochemical wastewater treatment, which can merge the wastewater and the porous material powder or granules, such as activated carbon and clay, or allow the wastewater through its filter bed composed of granular materials. Through this process effluents in the wastewater are adsorbed and removed on the surface of the porous material or filter. High efficiency of activated carbon makes adsorption a suitable technique for the removal of pollutants from wastewater. However, the economics of the process utilizing adsorption rely on the regeneration and the re-use of the depleted adsorbent.
