The need for improved water quality means that this treatment is booming. 2. This is typically accomplished by directing the water flow through pressure vessels containing the filter media at a rate that allows enough contact time for adsorption to occur. Drinking water plants have two main choices for change-outs: purchase virgin or unused carbon or use reactivated carbon. Concentration in aqueous phase. ADSORPTION Adsorption is the process in which matter is extracted from one phase and concentrated at the surface of a second phase. Adsorption removes disinfectant chlorine that is often used in municipal water treatment. At the same time, these future water treatment systems will aim to achieve optimum efficiency in terms of operating cost and especially wastewater produced. Wastewater treatment is becoming ever more critical due to diminishing water resources, increasing wastewater disposal costs, and stricter discharge regulations that have lowered permissible contaminant levels in waste streams. by adsorption unto granular activated carbon (GAC) in fixed beds is an important industrial wastewater treatment process (Yeh and Thomas, 1995). The solid that is used universally in the treatment of water is activated carbon, although in recent years, various solid materials have been developed that improve the properties of activated carbon in certain applications. Development of shale gas resources also requires significant quantities of water for drilling and plant operations.

Reading: Sparks, Chap 5 (skip 177 - 182) ... Fine particle can be dispersed and flocculate depending of surface charges. The surface of a colloidal particle tends to acquire an electrostatic charge due to the ionization of surface groups and the adsorption of ions from the surrounding solution. For about 100 years, adsorption technology has been used to a broader extent for water treatment, and during this time, it has not lost its relevance. Every kind of carbon has its own adsorption isotherm (see figure 1) and in the water treatment business this isotherm is definite by the function of Freundlich.
