Karlsruhe, Germany: DVWG Forschungsstelle. 2 Chapter 1 Fundamentals of Adsorption Adsorption is used in water treatment to remove dissolved contaminants by physical phase separation in either a steady-state (PAC) or a nonsteady-state (GAC) process. Adsorbates accumulate on the surface of the adsorbent until the adsorption capacity is consumed. In the PAC process, the PAC is removed from the water treatment stream as a process solids residual. In the GAC process, once the effluent concentration of the adsorbate reaches the treatment objective, the GAC must be replaced in order to continue satisfactory performance.

2000) developed a bench-scale protocol for PAC selection and optimization. The protocol uses standard jar test procedures with an emphasis on simulating 19 Activated Carbon: Solutions for Improving Water Quality _______________________________________ full-scale conditions. Figure 2-5 illustrates typical results for two utilities. The procedure takes advantage of initial concentration not affecting the fractional removal. Thus, the utility can run the test at one target compound initial concentration and generalize the removal to other initial concentrations.

The reactivation requires conditions very similar to the activation process used in the original production. During reactivation, some adsorbed compounds are thermally desorbed, but most compounds, including the adsorbed DOM, are oxidized on the GAC surface. The surface chemistry of activated carbon is a product of the raw materials and the activation process. , ash), both of which can negatively affect the adsorption of some compounds. Adsorption Adsorption is the accumulation of a substance (the adsorbate) on the surface of a solid (the adsorbent).
