A study of the physical properties and the applications of K-activated carbon system after carbon bed filtration was performed on the bench scale. Various types of K-activated carbon bed were used in this study to investigate the removal efficiency of pollutants from wastewater. From the surface properties obtained for carbon samples treated with aqueous solutions containing metallic K ions, our main investigations involved determining the isotherm shape, pore size distribution, SEM, EDX and surface functional groups. K-Activated carbons were filtrated to wastewater to investigate the removal efficiency for the COD, T-N, and T-P. From the removal results of piggery waste using the K-activated carbon bed, a satisfactory removal performance was achieved. The excellent effects of the K-activated carbon bed were proved by the above-mentioned properties of the material, by the adsorption and trapping of organics, and by its catalytic effects.

Keywords:adsorption;K-activated carbon;isotherm;SEM;EDX
