| ABSTRACT |
|
A study of the treatment of piggery wastes using a multilayered metal-activated carbon system followed by carbon bed filtration was carried out at bench scale. From the physicochemical properties obtained from samples treated with aqueous solutions containing metallic ions such as Ag', Cu" Na K and Mn2+, main inspections are subjected to isotherm shape, pore distribution with micropore, SEM and EDX. Multilayered metal-activated carbons were contacted to waste water to investigate the simultaneous catalytic effect for the COD, BOD, T-N and T-P removal. From these removal results of the piggery waste using multilayered metal-activated carbon bed, satisfactory removal performance was achieved. The high efficiency of the multilayered metal-activated carbon bed was determined by the properties of this material for trapping, catalytic effect and adsorption of organic solid particles. |
