In this paper, the effectiveness of granular activated carbon made from agricultural waste (sawdust) for the removal of Total Dissolved Solid Particles (TDSP) in wastewater from a brewery industry was investigated. The adsorbent activation capacity was enhanced by treating it with acid. Batch mode experiments were conducted to study the effects of contact time, pH, temperature, and adsorbent dosages on TDSP adsorption. Equilibrium adsorption isotherms, kinetics and sorption mechanism were investigated from the results generated from batch experiment. The experimental data were analyzed by Langmuir, Freundlich, and Temkin models and the isotherm data fitted well to the Langmuir isotherm, with monolayer adsorption capacity of 8.40mg/g. The kinetic data obtained at different dosages were analyzed using Pseudo-first order, Pseudo-second order and the sorption mechanism was also analyzed using Intraparticle diffusion model. The experimental data fitted very well the Pseudo-second order kinetic model. The intraparticle diffusion analysis obtained shows the adsorption process as one of the rate determining steps. The sawdust activated carbon in acid (SACA) was found to be effective and economically viable adsorbent for TDSP adsorption.
