Daftar Isi:
- The objectives of this research was to evaluate bagasse fly ash ability to reduce the number of H2S, to evaluate the effect of chemical treatment and the effect of size to BFA adsorption ability, to obtain mathematical model that is suitable to describe H2S reducing in tofu waste biogas that occured in fixed bed column, and also to evaluate the adsorption ability from recycle bagasse fly ash. Variable used in this research are bagasse fly ash particle size and bagasse fly ash chemically treatment. Bagasse fly ash particle size are -60+100 mesh and - 200 mesh. Chemically treatment given namely activation using hydrogen peroxide (H2O2) 3%. This treatment is given for bagasse fly ash with particle size -60+100 mesh. The experiment done in fixed bed column and had a continous flow type. Concentration data of effluent and time data obtained are used to evaluate some parameters from Adams Bohart, Thomas, and Yan equation. The suitable model was evaluated using correlation coefficients. The research showed that activated bagasse fly ash had a better ability to reduce H2S level better than non-activated bagasse fly ash. Smaller particle size of bagasse fly ash also had a better ability to adsorp H2S. This research show that Thomas model was the most suitable model to describe the reducing of H2S level in fixed bed column. The best result was obtained by activated bagasse fly ash - 60+100 mesh at flow rate 200 min/minute and initial inlet concentration 154 ppm. The Thomas kinetics constant (kT) and the adsorption capacity (qT) were 0.36 ml/mg/min and 2.42 mg/g and the correlation coefficient obtained was 0.869.
