Modelling inhibitory effects of long chain fatty acids in the anaerobic digesti...
Zonta, Z.; Alves, M. M.; Flotats, X.; Palatsi, J.Mathematical modelling of anaerobic digestion process has been used to give new insights regarding dynamics of the long chain fatty acids (LCFA) inhibition. Previously published experimental data, including batch tests with clay mineral bentonite additions, were used for parameter identification. New kinetics were considered to describe the bio-physics of the inhibitory process, including: i) adsorption of LCFA...
Influence of adsorption and anaerobic granular sludge characteristics on long c...
Palatsi, J.; Affes, R.; Fernandez, B.; Pereira, M. A.; Alves, M. M.; Flotats, X.The impact of LCFA adsorption on the methanogenic activity was evaluated in batch assays for two anaerobic granular sludges in the presence and absence of bentonite as synthetic adsorbent. A clear inhibitory effect at an oleate (C18:1) concentration of 0.5 g(C18:1) L(-1) was observed for both sludges. Palmitate (C16:0) was confirmed to be the main intermediate of C18:1 degradation in not adapted sludge and its ...
