| Abstract | In this paper different pre-treatments (involving temperature, pressure and enzymatic processes) were applied to activated sludge from slaughterhouse wastewater treatment with the aim of improving biogas production in anaerobic processes. In order to quantify the efficiency of the above-mentioned pre-treatments, the degree of hydrolysis was evaluated by removal of biodegradability parameters. In addition, the biomethane production and productivity were evaluated by biomethane potential tests. The results showed that all the pre-treated samples obtained higher removal percentages for total chemical oxygen demand, total solids and volatile solids obtaining between 2 and 3.2 times higher values than those without pre-treatments. However, regarding the removal of Total Suspended Solids (TSS) and biomethane yield (Y |
