One sewage sludge (SLA) from A ´vila region (Spain) was selected and used as raw material in order to study the influence of acid treatment on the pyrolysis behavior of sewage sludges. SLA was heat treated with acid solutions at pH 1 and pH 2 leading to SLA-1 and SLA-2, respectively. Characterizatio
Batch digestion experiments were conducted to determine the effects of inoculum:substrate ratio and initial medium pH on methane production from glucose. A ratio between the chemical oxygen demands (COD) of the substrate and inoculum solids (SISR) was used to quantify the food to microorganisms (F/M
