Primary and activated sludge biogas production: Effect of temperature

Original language description

Sewage sludge management is a problem of growing importance. Anaerobic sewage sludge stabilization is commonly used technology, where organic matter contained in primary and activated sewage sludge is converted into biogas, so both, pollution control and energy recovery can be achieved. The paper deals with the effect of process temperature (36 oC, 42 oC and 50 oC) on biogas production and quality during anaerobic stabilization of primary and activated sewage sludge generated during purifying process in low-loaded activated sludge process. Primary and activated sewage sludge samples were taken at the wastewater treatment plant Brno, Czech Republic. The characteristics of sludges (dry matter and organic dry matter content, pH, conductivity, redox potential) were dermined. Biogas production and quality was measured using 3 anaerobic systems, each of 8 batch anaerobic fermenters, at the 3 different temperature conditions 36 oC, 42 oC and 50 oC. Hydraulic retention time was 20 days. Hypothesis, which predicts that the fermentation of primary and activated sludge provides dissimilar methane quantity and quality under different temperature conditions (36 oC, 42 oC and 50 oC), was partially confirmed. Temperature 42 oC significantly increased biogas production from primary sewage sludge (by 60 % in comparison with production at 36 oC). For activated sewage sludge samples no significant influence of temperature on the biogas production was observed.
