The Role of Bulking Agent in Pile Methane and Carbon Dioxide Concentration During Wastewater Sludge Windrow Composting

The variation of carbon dioxide (CO sub(2)) and methane (CH sub(4)) concentration in different areas of the pile during wastewater sludge windrow composting was investigated. Pearson correlation was used to examine the correlation of the mean gas concentration in the core with volatile solids and vo...

Description
Summary:The variation of carbon dioxide (CO sub(2)) and methane (CH sub(4)) concentration in different areas of the pile during wastewater sludge windrow composting was investigated. Pearson correlation was used to examine the correlation of the mean gas concentration in the core with volatile solids and volatile solids reduction in each pile. The highest values for both gases and piles were recorded in the core followed by the top. At the side sampling point, the concentrations for both piles and gases were smaller, although statistically significant differences were only measured for CO sub(2). The different bulking agent ratios had no significant effect on the concentration of the two gases in the two piles.
