Abstract
Livestock sludge contains high concentration of organic matter and some heavy metals. In case of discharging into the sea, it might have negative effects in the environment. In this study thermal hydrolysis reaction was applied for livestock sludge to determine the fuelization possibility and obtain the best operation conditions. Livestock sludges were thermally hydrolyzed at temperature range $170{\sim}210^{\circ}C$ in sealed high-temperature reactors. Liquid products and dewatered cakes were analyzed. The operation at $190^{\circ}C$ was found to be best effective condition. High heating value and low heating value were 5,050 kcal/kg and 4,740 kcal/kg, respectively. Therefore, fuelization of livestock sludge using thermal hydrolysis reactor is found to be highly effective.
