Abstract
The high intracellular water content contained within the cell walls of the bacterial cells of a dewatered biosludge is reduced by removing the intracellular water in a denaturing operation. This operation comprises heating the biosludge at a temperature sufficient to weaken the bacterial cell walls. The weakened cell walls are then exposed to a reduced pressure sufficient to form vapor within the cell and to thus rupture the weakened cell walls and thereby release the intracellular water in the form of a hot aqueous vapor and/or released intracellular water. The water-reduced concentrated biosludge can then serve as a fuel source in a partial oxidation reaction for the production of synthesis gas.
