  • Patent number: 6673247
    Abstract: A process for dewatering and reducing pathogens in liquid waste sludge having a liquid component and a sludge solids component. Alkaline material is added to the liquid waste sludge. Flocculent may then be mixed with the liquid waste sludge. The liquid waste sludge is then fed into a screw press having a screw. The screw simultaneously heats and dewaters the liquid waste sludge for a sufficient period of time and at a predetermined temperature for the sludge solids component from the screw press to be pasteurized. An apparatus is also provided for carrying out the process for dewatering and reducing pathogens in liquid waste sludge.
