Abstract

Dewatered sewage sludge can be liquidized and converted to a free flowing material bytreating between 150 and 200 C under pressure. This thermochemical liquidization phenomenon is due to the rupture of cells of the microorganisms that make up the majo part of sewage sludge, and the water phase is then available to suspend the celluar debri: thus reducing the viscosity. By this technology, organic waste such as dewateret sewage sludge which is solid in form can be easily transformed to liquid materials leading to a variety of technical application such as transport by pipelines, incineration drying, and methanation etc.
