| Summary: | This paper gives results of a study of biofuel granules made from a waste activated sludge of wastewater treatment. A novel method to enhance waste activated sludge dewaterability with untreated and calcined water treatment sludge of thermal power plants is proposed, and the potential reuse of dewatered sludge as biofuel is evaluated. The water treatment sludge destroyed membrane, resulting in the release of intracellular water by converting bound water into free water, thus enhancing sludge dewaterability. Biofuel granules can be used for technological needs, electricity generation and in heating and hot water supply systems at industrial and domestic facilities. Biofuel granule is a renewable energy that can substituted low grade coal from biomass sources.
