The selection of sludge handling and disposal methods should include the following considerations (See Chapteralso). thickening and dewatering; This report describes various methods of sludge treatment and disposal: it is intended for those charged with the task of determining the fate of sludge, providing them with the information necessary to select among action alternatives According to the sludge with different water content, this paper recommends four sludge treatment and disposal paths that can reduce GHG emissions, and provides a reference for the selection of sludge treatment and disposal technologies in the future The book covers in a clear and informative way the sludge characteristics, production, treatment (thickening, dewatering, stabilisation, pathogens removal) and disposal (land application for agricultural purposes, sanitary landfills, landfarming and other methods) Municipal This report describes various methods of sludge treatment and disposal: it is intended for those charged with the task of determining the fate of sludge, providing them with the information necessary to select among action alternatives Sludge production is an inevitable outcome of potable water treatment and hence sustainable reuse techniques and disposal methods need to be introduced as a policy for protecting theThe methods used are typically applied to digested sludge and range from drying beds to mechanical dewatering devices, such as filter presses, belt presses and centrifuges. The solids content of the dewatered sludge can range from% to%, depe nding on the type of sludge and the dewatering method adopted Process Selection. In addition to Chapter, only items with a apply to drinking water sludge treatment: Energy requirements; Cost efficiency of sludge. Additionally, using the sludge as an energy sources for future plans was studied as well. Given that sludge disposal to surface waters and the sea is no longer an acceptable method of sludge elimination, landfilling under proper conditions to ensure prevention of air, soil and water pollution is a possible elimination practise not entailing excessive costs The research presented an overview on sludge types, characteristics and methods of treatment. The paper This article provides a brief overview of current methods for the treatment and disposal of sewage sludge, such as soil application, landfill, incineration and anaerobic digestion.
