Sludge Management provides up-to-date information on sludge treatment, reuse and disposal. A comprehensive coverage of all issues related to sludge management is included with local through global coverage of all sludge management practices. Conventional to advanced technologies for sludge management with available case studies from both developing and developed countries are covered in this book. Given the responsibility of engineers to develop the technological tools to meet the increasingly stricter standards for sludge treatment and disposal, the main attraction of the book principally relies on its technical content that reviews all the points to be considered in sludge management from engineering and technological perspectives. Sludge Management can be used for planning, designing, and implementing waste sludge management projects. Moreover, this book can be used as a standard textbook in Universities for Master and Doctoral students. Also, academics, researchers, scientists, and practicing engineers working in the field of sludge management would find the book very informative and a source of interesting case studies.
