Description :

Presents and explains the theory of sludge treatment covers us and european disposal regulations and practices intended for advanced students and practitioners of wastewater engineering this text offers the theory and quantitative rationale for treating wastewater and industrial sludges with public safety and efficiency in mind. Sludge disposal is part of what wastewater professionals do but public opinion demands that sludge be treated to higher and higher levels driving sludge treatment technology ever higher as well this book is an excellent source of current. Intended for advanced students and practitioners of wastewater engineering this comprehensive text clearly explains the theory and quantitative rationale for treating wastewater and industrial sludges with public safety and efficiency in mind. Wastewater treatment is a concentration process in which waterborne contaminants are removed from the larger wastewater stream and concentrated in a smaller side stream of slurry called sludge the side stream is too large to be disposed of directly so further concentration processes are required. Sludge digestion is a biological process in which the organic matter present in the sludge is decomposed by micro organisms and is thus stabilized it is accomplished in sludge digestion tanks or digesters which are usually closed cylindrical tanks
