Waste water engineering, written by Dr. B. C. Punmia, Ashok Kumar Jain and Arun Kumar Jain, is a book meant for the students of environmental and Civil Engineering. The book covers the processes involved in the treatment of Sewage water. It deals with the collection and management of Sewage water, the flow of the Sewage water and the construction of canals. It also mentions the design of the sewers and the different sewer pumps. Further, aspects of sewer pumping and waste water discharge using natural means and the different components of a water treatment plant are mentioned in the book. In addition, this book covers the process of treatment involved in waste water, such as sedimentation and Chemical cleaning. The book also discloses the biological treatments involved, including filtering and activated Sludge processing of Sewage. It gives an insight into the advanced and industrial techniques in waste water management. Waste water engineering also has a separate br>Chapter for drainage systems in houses and rural sanitation. Solid waste management and air pollution are also discussed in this book. Dr. B.C. Punmia is a veteran in the field of Civil Engineering and also a ph.Br>d he served at the M.B.M. Engineering college as the hod, Civil Engineering. Ashok Kumar Jain has tremendous expertise in Civil Engineering. He works as a design and field engineer. Arun Kumar Jain is an Assistant Professor of Civil Engineering at the M.B.M. Engineering college. Together, the authors have written many books, including building construction and limit state design of reinforced concrete.
