Preface The Environmental Engineering 2 ECE 602 syllabus of UPTU covers Water Quality Parameters, Water Treatment Process and Wastewater Treatment Process. As such the whole syllabus of this subject was not found in any text book or reference books referred by UPTU syllabus. The key books generally found in market do not have comprehensive explanation of any topic nor their aim is to explain any subject in depth. Teaching this subject many times and realizing the ordeals faced by students and teachers, there was an enormous desire to write a complete book on Environmental Engineering 2 that follows the UPTU syllabus strictly and has detailed explanation of each topic. The emerging technologies in wastewater treatment like duckweed ponds, vermiculture and root zone technologies in Unit 5, is well explained with design examples. The book has Standard Laboratory Manuals with questions asked in viva-voce exams. The book also has solved UPTU questions that have been asked during last six years. The book has solved questions of GATE, asked in last 10 years. The author has had performed a research project on wastewater treatment using ROVSEP Membrane technology in Gotenburg, Sweden in 2005. He has good knowledge and experience in wastewater treatment technologies and has great interest in this area. With these assets he has made an effort to write a book for B.Tech. or M.Tech students of Civil, Mechanical and Chemical Engineering students and all students and teachers who study this subject.
Acknowledgement The author is thankful to Almighty and Omniscient Allah SWT for showering his countless blessings on him and Prophet Muhammad SAW for guiding the whole mankind the best manners of life and for being a mercy upon the whole humanity. The author wishes to express his deep acknowledgement to his mother and father, especially his most respectable father Mr. S. U.

My sisters and brother in laws Mr. Siraj and Mr. Riaz, my brother Yusuf, my wife and my little daughters Aysha and Asma, who provided an ideal book-writing atmosphere at home throughout this venture. The students whom I have taught at various institutes and for whose sake I have learnt the subject over the years are the contributors in absentia. The author acknowledges the general help received from his colleagues like Honourable Director of GCET Dr. R. Sunderasan, Prof. Nuruzzaman, Dr. Shahiq Khan, Jibran Qadri, Javed and Fahim Kirmani. The author wishes to express his gratitude to Vayu Education of India for their enormous contribution in the write-up of this book. The publishers Dr. R.K. Jain and Dr Mrs Usha Rani Jain have taken keen interest in the publication. My efforts would be rewarded if the students and teachers of engineering accept this text and send their comments for further improvements.
