Waste-Water Engineering

Importance of water to the existence of human life is next to air. Human settlements, towns and cities are dependent upon the continuous supply of water from different sources. Water exists in all the three forms??"solid, liquid and gas??"and all the three forms are important to humans as well as all the biological systems. This edition discusses importance, properties and uses of water, along with quality, sources and classification. Conveyance of water, quality, and waste-water treatment are the topics focussed upon. Besides filtration, both physical and chemical operations have been discussed thoroughly. Water transmission and distribution systems have been discussed. Biological waste treatment, residual management, treatment of sewage, along with systems for resource and energy and connected microbiology have been described. Separate chapters have been included to cover hydraulics and use of computers in waste-water technology. Appendices and glossary at the end of the text provide a quick reference to the readers. This book is a complete treatise on water processing techniques including recycling and reuse of waste-water, making it an essential reading for all students and teachers of graduate and postgraduate courses in engineering, environment, life sciences, water technology and concerned industrial applications.

Importanta apei pentru existenta vietii umane este alaturi de aer. Asezarile umane, orasele si orasele sunt dependente de furnizarea continua de apa din diferite surse.
