Wastewater Treatment : Concepts And Design Approach

This thoroughly revised Second Edition presents a comprehensive account of the principles of operation and design of wastewater treatment plants.

Beginning with the basic concepts of treatment of wastewater and the design considerations required of an efficient treatment plant, the book moves on to spotlight the design criteria for domestic wastewater treatment units. In essence, the text gives the detailed procedures for design computations of all units of a wastewater treatment plant. It also describes the most common types of reactors used for physical operations and biological processes in wastewater treatment plants.

Besides additional examples and exercises, this edition also includes a new chapter on “Disinfection of Wastewater”.

The book is intended for the undergraduate students of Civil and Environmental Engineering. It will also be useful to the practising professionals involved in the design of wastewater treatment plants.
