Introduction to Wastewater Treatment Processes, Second Edition presents the principles of chemical kinetics, reactor design, and the mechanism of biological treatment processes. This book provides the numerical applications that illustrate the treatment of laboratory data. Organized into eight chapters, this edition begins with an overview of the engineering design of process plants for treatment of wastewaters of industrial or domestic origin. This text then examines the various empirical methods for evaluation of concentration of contaminants in wastewaters. Other chapters consider the various types of primary treatment of wastewater, including sedimentation, screening, flotation, and neutralization and equalization. This book discusses as well the stationary film theory applied to the case of oxygen transfer. The final chapter deals with tertiary or advanced wastewater treatment, which consists of processes designed to achieve higher effluent quality than conventional secondary treatment. This book is a valuable resource for practicing engineers and students who are interested in the field of wastewater treatment.
