Biological and chemical processes play a key role in the treatment of domestic wastewater and are becoming increasingly important in tackling the problems caused by industrial wastes. The first edition of this popular text focused on microbial systems and wastewater processes that are implemented in a treatment plant. While maintaining this approach, this revised edition also incorporates components that cover the fundamental aspects of inorganic and organic chemistry relating to water treatment and pollution.Microbiology and Chemistry for Environmental Scientists and Engineers provides the reader with an understanding of the complex biological and chemical issues involved in environmental science and engineering. A chapter on water quality includes the revised chemical and microbiological standards which will come into force under the new EC drinking water directive. Chemical aspects of water pollution emphasise some of the most dangerous chemical substances prevalent in the environment today.This book will be a valuable addition to the library of practising environmental engineers and scientists, and an essential text for undergraduate and postgraduate students taking courses in environmental, civil and public health engineering.
