Environmental Engineering: Water, Wastewater, Soil and Groundwater Treatment and Remediation / Edition 6

by Nelson L. Nemerow, Franklin J. Agardy, Patrick J. Sullivan, Joseph A. Salvato

Overview

First published in 1958, Salvato's Environmental Engineering has long been the definitive reference for generations of sanitation and environmental engineers. Approaching its fiftieth year of continual publication in a rapidly changing field, the Sixth Edition has been fully reworked and reorganized into three separate, succinct volumes to adapt to a more complex and scientifically demanding field with dozens of specializations.

Updated and reviewed by leading experts in the field, this revised edition offers new process and plant design examples and added coverage of such subjects as urban and rural systems. Stressing the practicality and appropriateness of treatment, the Sixth Edition provides realistic solutions for the practicing public health official, water treatment engineer, plant operator, and others in the domestic and industrial waste treatment professions.

This volume, Environmental Engineering: Water, Wastewater, Soil and Groundwater Treatment and Remediation, Sixth Edition, covers:

• Water treatment

• Water supply

• Wastewater treatment
