Biological Nutrient Removal (BNR) Operation in Wastewater Treatment Plants

Overview

BNR is a fast-growing method of removing biological pollutants (bacteria, etc.) from wastewater. Experts from both the Water Environment Federation and the American Society of Civil Engineers have collaborated on this definitive work which is intended to be a practical manual for plant managers and operators who needed current information on BNR.

PRACTICAL GUIDANCE ON BIOLOGICAL NUTRIENT REMOVAL FOR PLANT MANAGERS AND OPERATORS

Written by industry experts for industry professionals, this complete guide to biological nutrient removal (BNR) provides up-to-date information on plant design and operation for managers, operators, consultants, and those training in wastewater engineering.

Biological Nutrient Removal (BNR) in Wastewater Treatment Plants instructs readers in the theory, equipment, and practical techniques needed to optimize BNR in varied environments, from plants larger than 380 000 m3/d (100 mgd) to plants smaller than 380 m3/d (100 000 gpd), anywhere in the world. The most up-to-date and comprehensive guide ever written on achieving higher standards of water quality through biological nutrient removal, this expert-authored text links practical BNR to all phases of wastewater treatment, covering system design, equipment choices, configuring equipment and processes, monitoring, maintenance, and troubleshooting.

For forward-looking wastewater professionals confronting -- or preparing to confront -- more stringent treatment requirements, this manual is an essential tool.
