Opis

Written by three leading aeration experts, this book presents the stat e of the art in aeration, using examples from a variety of facilities in the USA and Europe. The authors investigate conventional and deep-t ank aeration systems for BOD removal and nitrification, high-purity ox ygen systems, operating and capital costs, and energy use data. They p resent design information on the adaptation of new aeration technologi es to plants of diverse size. With the information in this book engine ers and managers will be able to understand and monitor the efficiency of existing aeration systems and develop strategies for process impro vement.
