Description
Book SynopsisThis book reviews the significant bacterial groups, the roles they perform in wastewater treatment, and the operational conditions that affect their activity. The roles that are performed by each bacterial group may be beneficial or detrimental to the biological treatment unit depend upon the operational conditions of the unit.
Trade Review"...a hand-on guide to understanding the biology and biological conditions that occur at each treatment unit." (
Journal of the American Water Resources Association, October 2006)
