This 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.

An invaluable troubleshooting tool,Microscopic Examination of the Activated Sludge Process addresses how to use the microscope and provides proper techniques for sample preparation. It explains how to relate and interpret observations and whether observing conditions are desirable or undesirable.

For years, operators have been taught that they have very little control over lagoon and fixed film sewage treatment systems. This book gives these personnel a new understanding of how these processes work and does so in a practical manner that emphasizes necessary information for understanding biological conditions at the treatment process.

For years, operators have learned that they have little control over lagoon and fixed film sewage treatment systems.

The activated sludge process is the most versatile, commonly used wastewater treatment system in North America; however, many activated sludge processes frequently experience operational problems related to poor compaction or settleability of secondary solids and loss of secondary solids from the clarifier. This work covers this topic.

This manual provides the reader with a review of the significant pathogenic groups of organisms and specific pathogens of concern within wastewater and sludges. Groups reviewed include viruses, bacteria, fungi, protozoa, and helminthes or worms.

This publication reviews the microbiology of wastewater treatment focusing on the activated sludge process. It addresses critical topics such as cost-effective operation, permit compliance process control and troubleshooting through a microbiological perspective.
