Wastewater treatment is a microbiological process. Microorganisms, such as bacteria and protozoa, do the actual breakdown and removal of nutrients and organic material in wastewater. A wastewater treatment plant operator’s job is to control this biological process. That is why wastewater operators need to understand basic microbiology as well as the types of microorganisms that are used in the treatment of sewage and how the microbes do their job in the wastewater treatment process. Chapters cover wastewater treatment, general microscopy, bacteria, protozoa, metazoans, filamentous bacteria, microbiology, and process control. Includes a glossary of terms and color photographs of microorganisms on a CD-ROM.
