A comprehensive guide to understanding the biology and biological conditions of the treatment process

Due to the importance of anaerobic digesters in wastewater treatment processes, a review of the microbiology of the bacteria and the operational conditions that affect their activity are of value in addressing successful and cost–effective operation.

The Microbiology of Anaerobic Digesters the third book in the Wastewater Microbiology Series provides an in–depth review of the bacteria, their activity, and the operational conditions that affect anaerobic digester performance. Avoiding the technical jargon, chemical equations, and kinetics that typically accompany such texts, this comprehensive resource also discusses troubleshooting and process control measures that will allow you to maintain treatment efficiency, prevent system upsets, and reduce operational costs.

Prepared for an audience of operators and technicians who are responsible for the daily operation of anaerobic digesters, The Microbiology of Anaerobic Digesters covers important issues in this field, including:

  • Substrates, products, and biogas
  • Operational conditions, including nutrients, temperature, and alkalinity
  • Process controls and troubleshooting
  • Types of digesters

Fixed film anaerobic digesters are becoming more and more common in the treatment of soluble organic compounds in wastewater. The Microbiology of Anaerobic Digesters will introduce readers to this important topic and provide them with the necessary information for understanding biological conditions of this treatment process.
