Nitrification and Denitrification in the Activated Sludge Process: Wastewater Microbiology

Autor MH Gerardi
en Limba Engleză Paperback – 22 ian 2002
A practical guide to wastewater treatment for plant technicians and operators This book, the first in a series on the microbiology of wastewater treatment, comprises the critical topics of cost-effective operation, permit compliance, process control, and troubleshooting in wastewater treatment plants. Avoiding the technical jargon, chemical equations, and kinetics that typically accompany such texts, Nitrification and Denitrification in the Activated Sludge Process directly addresses plant operators and technicians, providing necessary information for understanding the microbiology and biological conditions that occur in the treatment process.
Of special interest to wastewater treatment plant operators are the bacteria that degrade nitrogenous wastes-the nitrifying bacteria-and the bacteria that degrade carbonaceous wastes-the cBOD-removing bacteria. Both groups of bacteria need to be routinely monitored and operational conditions favorably adjusted to ensure desired nitrification. Each chapter in this groundbreaking study offers a better understanding of the importance of nitrification and denitrification and the bacteria involved in these crucial processes. Chapters include:
  • Organotrophs
  • The Wastewater Nitrogen Cycle
  • Nitrite Ion Accumulation
  • Dissolved Oxygen
  • Denitrifying Bacteria
  • Gaseous End Products
  • Free Molecular Oxygen
  • The Occurrence of Denitrification
Nitrification and Denitrification in the Activated Sludge Process is an ideal companion for operators and technicians of wastewater treatment plants as they study to receive certification in their field, now required in more than thirty states. Sanitary engineers, chemists, microbiologists, and educators will benefit from this comprehensive guide.

1. The proposed series of manuals is targeted for and audience of operators and technicians who are required to daily regulate and troubleshoot their treatment processes. Many operators are required a to obtain state certification or licensing in order to operate their treatment processes. Certification or licensing often requires successful complete of tests and course work. The manuals may b used to prepare operators and technicians for tests. Approximately 30 states require operators to obtain certification and periodically complete wastewater courses. During the years 2000 and 2001 several more states will require operator to complete wastewater courses in order to obtain certification or license. These states include California, Illinois, Michigan, New Jersey, North Carolina, Ohio, and Pennsylvania. The number of operator in each state range from 5,000 to 12,000
2. These titles will also be valuable resource for sanitary engineers, chemists, microbiologists, and educators



Descriere

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.
