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.

Uganda's capital, Kampala, is undergoing dramatic urban transformations as its new technocratic government seeks to clean and green the city. Waste Worlds tracks the dynamics of development and disposability unfolding amid struggles over who and what belong in the new Kampala. Garbage materializes these struggles. In the densely inhabited social infrastructures in and around the city's waste streams, people, places, and things become disposable but conditions of disposability are also challenged and undone. Drawing on years of ethnographic research, Jacob Doherty illustrates how waste makes worlds, offering the key intervention that disposability is best understood not existentially, as a condition of social exclusion, but infrastructurally, as a form of injurious social inclusion.

Electronic waste, which includes everything from refrigerators to smartphones, is one of the world's fastest growing waste streams. Often these items are simply discarded as new technology becomes available. A huge amount of electronic waste is generated globally and currently only around 20% of it is recycled.
