Book Description
Global concern about climate change caused by the exploitation of fossil fuels is encouraging the use of renewable energies. For instance, the European Union aims to be climate neutral by 2050. Biogas is an interesting renewable energy source due to its high calorific value. Today, biogas is mainly used for the production of electricity and heat by a combined heat and power engine. However, before its valorization, biogas needs to be desulfurized (H2S removal) to avoid corrosion and sulfur oxides emissions during its combustion. Biogas can be upgraded (CO2 removal) and used as vehicle fuel or injected into the natural gas grid. In the last 15 years, significant advances have occurred in the development of biological desulfurization processes. In this book with five chapters, the reader can find some of the latest advances in the biogas desulfurization and an overview of the state-of-the-art research. Three of them are research studies and two are reviews concerning the current state of biogas desulfurization technologies, economic analysis of alternatives, and the microbial ecology in biofiltration units. Biogas desulfurization is considered to be essential by many stakeholders (biogas producers, suppliers of biogas upgrading devices, gas traders, researchers, etc.) all around the world.

Book Description
Ponds (lagoons) have been used for centuries with great success in the treatment of wastewater. Ponds created for treatment, known as stabilization ponds, model the physical and biochemical interactions that occur in natural ponds. Easy to build and manage, stabilization ponds can accommodate large fluctuations in flow, and provide results that are

Book Description
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. Eschewing the technical jargon and copious chemical equations found in the majority of wastewater studies, Settleability Problems and Loss of Solids in the Activated Sludge Process speaks directly to plant operators, showing them how to identify and solve common problems and achieve maximum efficiency. Michael H. Gerardi’s hands-on guide addresses the most common plant operational problems, such as increased costs, loss of treatment efficiency, and permit violations. Using numerous tables and illustrations, Settleability Problems provides microscopic and analytical techniques for troubleshooting and identifying the conditions responsible for settleability problems and loss of solids. It includes pictures of wet mounts and smears of acceptable and unacceptable microscopic conditions of the activated sludge and presents corrective measures for operational problems. Chapters include: Undesired Filamentous Growth Nutrient-Deficient Floc Particles Denitrification Slug Discharge of Soluble cBOD Viscous Bulking or Zoogloeal Growth Production and Accumulation of Foam and Scum Volume II in the series, Settleability Problems will prove to be of unparalleled value to wastewater treatment plant operators as well as students of wastewater microbiology.

Book Description
Biological Wastewater Treatment in Warm Climate Regions gives a state-of-the-art presentation of the science and technology of biological wastewater treatment, particularly domestic sewage. The book covers the main treatment processes used worldwide with wastewater treatment in warm climate regions given a particular emphasis where simple, affordable and sustainable solutions are required. This comprehensive book presents in a clear and informative way the basic principles of biological wastewater treatment, including theory and practice, and covering conception, design and operation. In order to ensure the practical and didactic view of the book, 371 illustrations, 322 summary tables and 117 examples are included. All major wastewater treatment processes are covered by full and interlinked design examples which are built up throughout the book, from the determination of wastewater characteristics, the impact of discharge into rivers and lakes, the design of several wastewater treatment processes and the design of sludge treatment and disposal units. The 55 chapters are divided into 7 parts over two volumes: Volume One: (1) Introduction to wastewater characteristics, treatment and disposal; (2) Basic principles of wastewater treatment; (3) Stabilisation ponds; (4) Anaerobic reactors; Volume Two: (5) Activated sludge; (6) Aerobic biofilm reactors; (7) Sludge treatment and disposal. As well as being an ideal textbook, Biological Wastewater Treatment in Warm Climate Regions is an important reference for practising professionals such as engineers, biologists, chemists and environmental scientists, acting in consulting companies, water authorities and environmental agencies.

Book Description
Practical techniques for handling industrial waste and designing treatment facilities Practical Wastewater Treatment is designed as a teaching and training tool for chemical, civil, and environmental engineers. Based on an AIChE training course, developed and taught by the author, this manual equips readers with the skills and knowledge needed to design a wastewater treatment plant and handle various types of industrial wastes. With its emphasis on design issues and practical considerations, the manual enables readers to master treatment techniques for managing a wide range of industrial wastes, including oil, blood and protein, milk, plating, refinery, and phenolic and chemical plant wastes. A key topic presented in the manual is biological modeling for designing wastewater treatment plants. The author demonstrates how these models lead to both more efficient and more economical plants. As a practical training tool, this manual contains a number of features to assist readers in tackling complex, real-world problems, including: * Examples and worked problems throughout the manual demonstrate how various treatment plants and treatment techniques work * Figures and diagrams help readers visualize and understand complex design issues * References as well as links to online resources serve as a gateway to additional information * Practical design hints, stemming from the author's extensive experience, help readers save time and avoid unwanted and expensive pitfalls * Clear and logically organized presentation has been developed and refined based on an AIChE course taught by the author in the United States, Mexico, and Venezuela Whether a novice or experienced practitioner, any engineer who deals with the treatment of industrial waste will find a myriad of practical advice and useful techniques that they can immediately apply to solve problems in wastewater treatment.

Book Description
A practical guide to wastewater bacteria and the roles they perform in wastewater treatment Communicating material in a practical manner for operators and technicians who regulate and troubleshoot their wastewater treatment processes, Wastewater Bacteria discusses the effective control and proper operation of aerobic (activated sludge) and anaerobic (anaerobic digesters) biological treatment units to ensure that an adequate, active, and appropriate population of bacteria is present in each treatment unit. It is a hands-on guide to understanding the biology and biological conditions that occur at each treatment unit. Avoiding unnecessary technical jargon and chemical equations, Wastewater Bacteria, the fifth book in the Wastewater Microbiology Series, explores and explains: * Bacteria and the wastewater environment * Enzymes and sludge production * Nitrogen, phosphorus, and sulfur bacteria * Floc formation and filamentous organisms * Nitrification and denitrification * Sulfate reduction, fermentation, and methane production * Toxicity * Foam and malodor production The goal of Wastewater Bacteria is to enable plant operators to achieve the twofold basic objectives of wastewater treatment-to degrade organic wastes to a level where a significant, dissolved oxygen demand is not exerted upon receiving waters and to remove nutrients to levels where photosynthetic organisms in receiving waters are limited in their growth. This straightforward manual equips plant technicians to meet these objectives with essential information to understand the biological processes and organisms involved in wastewater treatment.
