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.

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

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.

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.

Large volume food processing and preparation operations have increased the need for improved sanitary practices from processing to consumption. This trend presents a challenge to every employee in the food processing and food prepara tion industry. Sanitation is an applied science for the attainment of hygienic conditions. Because of increased emphasis on food safety, sanitation is receiving increased attention from those in the food industry. Traditionally, inexperienced employees with few skills who have received little or no training have been delegated sanitation duties. Yet sanitation employees require intensive training. In the past, these employees, including sanitation program managers, have had only limited access to material on this subject. Technical information has been confined primarily to a limited number of training manuals provided by regulatory agen cies, industry and association manuals, and recommendations from equipment and cleaning compound firms. Most of this material lacks specific information related to the selection of appropriate cleaning methods, equipment, compounds, and sanitizers for maintaining hygienic conditions in food processing and prepara tion facilities. The purpose of this text is to provide sanitation information needed to ensure hygienic practices. Sanitation is a broad subject; thus, principles related to con tamination, cleaning compounds, sanitizers, and cleaning equipment, and specific directions for applying these principles to attain hygienic conditions in food processing and food preparation are discussed. The discussion starts with the importance of sanitation and also includes regulatory requirements and voluntary sanitation programs including additional and updated information on Hazard Analysis Critical Control Points (HACCP).
