Wastewater Engineering: Design of Water Resource Recovery Facilities (MOP 8 Series) provides the reader with the up-to-date knowledge and tools required to design water resource recovery facilities. It serves as both a textbook for senior level and graduate students in civil engineering and a reference work. The scope of coverage and the classroom-friendly features, such as learning objectives and example problems, makes it an excellent tool for students transitioning from academia to practice, and it remains an essential resource for practitioners. Written by a team of professors and consultants and put through a rigorous industry review, Wastewater Engineering provides vital WRRF design information to an engineer at every stage of their education and career.

This Manual of Practice presents current design considerations for wastewater and stormwater pumping stations. It covers station capacity requirements and configuration, the selection and design of pumping equipment, piping system layout and hydraulic considerations, electrical and instrumentation systems design, and other station appurtenances. Intended for design professionals, it addresses design of stations of all sizes and highlights the differences between wastewater and stormwater stations.

Wastewater Treatment Fundamentals III--Advance Treatment covers all aspects of advanced treatments and helps operators prepare for levels three and four of the operator certification examinations. In addition to learning the basics of advanced treatments operators will gain a thorough understanding of critical aspects of membranes, industrial wastes and pretreatment, chemical treatment, advanced activated sludge, and water reuse. After learning from real-life examples, users can apply the material they learn to situations they encounter in their day-to-day work. Wastewater Treatment Fundamentals III- Advanced Treatment covers: -Robust coverage of Wastewater Treatment Operator exam topics and ABC Need-to-Know Criteria -Peer reviewed -1000+ practice questions to test your knowledge at the end of each chapter -In-depth chapter summaries to reinforce key concepts > This self-study manual aligns with updated Need-to-Know Criteria from the Association of Boards of Certification (ABC) and is based on WEFs extensive existing resource collection, including Operation of Water Resource Recovery Facil

The most comprehensive summary and literature review of Biochemical Oxygen Demand (BOD) on the market! BOD is one of the fundamental concepts in wastewater treatment. Throughout the 1800s and the 1900s, BOD was exhaustively studied and refined, both as a concept and as an analytical procedure. Review all previous BOD work--including why technicians, scientists, plant operators, regulators, and engineers have complained about the BOD test for many years. This book is intended to serve three purposes: first and foremost, is to describe BOD as a test procedure and biological phenomenon; secondly, to describe the place of BOD within the complex of testing that is used to evaluate treatment processes; lastly, is to present the development of BOD and preserve all peer-reviewed literature citations that mark the road to the current test. Chapters detailing sediment oxygen demand, chemical oxygen demand, and total organic carbon testing and their relationship to BOD testing, as well as extensive coverage of the interferences encountered during oxygen demand testing makes this a must-have reference.

This WEF publication serves as a comprehensive summary of water reclamation technologies and practices for minimizing liquid discharge for a broad range of industries. It begins with an overview of factors influencing industry to seek to minimize liquid discharges, followed by a review of alternative technologies, performance expectations, management framework, sustainability tools, and concludes with case studies with input from academia, equipment manufacturers, consultants, and industry. This publication will be of use to practitioners, consultants, management, and R&D professionals who want a timely update on the technologies in use and on those technologies on the horizon to provide the highest rates of water recovery in industrial practice. The industrial sectors covered include the oil and gas sector (unconventional oil and gas, produced and petroleum refining water), pharmaceutical, textile, automotive, manufacturing, energy, and food and beverage. The book covers a much broader perspective than North America, including technology development and sustainable applications within the water scarce yet growing regions of Central and South America, Asia, and the Middle East.

"Wastewater Treatment Fundamentals II--Solids Handling and Support Systems covers all aspects of solids handling and support systems and helps operators prepare for the first three levels of certification examinations. In addition to learning the basics of solids handling, operators will gain a thorough understanding of critical aspects of thickening, dewatering, aeration systems and aerobic digesting. After learning from real-life examples, users can apply the material they learn to situations they encounter in their day-to-day work."--

This publication is intended for use by professionals engaged in the design, approval, and operation of municipal solids treatment and disposal systems. This publication's 26 chapters include contemporary new material on planning, public outreach and involvement, solids production and characterization, design approach, conveyance, conditioning, thickening, waste minimization, anaerobic and aerobic digestion, dewatering, composting, alkaline treatment, disinfection and stabilization, thermal drying, thermal oxidation, pyrolysis and gasification, transport and storage, odor management, sidestreams, instrumentation and monitoring, land application and product distribution, landfill management, emerging technologies, and treatment and utilization of green gases.

The more than 800 study questions and answers in this study companion represent all aspects of liquid treatment processes and help operators prepare for the first three levels of certification examinations. Practicing these questions will allow operators to practically measure and improve their knowledge of the basics of liquid treatment as well as critical aspects of biological treatment, nutrient removal, and disinfection. These questions are also included as "Test Your Knowledge" questions in the Wastewater Treatment Fundamentals I--Liquid Treatment training manual and online course developed in collaboration with the Association of Boards of Certification (ABC). This separate study guide is intended for those operators who do not have the opportunity to use the training manual or online course for study. The peer-reviewed resources in the Wastewater Treatment Fundamentals series represent the expertise of hundreds of water quality professionals. They align with updated Need-to-Know Criteria from the Association of Boards of Certification and are based on WEF's extensive existing resource collection, including Operation of Water Resource Recovery Facilities, MOP 11.

Odor Emissions and Control for Collection Systems and Water Resource Recovery Facilities, 2nd edition, is intended to be the primary reference document for current standards of practice for professionals involved in odor control at wastewater treatment facilities and collections systems. This manual covers all aspects of odor control in wastewater conveyance and treatment facilities, including the basics of odor testing and emissions, sensory analysis, local and state regulations, public outreach, and the technologies used to treat odors. Odor testing and control have undergone rapid advancements since the publication of the first edition of the Water Environment Federation's Manual of Practice 25, Control of Odors and Emissions from Wastewater Treatment Plants. The second edition brings an expanding body of knowledge and real-world experiences to the reader, and it embodies the current state of practice in the industry. The entire manual provides a comprehensive look at all aspects of odor control in the industry today. A new feature of this manual not included in the 2004 edition is the chapter entitled "Collection Systems," which addresses ventilation of sewers, air treatment, and chemical treatment. Odor control in water resource recovery facilities (WRRFs) and solids handling facilities are also covered extensively. This manual also presents best available biological, chemical, and physical technologies for controlling odors; information on analyzing, measuring, and sampling odors; and tools for assessing odor impacts in surrounding neighborhoods and communities. In short, this manual teaches the proper aspects of how to be a good neighbor and share clean air around a treatment facility, while still providing indispensable wastewater services to the larger community.
