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.
