Hailed on first publication as a straightforward, practical, and to-the-point account of wastewater principles, practices, and operations for general readers, students, and wastewater operators in training and for all levels of operators at any level of licensure, Spellman's Standard Handbook for Wastewater Operators Volumes I, II, and III almost instantly became the standard resource for this field. The second edition continues the tradition, exploring important aspects of wastewater operations and operator preparation for licensure examinations. Each volume has been upgraded, updated, and expanded to include additional pertinent information to better prepare each qualified user for professional licensure. More than just a study guide or readily accessible source of information for preparing wastewater personnel for operator certification and licensure, this three-volume resource manual and troubleshooting guide compiles wastewater treatment information, data, operations material, process control procedures, safety and health information, new trends in wastewater treatment administration and technology, and numerous sample problem-solving practice sets. Drawing on Frank Spellman's expertise and experience, this book provides: Instant access to information that aids in the efficient operation of a wastewater treatment plant Basic information and sample problem sets needed to prepare for state licensing and certification examinations User-friendly, straightforward fundamental reference material organized into three focused volumes Contrary to popular belief, treating wastewater is not just a science, but both an art and a science. It requires technical expertise, experience, and an understanding of a broad range of available technologies. With coverage ranging from pumping and screening influent, treating the waste stream, through managing biosolids, this three-volume set provides easy-to-understand state-of-the-art information in an accessible format. Though formatted at three separate levels, overlap between each volume not only ensures continuity and a smooth read form volume to volume, but makes each one a handheld, stand-alone reference that presents essential information in a precise, efficient, and effective manner.
