Spellman’s Standard Handbook for Wastewater Operators is a three-volume study guide and readily accessible source of information for review in preparing wastewater personnel for operator certification and licensure. These handbooks are resource manuals and troubleshooting guides that contain a compilation of wastewater treatment information, data, operational material, process control procedures and problem solving, safety and health information, new trends in wastewater treatment administration and technology, and numerous sample problem-solving practice sets, many based on actual tests.The Handbook volumes review the wastewater operator’s job-related knowledge as job requirements identified by the examination developers as essential for a minimally competent Class IV through Class I or Grade I through Grade V wastewater treatment plant operator. Every attempt has been made to make the three Handbook volumes as comprehensive as possible, while maintaining their compact, practical format.
