Spellman's Standard Handbook for Wastewater Operators, Volume 2: Intermediate Level provides information and unit process trouble-shooting guidance required on a daily basis, not only by the plant manager, plant superintendent, chief operator, lab technician, maintenance operator, but more importantly by and for the plant operator, and those in preparation for taking the entry-level Class IV/Class III or Grade I/II operator examinations. This handbook was prepared to help operators obtain licensing and to operate wastewater treatment plants properly. It can be used as a textbook in technical training courses in technical schools and at the junior college level.
This is the second volume of a new 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.
