    Up to date and current with the latest technology, Spellman's Standard Handbook for Wastewater Operators: Volume II, Intermediate Level, Second Edition provides a study guide and resource in a compact format. This second of three volumes contains 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.

    New in the Second Edition:

    • Chapter on operator safety
    • Reorganized table of contents
    • Homework problems, examples, and figures

    While the handbook does not discuss the specific content of the examination, it reviews the job-related knowledge identified by the examination developers as essential for minimal competency. More than just a study guide, although it is immediately obvious to readers that the material presented will help them pass licensing exams, the book is designed for practical use and application. Building on the success of the first edition, the second edition contains revised and reorganized information that, if used wisely, helps readers obtain a passing score on certification exams and solve problems on the job.
