Opis

Retaining the same successful and proven format used in the bestselling first edition, Spellman s Standard Handbook for Wastewater Operators: Volume I, Fundamental Level, Second Edition contains the necessary information to successfully study for and pass currently administered certification examinations. Primarily designed to provide a readily accessible, user-friendly source of information for review in preparing for the first levels of licensure, this volume also sets the stage for Volumes II and III.

Revised and expanded with additional information and example problems, changes to this volume include:

• A new chapter on basic microbiology
• More than double the amount of water hydraulics and pumping information
• More operational computation problems and examples in all major topic areas

The book provides review questions and answers as well as a comprehensive practice examination for measuring the level of knowledge attained through study, on the job experience, and other sources. By using the final examination as a measuring stick, readers can determine strong and weak points. Appendix C contains a formula sheet to be used for reference when taking the final examination. Constructed in a way that allows readers to build their knowledge base, step by step, page by page, as they progress through the material, the handbook represents a basic summary of expert information and includes references to many other sources.

Also available as a volume in Spellman's Standard Handbook for Wastewater Operators, Second Edition (3 Volume Set)
