Water Treatment Operations Made Easy

A Practical Guide for Licensure

Frank R. Spellman and Joan Price-Bayer

978-1-60595-509-4, March 2019, 472 pages, 6×9, SC Book

  • Key information for water treatment operator certification and licensure
  • Relevant data and questions for passing tests in all US states
  • Explanations of basic math and chemistry in terms of what operators do on a daily basis
  • Step-by-step coverage of unit operations
  • Reviews important material on water sources, watersheds, EPA regulations, contaminant removal, safety, and more

This book starts by laying out the dozens of specific tasks that waterworks operators must know, both to do their job and to achieve certification. After a review of basic math, the volume explains the fundamentals of how water is pumped, stored, and treated and provides the formulas and calculations for monitoring and controlling water flow in multiple plant operations. The book goes into the practical execution of every unit operation in water treatment from intake to distribution, including: screening, mixing, coagulation/flocculation, sedimentation, biosolids removal, filtration, disinfection, and distribution. At every stage, special attention is paid to chemical and other data that operators require to carry out processes and testing, as well as maintain infrastructure. In addition to dozens of worked problems, each chapter includes a review test containing questions similar to those on licensure exams.

In one down-to-earth and clearly written source, this book gives readers the vocabulary, the math, the applied chemistry, and the operational know-how to deliver clean, safe water for distribution–and at the same time to advance in his or her career.
