AWWA Publishes Wastewater Operator Study Guide
This new study guide, which costs $53 for AWWA members and $80 for nonmembers, provides questions similar in content and format to questions that appear on state wastewater-operator certification exams for Grades I, II, III, and IV.
Answers and references are included for further study. Math questions include answers and methods of solution.
The guide provides separate questions and answers for Grades I, II, III, and IV exams, allowing students to focus on their specific grade level. Also included are a special section on pumping and a section on math with 75 math questions and answers (with methods to solve) for conversions, percentages, weights, loading and pumping rates, and dosages.
The study guide includes a Summary of Wastewater Treatment Equations featuring more than 200 equations. These cover area, electricity, biochemical oxygen demand, biosolids pumping, chemical feed rates, dewatering, composting, flow rates, mixtures, dissolved air flotation, and pumping rates.
