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 is a special section on pumping, and a section to math with 75 math questions and answers (with methods to solve) for conversions, percentages, weights, loading and pumping rates, dosages, and many other areas covered on certification exams.
The Wastewater Operator Certification Study Guide offers students a handy 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. The guide also makes an excellent on-the-job reference.
