A comprehensive, self-contained mathematics reference, The Mathematics Manual for Water and Wastewater Treatment Plant Operators will be useful to operators of all levels of expertise and experience. The text is divided into three parts. Part 1 covers basic math, Part 2 covers applied math concepts, and Part 3 presents a comprehensive workbook with

To properly operate a waterworks or wastewater treatment plant and to pass the examination for a waterworks/wastewater operator's license, it is necessary to know how to perform certain calculations. All operators, at all levels of licensure, need a basic understanding of arithmetic and problem-solving techniques to solve the problems they typicall

This book is for newer wastewater treatment operators who are studying for the Grade 2 exam (second certification level from the bottom). It contains 360 questions that help operators prepare for the wastewater treatment operator certification exam. There are 4 full-length practice exams in this book. Each test consists of 90 questions that cover wastewater treatment concepts and relevant math problems. The first two exams are all multiple choice, while the last two exams contain both true/false and multiple choice questions. Topics covered: Preliminary Treatment, Screening, Grit Channel, Primary Treatment, Primary Sedimentation, Secondary Treatment, Trickling Filters, Activated Sludge, RBC, Secondary Sedimentation, Waste Stabilization Ponds, Disinfection, Sludge Handling, Anaerobic Digestion, Safety, Sampling, Pumps, Laboratory Work, Analysis of Wastewater Constituents, and Basic Supervision Responsibilities. Math Section: Hydraulic Loading, Organic Loading, SVI, Removal Efficiency, F/M Ratio, MCRT, Pumping Rate, Percent Volatile Solids Reduction, Flowrate of Primary Sludge, Detention Time, Chlorine Residual and Demand, Weir Overflow Rate, Sludge Age, Surface Loading Rate, Solids Loading Rate, and Population Loading.
