## Basic Math Concepts: For Water and Wastewater Plant Operators (Mathematics for Water and Wastewater Treatment Plant Operato)

### Description:

FROM THE PREFACE

In the years since the first edition, I have continued to consider ways in which the texts could be improved. In this regard, I researched several topics including how people learn (learning styles, etc.), how the brain functions in storing and retrieving information, and the fundamentals of memory systems. Many of the changes incorporated in this second edition are a result of this research. The changes were field-tested during a three-year period in which I taught a water and wastewater mathematics course for Palomar Community College, San Marcos, California.

This first volume, "Basic Math Concepts for Water and Wastewater Plant Operators," provides a thorough review of the necessary mathematical concepts and skills encountered in the daily operations of a water and wastewater treatment plant. Each chapter begins with a skills check to allow the student to determine whether or not a review of the topic is needed. Practice problems illustrate the concepts presented in each section.

## Math for Wastewater Treatment Operators Grades 1 & 2: Practice Problems to Prepare for Wastewater Treatment Operator Certification Exams

### Description:

This new book was written to provide students and operators with examples of a variety of different problems that will be encountered both on the job and for Grades 1 & 2 certification exams. This book is divided into four main parts: a review of significant numbers and rounding; two chapters on math followed by practice tests; and appendices. Each problem is presented with easily followed steps and comments to facilitate understanding. Included after each grade level are tests to help you determine where your strengths or weaknesses are. Appendices contain conversion factors, wastewater treatment equations, chemistry tables, depth-to-diameter tables, and flow charts of wastewater treatment processes.

## Basic Chemistry for Water and Wastewater Operators

### Description:

Water and wastewater operators need an understanding of chemistry to properly carry out the chemical phases of treatment, including coagulation, sedimentation, softening, and disinfection.

Knowledge of basic chemistry is also required to pass operator certification examinations. Operators will get the training they need in this chemistry primer tailored just for operators of drinking water or wastewater systems.

## Mathematics Manual for Water and Wastewater Treatment Plant Operators - Three Volume Set: Mathematics Manual for Water and Wastewater Treatment Plant ... Treatment Plant Operators) (Volume 1)

### Description:

To properly operate a waterworks or wastewater treatment plant and to pass the examination for a waterworks/wastewater operators 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 typically encounter in the workplace.

Hailed on its first publication as a masterly account written in an engaging, highly readable, user-friendly style, the **Mathematics Manual for Water and Wastewater Treatment Plant Operators**, **Second Edition*** *has been expanded and divided into three specialized texts that contain hundreds of worked examples presented in a step-by-step format. They are ideal for all levels of water treatment operators in training and practitioners studying for advanced licensure. In addition, they provide a handy desk reference and handheld guide for daily use in making operational math computations.

This second volume, **Water Treatment Operations: Math Concepts and Calculations**, covers computations commonly used in water treatment with applied math problems specific to waterworks operations, allowing operators of specific unit processes to focus on their area of specialty. It explains calculations for pumping, water source and storage, coagulation and flocculation, sedimentation, filtration, chlorination, fluoridation, and water softening. The text presents math operations that progressively advance to higher, more practical applications of mathematical calculations, including math operations that operators at the highest level of licensure would be expected to know and perform. To ensure correlation to modern practice and design, this volume provides illustrative problems for commonly used waterworks treatment operations found in todays treatment facilities.

## Math Handbook for Wastewater Treatment Plant Operators: Math Fundamentals and Problem Solving

### Description:

**Understandable Step-by-Step Wastewater Math**Wastewater treatment plant operators use mathematics to make key process decisions. It is important for the operator to have an understanding of math fundamentals along with the technical concepts of wastewater treatment plant operation. By reviewing the math principles presented in this text and linking these principles to wastewater treatment processes, the operator can better understand and solve math related problems. This Handbook describes the typical wastewater treatment plant processes encountered by today's operator and shows how to solve process related math problems. The Math Handbook for Wastewater Treatment Plant Operators is also a valuable resource in preparing the operator for math problems given on licensing examinations for wastewater treatment systems. Typical exam problems are solved in an easy to understand, step-by-step format.
