ABSTRACT

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 typically encounter in the workplace.

Hailed on its first publication as a masterly account written in an engaging, highly readable, user-friendly style, the fully updated Mathematics Manual for Water and Wastewater Treatment Plant Operators: Basic Mathematics for Water and Wastewater Operators introduces and reviews fundamental concepts critical to qualified operators. It builds a strong foundation based on theoretical math concepts, which it then applies to solving practical problems for both water and wastewater operations.

Features:

• Provides a strong foundation based on theoretical math concepts, which it then applies to solving practical problems for both water and wastewater operations.

• Updated throughout and with several new practical problems added.

• Provides illustrative examples for commonly used waterworks and wastewater treatment operations covering unit process operations found in today’s treatment facilities.
