Book Description

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: Wastewater Treatment Operations covers all the necessary computations used in wastewater treatment today. It presents math operations that progressively advance to higher, more practical applications, including math operations that operators at the highest level of licensure would be expected to know and perform.


• 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 add several new practical problems.

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