ABSTRACT

When studying a discipline that does not include mathematics, one thing is certain: the discipline under study has nothing or little to do with science. (Spellman, The Science of Air, 1999)

3.1 IN TR O D U C TIO N

An y o n e who has had the opportunity to work in wastewater treatment, for even a short time, quickly learns that wastewater treatment operations involve a large number of process control calculations. All of these calculations are based upon basic math principles. In this chapter, we cover basic mathematical operations that wastewater operators are required to use, many of them on a daily basis. Along with an explanation of each math operation, several sample problems are included. A practice test is included at the end of this chapter to determine your level of math skill-this is important because, without mastering basic math skills, the user of this text will find subsequent chapters (which include a lot of math) difficult to complete.
