ABSTRACT
Without the ability to perform mathematical calculations, it would be difficult for operators to properly operate water/wastewater treatment systems. As with all math operations, many methods can be successfully used to solve water/wastewater system problems. During the day-to-day operation of a wastewater treatment plant, considerable mathematical data is collected. Most of the calculations made in the water/wastewater operations involve using units. Water and wastewater operators are often required to calculate surface areas and volumes. Area is a calculation of the surface of an object. For example, the length and the width of a water tank can be measured, but the surface area of the water in the tank must be calculated. Force, pressure, and head are important parameters in water and wastewater operations. In water and wastewater treatment, one of the major concerns of the operator is not only to maintain flow but also to measure it.
