Mathematical calculations can be a challenge for even the most skilled water and wastewater operator. The formulas for chemical dosing, conversion, filtration, pounds, velocity, volume, and other everyday problems vary, of course, but there are a scant number of basic ground rules that can help make sure your math solution is legitimate regardless of the calculation you’re performing.
The helpful hints below are the summary of my 25-plus years experience and the prowess of other masters.
In doing everything to master the competence of you and/or your colleagues, consider using this tool as another source for ultimate proficiency.
