Like Hans and Franz from the classic Saturday Night Live skit, we’re ready to “Pump you up!” with training and exercises to conquer operator certification exams. Your trainer, wastewater consultant Dan Theobald (“Wastewater Dan”), presents his latest round of Math Solutions.
Many operators are held back from advancing their operating license because they struggle with the mathematics portion of wastewater operator certification examinations. This tool for operators — or educators, engineers, regulators, etc. — offers mathematical templates for performing accurate wastewater calculations in easy-to-follow video tutorials, while also providing definitions, explanations, and alternative applications for the calculations beyond the specific examples presented. What follows are solutions for calculating pumping volumes; they may be applied or adapted to suit your specific plant needs. Actual pumping calculations may have different requirements such as expressing the results as square feet, cubic feet, increment of millions, or even incorporating a time element in calculation solutions.
Pumping Volumes Per Stroke Calculations
Cubic feet pumped per stroke:
Gallons pumped per stroke:
Pumping Solids (Dry Solids And Volatile Solids) Calculations
Pounds of dry solids pumped:
Pounds of volatile solids pumped:
This is the ‘Pumping Calculations’ presentation in my series of “Math Solutions.” If you have specific wastewater math queries, please submit a question.
