Math Solutions: Real-Life Wastewater Calculations
By Daniel Theobald, "Wastewater Dan"
Water Online’s “Math Solutions” series, presented by wastewater consultant and trainer Dan Theobald (“Wastewater Dan”), instructs operators on wastewater treatment calculations.
The ongoing “Math Solutions” series was designed to prepare operators for certification exams, which themselves are preparation for day-to-day treatment plant operations. But for this segment, Wastewater Dan reverses course and prioritizes “real life” ahead of the classroom, addressing math problems encountered in the field and sent in by readers — though they could appear on exams as well.
When applying the following in real life, converting the unit or time of expression may be required for an accurate calculation.
Calculate pressure (psi) at tank bottom:
Calculate feet of water in tank:
Calculate weight of gallons in tank:
Calculate pounds of chlorine used in one year:
Calculate hours required for pump to run:
