Operator Math, One Topic at a Time

Convert between common units such as MGD, gallons per minute and cubic feet.

Decide whether a wastewater shape calls for area or volume, map its dimensions, and keep feet, square feet, cubic feet, and gallons clear.

Connect idealized basin volume with compatible flow units, handle time units deliberately, and practice solving for time, volume, or flow.

Connect wastewater flow and concentration to pounds per day, then practice rearranging the same relationship to find concentration or flow.

Measure how much liquid moved over an elapsed interval, then find average pumping rate, volume, or time while tracking the units.

Connect water-filled cross-sectional area and velocity to flow, then practice solving the same relationship for velocity or area.

Compare what entered treatment with what remains, then practice solving for percent removal, influent, or effluent concentration.

Connect plant flow and chemical dose to product feed, then practice bounded pump-flow relationships without selecting operating targets.

Use distance and travel time to find how fast water is moving.
