Industrial Wastewater Load with average wastewater flow input of 1.05 MGD: a worked example

What does the result look like when average wastewater flow input reaches 1.05 MGD? The full calculation is worked below with real intermediate numbers. an environmental team needs to understand workload or loading for industrial wastewater load

The inputs for this scenario

  • Average wastewater flow input: 1.05 MGD (raised for this scenario; the documented default is 0.42)
  • Pollutant loading factor: 2,150 lb / MGD-day (unchanged)
  • Sampling or reporting days: 30 days (unchanged)

Working through the calculation

  • Applying the documented formula (Industrial Wastewater Load = average wastewater flow × pollutant loading factor) to the inputs above produces each figure below.
  • At this operating point the engine returns 2,258 lb / day for industrial wastewater load, the number this scenario is built around.
  • At this operating point the engine returns 75.25 lb / day for average pollutant load per reporting day.
  • At this operating point the engine returns 1.05 MGD for average wastewater flow input.
  • At this operating point the engine returns 2,150 lb / MGD-day for pollutant loading factor.

How this compares with the baseline

  • Against the tool's baseline example, where average wastewater flow input sits at 0.42 MGD and the headline result is 903 lb / day, this scenario comes in 150% above the baseline at 2,258 lb / day.
  • A figure at this level is achievable when average wastewater flow input is genuinely sustained, not just peaked for a shift. The loading factor must already reflect the pollutant concentration and the 8.34 conversion; if you only have a concentration in mg/L, convert it to a lb/MGD-day factor first or the result will be wrong.

Results at a glance

  • Industrial Wastewater Load: 2,258 lb / day (headline result)
