Wastewater Load with wastewater treatment connected load of 240 kW: a worked example

This scenario runs the wastewater load calculation on the strong side: wastewater treatment connected load of 240 kW, with every other input held at its documented default. Use it when fermentation, cleaning, filtration, or drying operations create wastewater treatment demand that should be included in batch or campaign cost.

The inputs for this scenario

  • Wastewater treatment connected load: 240 kW (raised for this scenario; the documented default is 95)
  • Treatment runtime for production scope: 18 hr (unchanged)
  • Blended electricity cost: 0.12 $ / kWh (unchanged)
  • Effluent volume processed: 420 m3 (unchanged)

Working through the calculation

  • Applying the documented formula (Total wastewater load energy cost = wastewater treatment connected load × treatment runtime for production scope × blended electricity cost) to the inputs above produces each figure below.
  • At this operating point the engine returns 4,320 kWh for wastewater treatment energy used, the number this scenario is built around.
  • At this operating point the engine returns 518 $ for total wastewater load energy cost.
  • At this operating point the engine returns 1.23 $ / piece for wastewater energy cost per m3.
  • At this operating point the engine returns 28.8 $ / hr for hourly wastewater treatment energy cost.

How this compares with the baseline

  • Against the tool's baseline example, where wastewater treatment connected load sits at 95 kW and the headline result is 1,710 kWh, this scenario comes in 153% above the baseline at 4,320 kWh.
  • Use it when allocating utility cost to a production batch, evaluating an aeration or VFD upgrade, or benchmarking effluent energy intensity across campaigns or sites. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Wastewater treatment energy used: 4,320 kWh (headline result)
