Wastewater Load with wastewater treatment connected load of 48 kW: a worked example

Suppose wastewater treatment connected load falls to 48 kW. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate wastewater treatment energy cost for enzyme and bio-ingredient production using treatment load, runtime, electricity cost, and effluent volume.

The inputs for this scenario

  • Wastewater treatment connected load: 48 kW (the input this scenario stresses; the baseline uses 95)
  • Treatment runtime for production scope: 18 hr (held at the documented default)
  • Blended electricity cost: 0.12 $ / kWh (held at the documented default)
  • Effluent volume processed: 420 m3 (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Total wastewater load energy cost = wastewater treatment connected load × treatment runtime for production scope × blended electricity cost.
  • Wastewater treatment energy used works out to 864 kWh at these inputs, and this is the headline figure for the scenario.
  • Total wastewater load energy cost works out to 104 $ at these inputs.
  • Wastewater energy cost per m3 works out to 0.25 $ / piece at these inputs.
  • Hourly wastewater treatment energy cost works out to 5.76 $ / hr at these inputs.

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 49.47% below the baseline at 864 kWh.
  • It computes total treatment energy in kWh, the dollar cost of that energy, and the energy cost per cubic meter of effluent processed. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.
