Wash Water Load with wash-water system load of 6 kW: a worked example

This worked example runs the wash water load numbers for a tougher week than the baseline: wash-water system load of 6 kW instead of the typical 12 kW. Estimate energy or utility cost for wash-water handling in precursor filtration, washing, neutralization, or wastewater treatment.

The inputs for this scenario

  • Wash-water system load: 6 kW (the input this scenario stresses; the baseline uses 12)
  • Wash-water operating hours: 8 hr (held at the documented default)
  • Energy price: 0.12 $ / kWh (held at the documented default)
  • Precursor washed: 1,000 kg precursor (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Wash-water energy cost = wash-water system load × wash-water operating hours × energy price.
  • Wash-water energy cost works out to 5.76 $ at these inputs, and this is the headline figure for the scenario.
  • Wash-water energy used works out to 48 kWh at these inputs.
  • Wash-water energy cost per kg precursor works out to 0.01 $ / piece at these inputs.
  • Hourly wash-water energy cost works out to 0.72 $ / hr at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where wash-water system load sits at 12 kW and the headline result is 11.52 $, this scenario comes in 50% below the baseline at 5.76 $.
  • Use it when costing a wash cycle, comparing wash-circuit efficiency between lines, or allocating utility energy into precursor cost. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Wash-water energy cost: 5.76 $ (headline result)
  • Wash-water energy used: 48 kWh
  • Wash-water energy cost per kg precursor: 0.01 $ / piece
  • Hourly wash-water energy cost: 0.72 $ / hr
