Desalination & Membrane Water Treatment Equipment worked example

Compliance Monitoring Energy Load with monitoring equipment connected load of 30 kW: a worked example

Push monitoring equipment connected load up to 30 kW and the picture changes. This example computes every intermediate figure at that operating point. Use it when compliance monitoring energy load in desalination and membrane water treatment equipment is up for an upgrade and you want a defensible savings story.

The inputs for this scenario

  • Monitoring equipment connected load: 30 kW (raised for this scenario; the documented default is 12)
  • Compliance monitoring runtime: 8 hr (unchanged)
  • Blended electricity rate: 0.12 $ / kWh (unchanged)
  • Treated volume or samples covered: 1,000 m³ or samples (unchanged)

Working through the calculation

  • Applying the documented formula (Total compliance monitoring energy cost = monitoring equipment connected load × compliance monitoring runtime × blended electricity rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 240 kWh for compliance monitoring energy used, the number this scenario is built around.
  • At this operating point the engine returns 28.8 $ for total compliance monitoring energy cost.
  • At this operating point the engine returns 0.03 $ / piece for compliance energy cost per volume or sample.
  • At this operating point the engine returns 3.6 $ / hr for hourly compliance monitoring energy cost.

How this compares with the baseline

  • Against the tool's baseline example, where monitoring equipment connected load sits at 12 kW and the headline result is 96 kWh, this scenario comes in 150% above the baseline at 240 kWh.
  • It multiplies the monitoring equipment's connected load by its runtime to get energy used, applies the electricity rate for total cost, and divides by treated volume or samples for a unit cost. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.
