pH Adjustment Chemical Cost at 72% dose utilization share: a worked example

This worked example runs the ph adjustment chemical cost numbers for a tougher week than the baseline: 72% dose utilization share instead of the typical 100%. Estimate ph adjustment chemical cost from acid or caustic used, chemical cost, applicable share, and fixed environmental fees.

The inputs for this scenario

  • Acid or caustic used: 340 gal (held at the documented default)
  • Chemical cost: 9.6 $ / gal (held at the documented default)
  • Dose utilization share: 72 % (the input this scenario stresses; the baseline uses 100)
  • Tank, delivery, and testing fees: 420 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Variable cost = acid or caustic used × chemical cost × dose utilization share.
  • Total pH adjustment chemical cost works out to 2,770 $ at these inputs, and this is the headline figure for the scenario.
  • pH adjustment chemical cost per gallon works out to 8.15 $ / gal at these inputs.
  • Variable pH adjustment chemical cost works out to 2,350 $ at these inputs.
  • Tank, delivery, and testing fees works out to 420 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where dose utilization share sits at 100% and the headline result is 3,684 $, this scenario comes in 24.81% below the baseline at 2,770 $.
  • Use it for monthly chemical budgeting, invoice validation, or to model the savings from tighter pH control before changing dosing setpoints. 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

  • Total pH adjustment chemical cost: 2,770 $ (headline result)
  • pH adjustment chemical cost per gallon: 8.15 $ / gal
  • Variable pH adjustment chemical cost: 2,350 $
  • Tank, delivery, and testing fees: 420 $
