pH Adjustment Chemical Cost at 110% dose utilization share: a worked example

What does the result look like when dose utilization share reaches 110%? The full calculation is worked below with real intermediate numbers. an environmental or operations manager needs to budget or compare ph adjustment chemical cost

The inputs for this scenario

  • Acid or caustic used: 340 gal (unchanged)
  • Chemical cost: 9.6 $ / gal (unchanged)
  • Dose utilization share: 110 % (raised for this scenario; the documented default is 100)
  • Tank, delivery, and testing fees: 420 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Variable cost = acid or caustic used × chemical cost × dose utilization share) to the inputs above produces each figure below.
  • At this operating point the engine returns 4,010 $ for total ph adjustment chemical cost, the number this scenario is built around.
  • At this operating point the engine returns 11.8 $ / gal for ph adjustment chemical cost per gallon.
  • At this operating point the engine returns 3,590 $ for variable ph adjustment chemical cost.
  • At this operating point the engine returns 420 $ for tank, delivery, and testing fees.

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 8.86% above the baseline at 4,010 $.
  • A figure at this level is achievable when dose utilization share is genuinely sustained, not just peaked for a shift. It uses a single blended chemical price and one utilization share, so mixing acid and caustic at different prices, or strength changes between batches, needs separate runs.

Results at a glance

  • Total pH adjustment chemical cost: 4,010 $ (headline result)
  • pH adjustment chemical cost per gallon: 11.8 $ / gal
  • Variable pH adjustment chemical cost: 3,590 $
  • Tank, delivery, and testing fees: 420 $
