Description
Return removedLoad = inletLoad-outletLoad, measuredRemovalFraction = removedLoad/inletLoad and residualLoadGap = outletLoad-inletLoad*(1-baselineRemovalFraction).
A pollutant load combines concentration with a compatible flow, volume or activity factor. A load rate has amount-per-time units, whereas an integrated load also includes duration; concentration differences alone do not describe removal when flows differ.
Return removedLoad = inletLoad-outletLoad, measuredRemovalFraction = removedLoad/inletLoad and residualLoadGap = outletLoad-inletLoad*(1-baselineRemovalFraction).
When to use this tool
Use Treatment Load Baseline Gap when checking one supplied emission, transport or treatment mass-balance contribution.
How to use the tool and how it works
- Enter inletLoad, outletLoad, baselineRemovalFraction. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read removedLoad, measuredRemovalFraction, residualLoadGap. Use the output convention below.
Require positive inletLoad, nonnegative outletLoad and baselineRemovalFraction in [0,1]. Return removedLoad = inletLoad-outletLoad, measuredRemovalFraction = removedLoad/inletLoad and residualLoadGap = outletLoad-inletLoad*(1-baselineRemovalFraction).1

}Limitations and assumptions
- Use matching loads and time bases. An outlet above the inlet produces negative removal, while a positive residual gap means more outlet load than the supplied baseline permits; the baseline is not an automatically selected treatment or legal standard.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Integrate changing measurements over time and reconcile storage and reactions when a constant-condition product is insufficient.
