Plumbing Interceptor Oil Separation Efficiency Calculator
Reconcile actual paired oil/water separator concentrations by independently matched water volumes, not mean percentages or BOD-only alias; signed mass increases retained, no discharge-quality approval.
Description
Oil-removal efficiency compares paired inlet and outlet inventories.
Oil-removal efficiency compares paired inlet and outlet inventories. Matched water volumes provide mass weights for the pooled result.1
The returned values include Observed oil removal fractions, Volume weighted oil mass removal fraction. The How section below explains the calculation, input rules and interpretation.
When to use Plumbing Interceptor Oil Separation Efficiency Calculator
Use Plumbing Interceptor Oil Separation Efficiency Calculator when you need to evaluate the supplied records under the calculation and evidence rules below. No treatment causality, discharge-quality approval or automatic sampling correction is supplied.
Prepare measured flows, pressures, temperatures or inventories with consistent units. For catalog tools, use independently verified capacities at the stated operating conditions and supply the explicit design demand.
How to use Plumbing Interceptor Oil Separation Efficiency Calculator and understand its results
- Prepare measured flows, pressures, temperatures or inventories with consistent units. For catalog tools, use independently verified capacities at the stated operating conditions and supply the explicit design demand.
- Enter observedOilInletMgLiter, observedOilOutletMgLiter, matchedWaterVolumesLiters using the field table and calculation rules, then run the tool.
- Read observedOilRemovalFractions, volumeWeightedOilMassRemovalFraction. The explanation below defines the units, signs, ordering and any flags or placeholder values.
- If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.
| Input field | Meaning | Value type; see rules below | Requirement |
|---|---|---|---|
| observedOilInletMgLiter | Observed oil inlet mg liter | list of number | Required |
| observedOilOutletMgLiter | Observed oil outlet mg liter | list of number | Required |
| matchedWaterVolumesLiters | Matched water volumes liters | list of number | Required |
Enter aligned nonempty positive inlet concentrations and water volumes with nonnegative outlet concentrations. Return batch and pooled removal fractions, retaining negative values if outlet mass increases.
batchRemoval=(inlet−outlet)/inlet; pooled=(sum(inlet×volume)−sum(outlet×volume))/sum(inlet×volume) Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| observedOilRemovalFractions | Observed oil removal fractions | list of number |
| volumeWeightedOilMassRemovalFraction | Volume weighted oil mass removal fraction | number |

}Limitations and assumptions
No treatment causality, discharge-quality approval or automatic sampling correction is supplied.
Numeric inputs, where present, must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Numeric lists are limited to 10,000 entries; string lists to 128 strings of at most 128 characters each. The rules above may impose smaller limits. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.
Alternative or Complementary methods
Use Plumbing Reverse Osmosis Recovery Rate Calculator: Reverse-osmosis recovery compares permeate with feed volume. Volume closure gives concentrate without establishing solute rejection. For a complementary task, use Plumbing Chlorine Contact Time Calculator: Chlorine CT multiplies measured residual concentration by effective contact time. A baffling fraction adjusts nominal volume/flow residence time.
