Coagulant Dose Calculator
Audit already-added chemical active mass/water throughput only, no recommended dose, mixing or drinking-water efficacy. Caller independently establishes units, regime, calibration and applicability; this does not establish design-code compliance, authenticity, operational safety, treatment efficacy or a validated forecast.
Description
An observed coagulant concentration combines added active mass with treated water volume.
An observed coagulant concentration combines added active mass with treated water volume.1
It reports supplied treatment data rather than prescribing a dose or proving water quality. Use Coagulant Dose Calculator to evaluate the supplied inputs under the specific model below.
When to use Coagulant Dose Calculator
Use Coagulant Dose Calculator to evaluate the supplied inputs under the specific model below. Establish the units, measurement scope and applicable model or recipe assumptions before entering values.
How to use Coagulant Dose Calculator and understand its results
- Establish the units, measurement scope and applicable model or recipe assumptions before entering values.
- Enter Observed already added coagulant kg, Observed matched treated water m3, Caller verified active mass fractions using the field table and validation rules below, then run the tool.
- Read Observed active coagulant mg l and interpret units, signs, ordering and placeholders as explained below.
- If the tool reports an input error, correct that field and rerun. A successful false result, empty match list or unknown-evidence placeholder has the specific meaning described here; check the limitations before applying the result.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| observedAlreadyAddedCoagulantKg | Observed already added coagulant kg | array of number | Required; constraints below |
| observedMatchedTreatedWaterM3 | Observed matched treated water m3 | array of number | Required; constraints below |
| callerVerifiedActiveMassFractions | Caller verified active mass fractions | array of number | Required; constraints below |
Enter aligned nonempty nonnegative already-added coagulant masses in kg, positive treated volumes in m³ and verified active mass fractions from 0 to 1. Sum active mass and treated volume, then multiply kg/m³ by 1000 to report mg/L. This computes an observed aggregate concentration rather than selecting a treatment dose.
activeMgL = 1000×Σ(addedKg×activeFraction)/ΣtreatedM3 Field order, units and branch conditions follow the implementation explanation above.
| Output field | Meaning | Value type |
|---|---|---|
| observedActiveCoagulantMgL | Observed active coagulant mg l | number |

}Limitations and assumptions
It reports supplied treatment data rather than prescribing a dose or proving water quality. Apply the exact scope and assumptions described above.
All listed fields require explicit values. Unexpected fields, incorrect types, nonfinite numbers and sparse arrays fail validation. Domain-specific bounds, alignments and supported tokens are stated above; extremely large inputs or outputs can also be rejected. These errors differ from successful results such as false, no matches or unknown evidence.
