HOW THIS VERIFICATION WORKS

  1. Step 1: Compute actual surface overflow rate — performs a deterministic calculation from the provided inputs. No acceptance criterion is applied; the result is CALCULATED only.
  2. Step 2: Verify SOR_actual ≤ SOR_design — compares engineering inputs against deterministic thresholds and produces a PASS or FAIL decision.
  3. Step 3: Compute motor full-load torque from nameplate data — performs a deterministic calculation from the provided inputs. No acceptance criterion is applied; the result is CALCULATED only.
  4. Step 4: Compute torque utilization ratio — performs a deterministic calculation from the provided inputs. No acceptance criterion is applied; the result is CALCULATED only.
  5. Step 5: Verify T_util ≤ 0.85 — compares engineering inputs against deterministic thresholds and produces a PASS or FAIL decision.
  6. Step 6: Compute coagulant dose adjustment using jar test calibration — performs a deterministic calculation from the provided inputs. No acceptance criterion is applied; the result is CALCULATED only.
  7. Step 7: Compute weir loading rate — performs a deterministic calculation from the provided inputs. No acceptance criterion is applied; the result is CALCULATED only.
  8. Step 8: Verify WLR_actual ≤ 250 m³/m·d — compares engineering inputs against deterministic thresholds and produces a PASS or FAIL decision.

This tool coordinates 3 validation steps and 5 calculation steps. The overall engineering decision uses ALL_REQUIRED_VALIDATION_PASS aggregation: only validation steps contribute to the pass/fail outcome; calculation steps produce data only.

UNDERSTANDING THE RESULTS

PASS
A proven validation criterion passed. The engineering input satisfies the deterministic threshold.
FAIL
A proven validation criterion failed. The engineering input does not satisfy the deterministic threshold.
CALCULATED
A deterministic calculation completed, but no acceptance criterion exists for this step. CALCULATED does NOT mean PASS.
RESULT NOT VALID
Runtime executed but engineering validity requirements were not met.
INCOMPLETE
Required inputs or workflow steps are incomplete.

The overall decision reflects only validation steps. Calculation steps produce numerical results without pass/fail claims.
