HOW THIS VERIFICATION WORKS

Step 1: Compute minimum wash pressure to overcome cake–belt adhesion — performs a deterministic calculation from the provided inputs. No acceptance criterion is applied; the result is CALCULATED only.
Step 2: Calculate mechanical safety margin for scroll differential speed — performs a deterministic calculation from the provided inputs. No acceptance criterion is applied; the result is CALCULATED only.
Step 3: Calculate annual polymer mass reduction via dose optimization — compares engineering inputs against deterministic thresholds and produces a PASS or FAIL decision.

This tool coordinates 1 validation step and 2 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.

METHODS & EQUATIONS

All formulas are resolved from canonical runtime definitions and executed deterministically by the client-side engine.

Step 1: Compute minimum wash pressure to overcome cake–belt adhesion

Formulamax(0.15,(tau_cake*0.083)/(k_belt*v_belt*0.6))

Step 2: Calculate mechanical safety margin for scroll differential speed

Formula100*((tau_motor_max*eta_gear)/(0.012*J_bowl*pow(omega,2)*(TSS_peak/25)))-100

Step 3: Calculate annual polymer mass reduction via dose optimization

Manual Workflow

ΔM_poly = (D_curr − D_opt) × Q_annual × TSS_avg / 1,000,000; unit conversion: mg/kg_DS × m³/yr × g/L = mg × m³ × g / (kg_DS × yr × L) → since 1 kg_DS = 1000 g and 1 m³ = 1000 L, net factor = 10⁶; verified against Veolia Chemical Usage Audit Framework v3.1.

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.

WHEN TO USE THIS TOOL

When deterministic Biogas Digestate Separator engineering verification is needed for project-specific conditions.
For calculation of Compute minimum wash pressure to overcome cake–belt adhesion (Step 1).
For calculation of Calculate mechanical safety margin for scroll differential speed (Step 2).
For validation of Calculate annual polymer mass reduction via dose optimization (Step 3).
