Design a bioelectrochemical resource-recovery system
Start with a wastewater stream. Get a ranked system suggestion via the 5-physics-family router. See a real ML prediction with conformal bounds, an OOD flag, and a prior-trust badge. Trace every number to its source artifact.

Section 1 · Influent characterisation
Define the wastewater stream
Six industrial archetypes or set parameters within their literature ranges. Each slider shows hard bounds, typical band, sub-ranges by facility type, and the active preset's target value.
Section 2 · System suggestion
Pick a coupled architecture
Ranked by influent fit using the 5-physics-family router. Click a card to drive every downstream panel.

Section 4 · Live prediction · /api/ml/predict
Real ML stack, honest bounds
Section 5 · Recovery balance
What this system actually recovers
Daily mass + energy flux from first-principles balance on the influent and the live prediction. Hover any band for source.
- · Using literature-midpoint fallback for power density.
- · COD removal from archetype default (80%).
Section 7 · Design recommendations
Apply a recommended change
Stage a recommendation to see it as a ghost overlay in 3D. Apply to commit it to the scenario.
Section 8 · Sensitivity ladder
Which knob moves the needle
Within-paper Bayesian effects from within-paper-effects.json. Each β is the population-level effect on the target after partialling out paper-level confounds. Sign matters — green increases, red decreases.
Section 9 · Calibration · honest caveats
What this model is — and isn't — calibrated for
What we don't claim
- •MDC, MES, MNRC, MMRC, MBES are not in the 97.98% OOS holdout — analytical predictors only.
- •TEA numbers are literature midpoints; not a contracted quote. Site engineering adds 20–40%.
- •COD removal predictions are coarse for high-strength industrial streams with toxic shocks.
- •No predictions of micropollutant removal, antibiotic resistance, or pathogen fate.
- •Long-term biofouling, electrode degradation > 12 months are absent from the corpus.
Section 10 · Mini-TEA · MFC + Anaerobic Digestion
What it costs
From the archetype's Process-TEA baseline. Discount rate 0.1, lifetime 15 yr. Honest disclaimer: literature midpoints, not a contracted quote.
- · Electrode capex $1,200/m² (carbon-cloth, Logan 2008 inflated).
- · Performance inputs are stub literature midpoints — wire to a sweep export for real numbers.
- · Higher 10 % discount rate reflects MFC scale-up risk (Santoro 2017).
