Where first-principles models meet measured data, data-driven modelling adds prediction and live insight — digital twins, machine-learning surrogates, soft sensors and data reconciliation that turn a plant’s instrument history into forecasting, optimisation and early warning.
The questions this modelling discipline answers
A calibrated model running alongside the live plant, fed by SCADA, mirrors current state and tests changes virtually — a safe sandbox for optimisation and operator training.
Fast surrogate models, trained on simulation or plant data, approximate expensive mechanistic runs — enabling real-time optimisation and thousands of what-if cases.
Data-driven soft sensors infer hard-to-measure quality (effluent COD, sludge state) from routine signals, filling gaps between lab samples.
Pattern models flag drift, fouling and equipment degradation before they become a compliance or downtime event.
Mechanistic models (CFD, process, kinetic) encode physics and generalise well but need effort to build and run; data-driven models learn directly from a plant’s data and run instantly but only within the range they have seen. The strongest approach is hybrid: a digital twin couples a calibrated mechanistic model to live SCADA so the plant’s real behaviour continuously corrects the model, while surrogate models make the heavy physics fast enough for real-time optimisation, and soft sensors fill the gaps between lab results. Data reconciliation keeps everything honest by closing the measured mass balance against sensor error. Used well, this layer converts an instrumented plant from a source of alarms into a source of foresight.
Reynolds & Bauhm applies the right modelling discipline to the question — from a steady-state flowsheet to a calibrated digital twin — so design and operating decisions are made on evidence, not assumption.
