500,400 industrial SCADA records—preserved, indexed and ready for replay.

GFIS now holds one-minute operational history from the full-scale Muscatine, Iowa water resource recovery facility co-digesting industrial organic wastes.

What the dataset adds

500,400
Immutable raw rows

One-minute records spanning 18 March 2022 to 28 February 2023.

491,761
Published clean modelling set

The associated study reports this count after preparation. It is not the raw-file row count.

27
SCADA channels

Temperatures, flows, digester levels, total biogas and burner/boiler distribution.

Target boundary: the SCADA Biogas channel is total biogas flow in CFM. It is not methane. GFIS does not relabel it or merge it with the DS-05 measured-methane target.

Two complementary evidence streams

DS-05 · Mar–Jul research reactors
Measured CH₄ composition
Methane target + model comparison
DS-06 · full-scale SCADA
Industrial replay + future biogas benchmark

DS-05 supplies 138 controlled reactor records and 86 measured methane targets for chronological persistence, XGBoost and LSTM comparison. DS-06 supplies plant-scale operational density. Their targets and cadences remain separate.

Data engineering that can be defended

Immutable source

The 85 MB raw CSV remains unchanged. SHA-256: 8d56ac54…04440.

Order made explicit

The physical CSV row order is not chronological. Replay orders timestamps before applying any stride.

All rows queryable

A 500,400-row SSD SQLite index provides pagination without sending the full file to the browser.

Quality audit

Zero invalid timestamps, zero duplicate timestamps and 19 non-one-minute discontinuities.

Plant-twin contract

Temperature, feed and gas channels can drive observed replay; simulated states stay separately labelled.

Next benchmark

Reproduce the published cleaning procedure before chronological total-biogas model training.

The digital twin connection

The 3D plant is the visual state layer. An evidence adapter maps measured SCADA channels to equipment state, a Level 2 engine generates scenario trajectories, and experiment memory stores the source, timestamp, configuration and output. Observed and simulated modes are visibly distinct.

Biology animation: hydrolysis → acidogenesis → acetogenesis → methanogenesis is an explanatory animation, not microscopic measurement. Gasification: a separate high-temperature thermochemical train; it must not be depicted inside the anaerobic digester.
Working GFIS WebGL anaerobic-digestion plant twin
Working WebGL plant view connected to GFIS replay. Equipment animation is product evidence; the selected DS-05 timestamp is measurement evidence.
GFIS plant twin with methanogenesis-stage explanation
The biological-stage overlay explains hydrolysis through methanogenesis without representing particles as direct sensor observations.
