Abstract
A full-scale trial of micro-aeration was conducted at a municipal wastewater plant using two anaerobic digesters with limited headspace, one as a control and one as a test. A reduction of approximately 13 %–16 % in hydrogen sulfide biogas concentrations was observed in the test digester. Microbial community analyses were also conducted at steady-state conditions to determine differences between the microbial ecology of the test and the control digesters. Although sulfide removal typically occurs in the headspace of a micro-aerated digester, the data generated by this pilot study developed a new approach to quantify the contribution of liquid phase sulfide oxidizing microbes (SOM).

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
