Nitrifying bacteria addition into reactors operating near washout conditions for nitrification
Bibliographic record
Abstract
Sequencing batch reactors, at 10 °C, operating near the minimum solids retention time (washout conditions) for nitrification, were seeded daily with nitrifying biomass acclimated to 10 and 20 °C. Effluent NH 3 -N levels were decreased to less than 5 mg/L within 23 d for both seeding regimes. Once seeding was terminated, the reactor seeded with nitrifying bacteria acclimated to 10 °C continued to achieve full nitrification, whereas the reactor seeded with nitrifiers acclimated to 20 °C saw a rapid increase in effluent NH 3 -N concentrations. Nitrification was not completely lost in the latter reactor after seeding was stopped for 30 d. Key words: nitrification, bioaugmentation, temperature, solids retention time (SRT), dewatering liquor, wastewater.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
