Aerobic treatment of wastewater: Removal of nitrogen and phosphorus in the presence of humic substances
Bibliographic record
Abstract
This paper describes results of studies on the removal of ammonia (NH3-N) and phosphorus (T-P) during biological treatment of wastewater in the presence of humic substances (humate). Initial respirometric tests indicated that the investigated system complied with the Haldane model for inhibitory wastes. Addition of humate mitigated the inhibitory effect of the wastewater on the returned activated sludge (RAS), resulting in an increased biological oxygen uptake and in better removal of NH3-N and T-P. In the presence of 2000 mg l(-1) of humate, the system complied with the Monod model for non-inhibitory wastes and both NH3-N and T-P were almost completely removed. It is suggested that an application of humic substances has great potential as a simple and inexpensive method to reduce the nutrient levels in water, and also allow the recycling of phosphorus, incorporated into an organic fertilizer.

How this classification was reachedexpand
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.
