Effect of Additives on Biological Treatment of Landfill Leachate
Bibliographic record
Abstract
Abstract Aerobic batch bioreactors were used in this research to study the effects of different additives on the biological treatment of landfill leachate. Those additives were phosphoric acid, powdered activated carbon, polyethylenimine and BOD Balance™. Both synthetic and natural landfill leachates were investigated. The natural leachate was collected at a landfill site near London, Ontario. It was observed that the addition of phosphoric acid increased the COD utilization rate as well as decreased the effluent COD. The other additives did not affect the effluent COD but were found to have a small influence on the COD utilization rates, especially PEI and BOD Balance. A maximum average COD utilization rate of 90 mg L-1 h-1 was obtained with the following combination of additives: phosphoric acid and BOD Balance at 5 mg L-1.

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.
