Abstract
Tailings pond water produced from the extraction of bitumen from the oil sands in Northern Alberta, Canada, was treated using the spray freezing process. The wastewater was frozen by spraying at 10°C and 24°C ambient temperatures. The effect of the degree of freezing (i.e., freezing with and without runoff generation) of the sprayed water on the treatment efficiency, the concentration, and distribution of the impurities within the ice columns was examined. When the sprayed water only partially froze (i.e., freezing with runoff formation), the treatment efficiency (measured by reduction in COD, TOC, conductivity, Cl , SO 4 2 concentrations) was higher and larger volumes of high quality meltwater was obtained. Reduction of toxicity (Microtox) in meltwater, and the relationship between the overall impurity removal and toxicity reduction was also examined in this study. The decay coefficients were determined for prediction of meltwater impurity concentrations using mathematical models.Key words: spray freezing, wastewater treatment, oil sands tailings pond, toxicity reduction.

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
