Abstract
Investigations were carried out recently in three Canadian newsprint mills where a cationic dual polymer retention chemistry was in use for years. Several enhancer/PEO combinations were evaluated on bench scale to determine any possibility for replacing the existing retention system for reduced chemical cost and improved machine operating efficiency.The PEO with 10 million molecular weight was more effective than that of 7 million molecular weight. New enhancers produced from bisphenol-S. especially EnhancerB were much superior to the traditional phenol-formaldehyde resin in promoting PEO retention performance. The effect of stock aging on retention appeared to be stock dependent.The non-ionic retention chemistry improved stock drainage more than the mills cationic dual polymer system even at much lower dosage levels, as determined with a Vertical sludge press. The new enhancer/PEO combination was proved once again to be excellent for pitch removal and was considerably better than that of two cationic dual polymer systems studied.

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
