Abstract

fetched live from OpenAlex

Fouling of membrane is the major scientific lock for electromembrane process intensification limiting their applications. The fouling evolution on ion-exchange membranes was monitored during three consecutive electrodialysis treatments of a solution containing a high magnesium/calcium ratio. Following these experiments, we proposed a mechanism to explain the change in fouling nature on the CEM from a mix of calcite, brucite, and portlandite after the first ED run to a predominant amorphous Mg(OH)(2) after the third run and the formation of calcite cubic crystal on the AEM, although Mg(2+), an inhibitor of CaCO(3) formation, was present in the solution. It was also demonstrated that the nature and structure of the AEM and CEM foulings formed were self-oriented by the formation of the CEM first layer of fouling appearing during the first run. Our findings have implications for electromembrane process fouling control as well as in the understanding of CaCO(3) crystallization phenomena.

Teacher imitation

Not 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.
