Study of Membrane Transport for Hemodiafilter and Reverse Osmosis Module
Bibliographic record
Abstract
As a typical membrane technology by which the solute substances are separated from a solution, hemodiafilter and reverse osmosis module are studied, in particular regarding the solute transport through the membrane. The solute transport equation, as a key point of this paper, could be derived from the modified Kedem-Katchalsky equation combined with Film theory model. As the next key point for the numerical analysis, the solute transport equation was inserted into the previous module model, and the differential equations composing this module model were converted to the difference equations calculated with a nonlinear secant method. Then the solute concentration profiles of the membrane and the boundary layers in the hemodiafilter and the reverse osmosis module were obtained to visually illustrate in Figures 3 to 6. Finally, it was clear that the occurrence of concentration polarization in the boundary layer is dependent on values of the membrane parameters, including solute permeability (Pm) and reflection coefficient (σ), the ultrafiltration flux (Jv) and the mass transfer coefficient (k).

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
