Abstract

fetched live from OpenAlex

Physical cleaning methods generally involve applying hydraulic or mechanical forces to dislodge and remove foulants from the membrane surface. In the course of filtration, diverse phenomena might occur, causing the reduction of the membrane performance. The deposition of solutes and/or particles onto the membrane surface (cake layer formation) or into membrane pores (pore blocking) is one of the main challenges in the operation of membranes, causing flux decrease and/or the increase of the transmembrane pressure (TMP). Whereas physical cleaning can remove reversible fouling, the irreversible one can be only reduced by chemical cleaning. Conventional physical cleaning techniques are based either on hydraulic (forward and reverse flushing, backwashing, membrane relaxation, and air flushing) or mechanical (sponge ball and fluidized particle cleaning) methods. Regarding the cleaning by sponge balls and fluidized particles please refer to mechanical cleaning. Ultrasonic and electrical...

Not 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.
