Physical Model Testing Of An Experimental Vortex Device For Controlling Total Suspended Solids In Stormwater
Bibliographic record
Abstract
In highly urbanized area, lack of space limits the application of most stormwater quality treatment technologies. Oil/Grit Separators (OGSs) are preferred in these cases due to their compact size and reasonable solids removal efficiency. The objective of this research is to identify the challenges and practical potential solutions of solids treatment performance testing on a full-scaled experimental vortex device (EVD) adopting TRCA’s regulatory guideline titled the “Procedure for Laboratory Testing of Oil/Grit Separators” (referred to in this paper as the Procedure) which stipulates the standards of sediments and oil removal tests in Canada. The test results indicated that: (1) TSS treatment efficiency of EVD was observed to decline with the particle size and flow rate; and (2) the average overall TSS treatment efficiency decreased from 52% to 44% as the flow rate doubled.

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.
