Abstract
Membrane bioreactor (MBR) package systems are providing affordable and simple-to-use decentralized wastewater treatment solutions for small to medium sized communities that face the challenge of balancing environmental and regulatory responsibilities with budgetary limitations. With a greater confidence and understanding of MBR technology, there is an increasing incentive in using MBR technology for these types of applications. Furthermore, valued qualities such as compact footprint, quick installation and start-up, process reliability, ease of operation, and superior effluent quality suitable for direct surface discharge and water reclamation have made MBR package system a preferred solution for decentralized wastewater treatment applications. This paper presents a retrofit solution for the Whitehouse Terrace Wastewater Treatment Plant. The existing extended aeration activated sludge package plant was retrofitted with a pre-engineered newterra MicroClearTM MBR package system for a small community along St Lawrence River in Brockville, Ontario. Five years full scale operation data of the MBR package system is presented and it is evident that the MBR package system consistently delivered high quality effluent that is far better than the required limit for direct surface water discharge to the St. Lawrence's river, with average effluent quality of 2.4, 2.6, 0.5, 0.05 mg/L, 1.7 counts/100 mL and 7.4 for biochemical oxygen demand, TSS, TP, TAN, Escherichia coli and pH, respectively.

Full frame distilled prediction
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
