Piloting of a deammonification moving bed biofilm reactor for mainstream industrial wastewater application
Bibliographic record
Abstract
The City of Portage la Prairie is required to meet the Province of Manitoba’s new effluent limits of 1 mg/L total phosphorus and 15 mg/L total nitrogen at their Water Pollution Control Facility (WPCF) and will need an upgrade to achieve this. Industrial flows to the system contribute approximately 90% of the N and P loads. To investigate methods to reduce these loads, piloting of the Ostara Pearl® struvite crystallization and Veolia ANITAMox deammonification systems was performed. The objective of this thesis was to pilot the ANITAMox system for seven months and determine the impact of the following process conditions: reduced influent temperature; increased pH; periodic high influent TSS concentrations; and modifications to the ANITAMox process train comprising of elimination of the pretreatment BOD removal reactor. It was found that deammonification could be an option for reducing mainstream ammonia loading from industrial flows at the WPCF.

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.
