Use of water primrose (Jussiaea repens L.) for treatment of some pollutants in domestic wastewater under laboratory condition
Bibliographic record
Abstract
The objective of this study was to examine the abilities of Jussiaea repens L. in removing organic compounds, nitrogen and phosphorus from domestic wastewater under laboratory conditions. The experimental model consisted of four plastic tanks, each measuring 52 x 32 x 27.5 cm, labeled as NT1, NT2, and NT3 corresponding to 150, 300, and 450 g of Jussiaea repens L., respectively. The control tank contained only domestic wastewater without the plants. The input domestic wastewater parameters (mean ± standard deviation, n = 3) were as follows: pH = 6.66 ± 0.32, BOD5 (Biological oxygen demand) = 347.64 ± 39.60 mg/L, NH4+ = 27.53 ± 1.74 mg/L, NO3- = 2.23 ± 0.26 mg/L, and PO43- = 24.69 ± 1.27 mg/L. After twenty days of experimentation, the tank containing 450 g of plants achieved the highest treatment efficiencies for BOD5, NH4+ and NO3-, with respective efficiencies of 29.1, 24.2, and 43.8%. Regarding phosphate removal, the tank (NT2) using 300 g of plants achieved the highest treatment efficiency (by plants), with a reduction of 9.5% after 20 days.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
