Abstract

fetched live from OpenAlex

Four surface drinking water sources were selected to investigate the impact of strong base anion (SBA) exchange resins—as a pretreatment to ultraviolet/hydrogen peroxide (UV/H 2 O 2 )—on dissolved organic carbon (DOC), nitrate, UV transmittance, and hydroxyl radical (·OH) scavenging of the water samples. Results demonstrated good efficiency of SBA exchange resins at increasing UV transmittance (up to 75%) and reducing DOC (up to 80%), nitrate (up to 75%), and sulfate (up to 75%) within the ion exchange (IX) conditions applied. Additionally, data confirmed the positive effect of IX treatment at reducing the ·OH scavenging characteristics of the water, especially for high‐DOC/low‐transmittance water sources. Electrical energy per order for removing a probe compound (4‐chlorobenzoic acid) was reduced 20 to 40%, indicating improvement in the efficacy of UV/H 2 O 2 treatment. Study findings demonstrated the potential of using the IX process to improve the quality of water undergoing UV/H 2 O 2 treatment and its subsequent benefits on UV/H 2 O 2 efficacy and electrical energy consumption.

Teacher imitation

Not 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.
