Pilot Plant Study of Aqueous Linear Alkylbenzene Sulfonate Degradation by Combined Advance Oxidation and Biological Processes
Bibliographic record
Abstract
Photochemical degradation of linear alkybenzene sulfonate (LAS) using a pilot plant photoreactor is studied. LAS at 100 mg/L is degraded by UV-254 and UV/H2O2. Degradation of LAS is effectively enhanced by 720 mg/L H2O2. Moreover, the effectiveness of phototreatment on the biodegradability of LAS is examined. Both pretreated and untreated LAS are used in biological experiments. Combination of UV-254 with optimum concentration of H2O2 effectively enhanced the biodegradability of LAS. However, LAS at 100 mg/L can inhibit the growth of microorganisms. It is observed that the adaptation of activated sludge increases the biodegradation of LAS. However, due to the presence of intermediates in the effluent of the photoreactor, the biodegradability of this effluent is less than the biodegradability of the same as the concentration of untreated LAS. It is also observed that using the integration of UV/H2O2 and biological processes instead of single step of UV/H2O2, reduces the total residence time in chemical reactor while obtains the desired total efficiency.

How this classification was reachedexpand
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.
