Influence of polymeric materials on the performance of a mesophilic biotrickling filter treating an α‐pinene contaminated gas stream
Bibliographic record
Abstract
Abstract BACKGROUND Recent studies have characterized the most effective absorbent polymers for the removal of volatile hydrophobic pollutants from air. This study evaluates the performance of a laboratory scale α‐pinene‐degrading biotrickling filter ( BTF ) packed with lava rock. A second solid phase, Hytrel ® G3548L (5%, v/v), was added in order to check its effect on the performance of the system during long‐term operation. RESULTS The biodegradation profile was similar in both bioreactor configurations, with or without solid polymers, reaching a maximum elimination capacity ( EC max ) around 25.6 g m −3 h −1 when an inlet loading rate of 57.2 g m −3 h −1 was applied. Tracer studies were carried out in order to determine the effect of the liquid and gas velocities, and to analyze the gas distribution with the different packing materials. CONCLUSIONS Deviation from ideal flow caused by channelling of the fluid was observed from tracer studies. No better performance was observed under steady‐state conditions in the presence of polymeric Hytrel material. Further considerations are needed for the selection of an appropriate absorbent polymer for α‐pinene removal. © 2015 Society of Chemical Industry

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.
