Odor removal via high-speed biofiltration in headwork operations of wastewater treatment plants.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Biofiltration process has proved being an effective, low-cost, and environmental friendly method to remove odor pollution in wastewater treatment plants (WWTPs). Despite its assets, this technology is often limited due to the required surface area for biofilters. The main aim of this study was to study the biofiltration of foul air at high velocities (or low empty bed retention time, EBRT) as an option to reduce the surface area requirement of the deodorization process. To do so, a pilot-scale biofilter was built and operated with foul air coming from the headworks of a WWTP located at Cannes (France) at velocities ranged from 500 to 1400 m/h equivalent to 10-4 s of EBRT, respectively. The concentrations of pollutants ranged from 0 to 140.75 mg/m
