Technical Perspective of Landfill Leachate Treatment via Membrane Distillation Using Waste Heat from Biogas Combustion for Power Generation.

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
In this study, we investigated the potential of using the combustion of biogas generated in landfills for power generation as an alternative waste heat resource for landfill leachate treatment. The effectiveness of direct-contact membrane distillation (DCMD) for wastewater treatment was also evaluated. The performance of DCMD was assessed based on conductivity, chemical oxygen demand (COD), and ammonia retention by testing both synthetic and raw landfill leachate. Results showed that the permeate stream had low COD (<0.5 mg/L) and turbidity (<1 NTU); however, ammoniacal nitrogen exceeded the maximum discharge limits defined by Brazilian legislation, indicating the need for additional treatment. Energy consumption analysis through simulations demonstrated that partial feed recycling in DCMD improved energy efficiency, achieving a gain output ratio (GOR) of 2.54 and reducing specific energy consumption (SEC) by 25%. The simulations showed that landfills producing more than 6.4 m
