1 · What the graph read from it

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.

2 · The registry

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

The zero-valent iron-anaerobic ammonium oxidation (ZVI-anammox) system has received widespread attention due to its excellent nitrogen removal performance and user-friendly operation. However, its disadvantages include a short service life, high ZVI consumption, and poor system stability. The use of ultrasound as a physical method is increasing in various water treatment processes. In this study, a series of batch tests were conducted to obtain the best ultrasonic parameter and explore the comprehensive effects of ultrasound on a ZVI-anammox system. The highest specific anammox activity of the ZVI-anammox system was found to be 2.88 mg total nitrogen/g of volatile suspended solids/h after ultrasonic treatment (0.2 w/mL, 5 min), which was 37.85% higher than a control group. Additionally, the service life of ZVI extended by 28.57% and the total nitrogen removal efficiency changed from 58.03-72.08 to 63.92-78.33% under ultrasonic irradiation. These phenomena were related to the mechanical force and cavitation of ultrasonic waves. Judging from the characteristics of sludge and ZVI, ultrasound can promote anammox sludge granulation, ease ZVI passivation, and enhance the stability of the entire system. This paper also briefly discusses the impact mechanisms of ultrasound on the ZVI-anammox system. In brief, ultrasound destroys the surface structure of ZVI and thus provides numerous attachment points for microorganisms that improve the performance of the entire system. The proposed ultrasound combined with ZVI is a novel method that has potential for use in large-scale engineering applications in actual sewage treatment after comprehensive analysis.
