Effect of Dissolved Air Flotation on Algae Removal in Seawater Desalination Pretreatment During Harmful Algal Blooms.
Article in Water environment research : a research publication of the Water Environment Federation, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
To secure the stable operation of seawater reverse osmosis during harmful algal blooms (HABs), this pilot-scale study evaluated an emergency pretreatment strategy combining sodium hypochlorite (NaClO) pre-oxidation, dissolved air flotation (DAF) and postsand filtration (SF) to optimize algae and turbidity removal. Results demonstrated that moderate NaClO pre-oxidation effectively avoided the risk of flocculant oxidation while enhancing algal and turbidity removal by approximately 6% and 18% after DAF, respectively. About 12 mg/L polyaluminum chloride (PAC) and 15 mg/L FeCl
