摘要: Abstract Toxic cyanobacteria blooms are associated with nutrient enrichment of surface waters. Nanofiltration (NF) is a pressure-driven process that can be used in water treatment plants, to effectively remove particulate matter and organic contaminants, including toxins, nutrients. NF produces toxin-enriched stream, e.g. microcystin-LR (MC-LR), has safely disposed of. The suitability the electrodialytic (ED) for phosphorus recovery decrease MC-LR concentrations from waste stream was assessed. In ED experiments running between 5 12 h, electromigrated towards anode compartment promoting an isolated clean product. maximum obtained 84%, varying (membrane concentrate) characteristics, cell design time. After application concentration also reduced. These results encourage further tests, aiming inclusion this hybrid technology (NF followed by ED) contributing not only recovery, but toxicity concentrate, lowering costs safe disposal.
