  • What is flocculation flotation?
  • 2.2. Flocculation–flotation (FF) The FF reactor is a special design (zigzag or static mixer type) for generating light flocs (aerated flocs) that are formed in the presence of polymers, air bubbles (injected air), high shearing force and a high head loss (or velocity gradient) ( Da Rosa and Rubio, 2005, Rubio, 2003, Rubio et al., 2002 ).
  • How floatation technology can be used in mining and industrial wastewater treatment?
  • Flotation technology can be incorporated in mining and industrial wastewater-treatment schemes in the following ways: as a unit process (ancillary or main process) to remove contaminants which are not separated by other means. Depending on performance (water quality), process water can be adequately treated and recycled;
  • Do aerated flocs improve flocculation–flotation processes?
  • In this context, various important research studies have demonstrated significant improvements in the flocculation–flotation processes. These improvements were mainly from the generation of aerated flocs (also namely, aeroflocs), which are the central subjects of this short review.
  • What is flotation process in wastewater treatment?
  • Flotation process in wastewater treatment Flotation had its beginning in mineral (ore) processing and as such has been used for a long time in solid/solid separation applications using stable froths to selectively separate different minerals from each other ( Kitchener, 1985 ).
