Dispersed air flotation of microalgae using venturi tube ...

2019-11-1  Dispersed air flotation has a clear advantage over dissolved air flotation in that it does not require energy to pressurize the culture fluid. Hanotu et al. separated microalgal culture fluid by dispersed air flotation to investigate the effect of coagulants and pH conditions on the removal efficiency of solids.

Dispersed air flocculation/floatation for stripping of ...

A laboratory-scale dispersed air floatator was developed for the stripping of organic pollutants from various effluents from sewage works, fish factories, pulp and paper mills and abattoirs. A modified dispersed air generating system was developed simply by suction of air into the pump impeller thus avoiding high pressure floatation equipment.

Dissolved Air Flotation - an overview ScienceDirect Topics

Dissolved air is the most common type of flotation gas used in potable water treatment. The dissolved air flotation (DAF) process mixes a clarified stream from the outlet of the unit with air at 3–9 bar, to produce a supersaturated (compared with saturation at atmospheric pressure) solution of air in water.

2013-5-1  Dispersed air flotation of algal suspension. Dispersed air flotation experiment was conducted using a flotation column (inside diameter of 5 cm and 47 cm in length). Nitrogen gas was directed into the column through a porous glass sparger with pore diameter of 30–60 μm. The flow rate of nitrogen was kept at 80 mL/min. All flotation ...

CONCLUSION: The present work demonstrated that electroflocculation integrated with dispersed-air flotation is a promising method suitable for microalgae harvesting. The strategic air supply obviously shortened the algal recovery time in the process of electroflocculation due to facilitating algal aggregation and flotation to the solution surface.
