• TECHNICAL NOTES 9 FLOTATION

    Particles enter the froth phase when a bubble carrying the particles crosses the pulpfroth interface The froth phase floats on top of the pulp phase and is formed by the bubbles that break through the surface of the pulp phase The water in the flotation cell is conditioned to promote the formation of a more or less stable froth The bubbles do not burst when they cross the interface and each one

    Overview
  • Dissolved air flotation Wikipedia

    Dissolved air flotation is a water treatment process that clarifies wastewaters by the removal of suspended matter such as oil or solids The removal is achieved by dissolving air in the water or wastewater under pressure and then releasing the air at atmospheric pressure in a flotation tank basin The released air forms tiny bubbles which adhere to the suspended matter causing the

  • Dissolved Air Flotation an overview | ScienceDirect Topics

    The flotation process is suitable for stop/start operation and has a flow turndown of about 2:1 or greater depending on the design of aeration manifolds The former is one of its advantages when dealing with a water subject to high algal loadings; a plant can be ‘switched in’ as and when needed and will give a steady quality treated water within 45 minutes ( Rees, 1979 )

    14082017· Vacuum flotation In vacuum flotation the process stream is saturated with air at atmospheric pressure and introduced to the flotation tank on which a vacuum is applied giving rise to the generation of the air bubbles The process can be run only as a batch process and requires sophisticated equipment to produce and maintain the vacuum By and large the amount of air released during flotation is limted by the vacuum achievable Pressure flotation In contrast to vacuum flotation
