  • BIOLOGICAL FILTERS FOR AQUACULTURE

    In contrast, fluidized bed sand filters have been successfully used for aquaculture applications. A sand filter becomes fluidized when the velocity of the water flowing up through the bed is sufficient to raise the grains of sand up and separate each grain from its neighbors.

  • Fluidized bed - Wikipedia

    The resulting phenomenon is called fluidization.Fluidised beds are used for several purposes, such as fluidized bed reactors (types of chemical reactors), solids separation, fluid catalytic cracking, fluidized bed combustion, heat or mass transfer or interface modification, such as applying a coating onto solid items. This technique is also becoming more common in aquaculture for the ...

    where fluidized bed filters really stand apart from other filters. The fine sand media in a fluidized bed biofilter provides an extremely high surface area (7,800 ft2/ft3) and acts as a thin film reactor. This enables the biofilter to remove up to 100% of the ammonia per pass and allows the system to be shock-loaded without any changes in overall water quality. In addition to nitrification ...

    Fluidized bed filters are essentially sand filters operated continuously in an expanded backwash mode. Water flows up through a bed of sand at a rate sufficient to lift and expand or fluidize the sand and keep the particles in motion so they no longer are in continuous contact with each other. Fluidized bed filters use low-cost sand of smaller diameter than that used in particulate solids ...
