- Fluidized Bed Filter Aquaculture
In addition to biochemical properties of the aquaculture solids and associated supernatant, system design influences N removal in denitrification biofilters. Fluidized beds, which are widely used for nitrification in RAS (Summerfelt, 2006), present a novel option for denitrification treatment. The very high specific surface area provided within ...

Fluidized bed filters are rapidly becoming the primary source of biological filtration in many modern aquaculture systems, replacing the less efficient "trickle" filters now in service. While trickle filters and fluidized beds both rely upon the same species of bacteria for ammonia and nitrite removal, it's how the two filters operate that sets ...
