BioFOAM Biological Filters
BioFOAM biofilters combine "Moving-Bed" biofiltering with protein skimming to create a very effective biological filter system. The "Moving-Bed" biofilter
utilizes suspended media, which eliminates the possibility of a channeling media bed. Additionally, a by-product of this process, foam collimates/separates
at the top of the filter vessel, taking dissolved organic wastes up and out of the filter. The result: Optimum nitrification, improved water clarity and
dissolved oxygen saturation.
- Moving-Bed Biofiltration creates an ideal environment for
nitrifying aerobic bacteria colonies
- Will not channel or pack down the media bed
- Removes small suspended waste particles
- Removes dissolved organic waste
- Increases dissolved oxygen level
BioFOAM "Moving-Bed" Biofilter Operation
Water from the livestock tank is continuously circulated inside the BioFOAM Filter. An independent
pump recirculates water inside the BioFOAM reactor via an air venturi manifold. The oxygenated water suspends and tumbles the media, providing an optimal
environment for colonizing nitrifying bacteria.
The oxygen-rich water inside the BioFOAM reactor contains micro-fine air bubbles that travel upward
through the reactor, accumulating both small particles and dissolved organic waste on their bubble walls. These tiny air bubbles not only help to suspend
and move the media bed, but also increase dissolved oxygen. This process ultimately creates a dense foam at the top of the filter. This waste-laden foam
separates from the system's water as it climbs up and out of the waste tube.
