Aquacare designs and supplies five different types of Aquaculture Biofilters:

For nitrification

Microbead biofilters: utilizing expanded polystyrene beads as large surface area. Highly effective and stable, compact, very low head, very economical media. Can integrate CO2 stripping.

Moving bed biofilters: utilizing plastic media, agitated using air or water jet. Highly effective and stable.

Fluidized biofilters: sand media fluidized by water flow. Highly effective, low cost media, higher pumping head required.

Trickle filter biofilters: passive filters with and without countercurrent air flow. Simple and effective, requires large area.

For denitrification

Multi-cell biofilters with automatic carbon source dosing. Bacteria are first starved of oxygen, then with the addition of supplemental carbon source remove the O from NO3. Carbon addition is controlled using an ORP sensor feedback loop.

Aquacare will recommend the best biofilter for each application.
