Biofilters recirculate aquaculture water and support the further growth of aquaculture products without excessive, environmentally unsustainable water demands.

We design & supply 5 different types of Aquaculture Biofilters

MICROBEAD BIOFITER

*NITRIFICATION

Utilizing polyethylene micropore disk media with ultra high protected surface area. Highly effective and stable, compact,very low head, very economical media. Integrates CO2 stripping.


MOVING BED BIOFILTER

*NITRIFICATION

Utilizing plastic media, agitated using air or water jet. Highly effective and stable.


FLUIDIZED BIOFITER

*NITRIFICATION

Sand media fluidized by water flow. Highly effective, low cost media, higher pumping head required.


TRICKLE FILTER BIOFITER

*NITRIFICATION

Passive filters with and without countercurrent air flow. Simple and effective, requires large area.


MULTI-CELL BIOFITER

*DENITRIFICATION

Multi-cell biofilters have 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.
