Aquacare Biofilters

 

 

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

We design and supply 5 different types of Aquaculture Biofilters:

MICROPORE BIOFILTER

*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 conventional plastic media, agitated using air. Highly effective and stable.

FLUIDIZED BIOFILTER

*NITRIFICATION

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

TRICKLE FILTER BIOFILTER

*NITRIFICATION

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

MULTI-CELL BIOFILTER

*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.
