Abstract
An integrated biofilter for a re-circulating aquaculture system is provided. The biofilter may include a moving bed biofilm reactor (MBBR) with biomedia elements configured to support bacteria growth and nitrification of the wastewater and an MBBR output configured to output biomass generated by the bacteria. The biofilter may also comprise a periphyton biofilter configured to introduce oxygen into the wastewater, and a halophyte biofilter comprising a plurality of plants. The halophyte biofilter configured to capture nutrients in the wastewater to generate edible plant mass.
Claims17
A land-based re-circulating aquaculture system comprising:
- a tank having a tank input and a tank output;
- a filter operably coupled between the tank output and the tank input;
- a pump operably coupled between the tank output and the tank input and configured to pump wastewater from the tank output through the filter to the tank input;
- and
- a solids removal unit operably coupled to the pump and configured to remove solids from the wastewater exiting the tank output;
- wherein the filter comprises:
- a moving bed biofilm reactor (MBBR) comprising:
- biomedia elements configured to support bacteria growth and nitrification of the wastewater;
- and
- an MBBR output configured to output biomass generated by the bacteria;
- a periphyton biofilter configured to introduce oxygen into the wastewater;
- and
- a halophyte biofilter configured to capture nutrients in the wastewater to generate edible plant mass.
An integrated biofilter for a re-circulating aquaculture system, the biofilter comprising:
- a moving bed biofilm reactor (MBBR) comprising:
- biomedia elements configured to support bacteria growth and nitrification of the wastewater;
- and
- an MBBR output configured to output biomass generated by the bacteria;
- a periphyton biofilter configured to introduce oxygen into the wastewater;
- and
- a halophyte biofilter comprising a plurality of plants, the halophyte biofilter configured to capture nutrients in the wastewater to generate edible plant mass.
A method for operating a re-circulating aquaculture system, the method comprising:
- pumping wastewater from an aquaculture tank out of a tank output to an integrated biofilter;
- removing solids from the wastewater exiting the tank output;
- passing the wastewater through the integrated biofilter to generate treated water, wherein passing the wastewater through the integrated biofilter comprises:
- passing the wastewater through a moving bed biofilm reactor (MBBR) comprising biomedia elements configured to support bacteria growth and nitrification of the wastewater;
- passing the wastewater through a periphyton biofilter configured to introduce oxygen into the wastewater;
- and
- passing the wastewater through a halophyte biofilter comprising a plurality of plants, the halophyte biofilter configured to capture nutrients in the wastewater to generate edible plant mass;
- and
- returning the treated water to the tank via a tank input.
