Abstract
A decoupled aquaponic system having two loop subsystems: hydroponic (Hp-loop) (2) and aquaculture (RAS) (1) interconnected by a third loop subsystem performing reverse osmosis filtration (OI) of RAS (1) recirculation water to achieve a higher nutrient quantity in the former and higher quality recycled water in the latter, with consequent energy savings due to its variable control structure and OI membrane effectiveness. Prior to entering the system containing the OI membrane, a water ultrafiltration (UF) (22) treatment is added to preserve its lifespan.
Claims28
A decoupled aquaponic system characterized in that it comprises:
- a recirculating aquaculture subsystem (RAS loop) consisting of a fish tank unit;
- a hydroponic subsystem (Hp-loop) and
- a third loop (OI) that performs reverse osmosis membrane filtration treatment (OI) connecting both subsystems,
- wherein the fish are freshwater fish and the plants are vegetables, fruits, cole crops, inflorescence, bulbs, stems, ornamentals, or forage crops susceptible to be grown hydroponically,
- wherein the recirculating aquaculture subsystem (RAS loop) and the hydroponic subsystem (Hp-loop) are linked by means of the third loop (OI), both subsystems being in fluid communication with the OI membrane that distributes the salt-rich solution (reject) containing N and P to the Hp-loop and the desalinated water (permeate) back to the RAS.
