Abstract: A water treatment system for a recirculation aquaculture facility, related method and uses thereof are provided. The water treatment system included a water pre-treatment facility and a groundwater recharge arrangement, wherein the water treatment system forms a primary recirculation flow pathway when integrated with the recirculation aquaculture facility, thereupon effluent discharged from the recirculation aquaculture facility is sequentially directed through and back into the recirculation aquaculture facility via a water collecting circuit network to enter the recirculation aquaculture facility as an influent. The secondary recirculation flow pathway is formed internally within the recirculation aquaculture facility.

Abstract: A circulation and aeration system 10 for an aquaculture facility including an elongated reservoir for cultivating aquatic species is provided. The system includes a number of vertical manifolds distributed along the length of the reservoir through an interconnecting piping and arranged to generate a number of adjacent rotating liquid flow patterns by injecting aerated water into the reservoir via exhaust ports, wherein each the pattern forms an individual rotating flow cell, and wherein the system further includes at least one airlift pump configured to supply the aerated water into the manifolds. Related facility, methods and uses are further provided.
