Recirculating aquaculture systems (RAS) are used in home aquaria and for fish production where water exchange is limited and the use of biofiltration is required to reduce ammonia toxicity. Other types of filtration and environmental control are often also necessary to maintain clean water and provide a suitable habitat for fish. The main benefit of RAS is the ability to reduce the need for fresh, clean water while still maintaining a healthy environment for fish. To be operated economically commercial RAS must have high fish stocking densities, and many researchers are currently conducting studies to determine if RAS is a viable form of intensive aquaculture.

The present invention relates to a novel approach for nitrate removal from a marine recirculating system (10) wherein high concentrations of sulfate found in seawater is used in combination with sludge (20) collected from fish growing tanks (12) to promote dissimilatory sulfate reduction to hydrogen sulfide. The sulfide is used as an electron source to promote autotrophic denitrification in an up-flow fix bed bioreactor (16), followed by nitrification in a nitrification unit (14). By utilizing the symbiotic relationship between the sulfate-reducing and sulfide-oxidizing bacterial community, nitrate accumulation is controlled in the recirculating water of the system thereby reducing water exchange in the marine recirculating system.

Novel Arrangement of Denitrification Reactors in a Recirculating Aquaculture System
ActiveUS20090152192A1Maximize survivalSure easyWater treatment parameter controlSpecific water treatment objectivesAquatic speciesFiltration
The present invention relates to a novel arrangement of denitrification reactors for removal of nitrate compounds in a recirculating aquaculture system. The novel arrangement of an aquaculture system of the present invention includes positioning one or more anaerobic denitrification reactors upstream of aerobic nitrification and degassing processes. One aspect of the present invention includes a flow of aqueous medium from aquatic species rearing tanks towards one or more denitrification reactors. Another aspect of the present invention includes flow of aqueous medium from aquatic species rearing tanks to a solids removing filter or mechanical filtration means for removal of solid waste matter or biomass prior to flow of aqueous medium towards one or more denitrification reactors. In a sequence of components comprising a system of the present invention, treated and denitrified aqueous medium exiting one or more denitrification reactors is directed towards a solids removing filter wherein treated and denitrified aqueous medium combines with untreated aqueous medium. Combined untreated aqueous medium and denitrified aqueous medium exits a solids removing filter and is directed towards an aerobic nitrification unit. Aqueous medium exiting the aerobic nitrification unit is degassed and oxygenated and returned to aquatic species rearing tanks. A system of the present invention which utilizes denitrification reactors positioned upstream of aerobic nitrification has advantages over existing aquaculture systems which use denitrification in reduction of nitrate concentrations. This results in greater mitigation of water chemistries and compounds which are harmful to aquatic species and more efficient use and conservation of water resources.
