Abstract: The present invention relates to a floating media moving bed portable biofilter and degasser and methods of using same useful for the biological treatment of aqueous nitrogenous waste. Provided herein are enhanced biofilter systems and methods for removing nitrogenous wastes from bodies of water. The portable biofilters described herein remedy the deficiencies of existing biofilters described above due to their enhanced nitrogen removing efficiency coupled with their simple and robust design, relative inexpensiveness, portability, ease of cleaning and maintenance, minimized trapping of aqueous solids, minimization of off-flavors in aquacultured fish, and immediate functionality when transferred to different sources of water. These advantages render the portable biofilters of the present invention suitable for commercial applications for aqueous nitrogenous waste removal.

Abstract: 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.

Abstract: One or more hoses (10) belong to the ventilation system which through a perforation are constructed at least partially as ventilation hose (60). Each of the hoses is permanently connected with a number of holding devices distributed over its length, which hold the hose (10) from below. The holding devices run in a guide rail (14). The hose (10) is drawn into the empty or liquid-filled basin (10) with a traction device along the guide rail (14) which introduces the tractive force onto the body of the hose and holds it there without prestress.

Abstract: A water treatment module (14) has a sedimentation compartment (20), into which water is introduced under high pressure. A filter or microsieve (1) can be provided upstream of the sedimentation compartment (20). Above the sedimentation compartment (20) there is located a flooded first fixed bed reactor (22) for microbiological denitrification, which is flowed through from below. The water travels by way of an overflow device (34) and a sprinkler system (36) through which dissolved nitrogen is stripped and oxygen enrichment from the air occurs, into a second fixed bed reactor (38) for microbiological denitrification. This is constructed as a drip device, and is flowed through by air in a chimney-like fashion. Below the second fixed bed reactor (38) is located a catch basin (44) with a drain (54).
